During January 2015 to December 2020 there were 17 cases of orbital lymphoma who went to M. Djamil Hospital Padang, majority of male patients, with a mean range of age 60 years.
The most clinical manifestations of orbital lymphoma were proptosis (58.82%) followed by a palpebral mass (41.18%) and most cases were unilateral.
All patients were performed orbital CT scan and histopathological examination. Most of patients were non-Hodgin lymphoma with small lymphocytic type which is a low grade lymphoma.
There was one patient with a mismatch between clinical manifestations and histopathological results so the histopathological examination was reviewed again.
The management performed in this orbital lymphoma patient was chemotherapy in 16 patients and 1 patient refused chemotherapy and performed an anterior orbitotomy.
OCULAR MANIFESTATIONS of HYPOPHYSEAL ADENOMAMeironi Waimir
Hypophyseal adenoma is a benign tumor with slow growth, comes from cells of the hypophyseal gland and is an intracranial tumor that can affect optic chiasm.
Neuro-ophthalmological manifestations depend on the location, size and invasion to the surrounding tissue. Neuro-ophthalmologic manifestations can occur vision loss, visual field defects: bitemporal hemianopsia, junctional scotoma, central bitemporal hemianopsia, bilateral superior temporal quadranopsia and homoym hemianopsia. Additionally papiledema, ophthalmoplegi and pituitary apoplexy can occur.

FDG PET/CT plays an important role in staging, restaging, prognostication, planning treatment strategies, monitoring therapy, and detecting relapse. In this lecture I try my best to explain it for our fellows .
• The tumor microenvironment consists of four components:
o Cancer cells
o Non-cancer cells
o Secreted soluble factors
o Non-cellular, solid material
• The actual composition of the tumor microenvironment is highly variable.
• The immune system can inhibit or promote tumor growth.
• Many cancers are associated with chronic inflammatory conditions that activate cells of the innate immune system.
• Macrophages secrete factors that enhance tumor cell proliferation, invasion• Fibroblasts are the predominant cells in the stroma.
• Changes in fibroblast behavior are associated with tumor progression.
• Matrix metalloproteinases (MMPs) produced by fibroblasts degrade the extracellular matrix.
• MMPs are key players in cancer initiation, metastasis, and angiogenesis.
, and promote angiogenesis.
One of the most critical roles performed by fibroblasts, both in normal and cancer tissue, is the production and remodeling of the extracellular matrix (ECM). Not only does the ECM impart structural support and strength to tissues, it also provides attachment sites for cell surface receptors, and functions as a reservoir of cytokines and other growth factors27The structure of tumor-associated ECM is abnormal, with loose structure and disorganized collagen fibers28Matrix metalloproteinases (MMPs) are a large family of enzymes capable of degrading components of the ECM and are critical in maintenance of the ECM. Degradation of the ECM by MMPs releases growth factors, enhances migration, and alters cell:cell and cell:ECM interactions29. Although MMPs can be produced by tumor cells, most are produced by fibroblasts and macrophages, and high levels of MMPs are found at the tumor:stroma interface7. Because MMPs are secreted into the surrounding environment by these cells, they are a good example of the interaction that occurs between a tumor and its environment.

Minimally Invasive Glaucoma Surgery (MIGS)Meironi Waimir
Minimally invasive glaucoma surgery (MIGS) is a group of procedures that minimizes the invasive rate of glaucoma with five characteristics: ab interno microincision, minimal trauma, more effective, high safety profile, and quick recovery.
MIGS is a surgery that uses an incision in a clear cornea and is indicated in patients with mild to moderate open angle glaucoma.
The technique of MIGS is based on several mechanisms, namely trabecular meshwork bypass stents including iStent, trabectome, and Hydrus microstent; Suprachoroidal implant using Cypass microstent; And subconjungtiva filtration using XEN gel stent.
MIGS technology has potential advantages in glaucoma management by reducing the burden of treatment, improving patients quality of life, and cutting or delaying more invasive surgeries.
Otot ekstraokuler memegang peranan penting dalam sistem visual, yaitu dengan memfasilitasi kesejajaran binokular yang penting untuk stereopsis dan mempertahankan target visual agar bayangan tepat jatuh di fovea. Strabismus merupakan suatu kelainan dimana tidak ditemukannya kesejajaran visual aksis pada kedua mata yang dapat disebabkan oleh kelainan pada otot ekstraokuler itu sendiri dimana salah satu atau lebih dari otot-otot tersebut tidak dapat berfungsi dengan baik. Inferior oblique overaction (IOOA) sering ditemukan dibanding semua overaksi otot ekstraokuler dan sering menyertai strabismus horizontal.1,2
IOOA ditandai dengan adanya overelevasi pada saat adduksi. Saat memeriksa versi pada seorang pasien, dapat ditemukan suatu up shoot yang nyata saat mata bergerak adduksi, kelainan ini dapat terjadi unilateral atau bilateral, dan dinamakan inferior oblique overaction atau strabismus sursoadductorius. IOOA disebut sebagai primer bila tidak terkait dengan paralisis otot oblik superior. Disebut sekunder bila disertai parese atau palsy dari antagonisnya, otot oblik superior.3,4,5
IOOA terkait dengan deviasi horizontal. IOOA dilaporkan terjadi pada sekitar 70% pasien dengan esotropia dan 30% pasien dengan eksotropia. Penyebab IOOA primer ini masih belum jelas.6
IOOA juga dapat terkait dengan eksotropia baik itu intermiten atau konstan, atau dapat terjadi sebagai overaksi dari muskulus oblik inferior saja tanpa jenis strabismus lainnya. IOOA tanpa strabismus lainnya mungkin akibat suatu congenital superior oblique palsy. Bila tes headtilt negatif mengindikasikan suatu IOOA primer. Karena parese oblik superior akan menghasilkan IOOA, pembedaan antara overaksi dari muskulus oblik inferior akibat parese oblik superior dapat menjadi sulit.7,8
Pada kasus dengan IOOA, perlu dilakukan suatu prosedur untuk melemahkan otot tersebut. Prosedur ini dapat dilakukan dengan teknik reses, disinsersi, miektomi, miotomi, transposisi anterior atau teknik denervasi dan ekstirpasi.5
Pada makalah ini, akan dibahas mengenai anatomi dan fisiologi muskulus oblik inferior, manifestasi klinis, differensial diagnosis, dan penatalaksanaan inferior oblique overaction.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Lymphoma lymphoid malignancy originating from the clonal proliferation of B lymphocytes, T
lymphocytes, or natural killer (NK) cells.
Lymphoma Hodgkin lymphoma, which originates from B lymphocytes, and Non Hodgkin's
lymphoma originating from different clones.
The cause of cell mutation in lymphoma is not certain
Monoclonal theory neoplastic changes initially affect one cell which then multiplies and gives rise
to neoplasms.
Environmental theory related to carcinogenic agents changes at various stages in the growth
of normal blood cells neoplastic clones cause swelling of the lymph nodes.
7. • Late onset and slow progression over
many years to show clinical symptoms.
• Usually unilateral but can also bilateral.
• 50-70 year age group.
• Affects both genders with a slightly more
predilection for women
CLINICAL MANIFESTATIONS
• The clinical manifestations non-
specific, depending on the location of
the lymphoma.
• Visual acuity usually undisturbed,
because infiltration to optic nerve is
rare
9. CLASSIFICATION OF LYMPHOMA
In general lymphoma is classified into Hodgkin's lymphoma and Non-Hodgkin's lymphoma.
Classification according to Rappaport
• First introduced in 1956 and then modified in
1978.
• Classified based on cytology and histology.
Working Formulation
• Compiled by the National Cancer Institute in
1982.
Classification Characteristics
Low
- Small lymphocytic
- Follicular,predominantlysmallcleaved cell
- Follicular,mixed,smallcleavedcellandlarge cell
Intermediate
- Follicular,predominantlylarge cell
- Diffuse,mixed,smalldanlarge cell
- Diffuse,largecell(cleavedand noncleaved)
High
- Diffuse large cell, immunoblastic
- Lymphoblastic (convoluted and non-
convoluted)
- Small noncleaved cell
10. CLASSIFICATION OF LYMPHOMA

• Based on clinical morphology, immunophenotype, genotype, and clinical manifestations of lymphoma.
MALT lymphoma
(Mucosa-Associated Lymphoid Tissue)
Chronic Lymphocytic Lymphoma (CLL)
Follicular Center Lymphoma
High Grade Lymphomas
• Low grade lesion, 40-60% of orbital lymphoma.
• Spontaneous remission in 5-20% of cases, but can also undergo a
histological transformation become more aggressive.
• Low grade lesion of lymphocytes that appear mature
• Low grade lesion with a follicular center.
• Including large cell lymphoma, lymphoblastic lymphoma and
Burkitt lymphoma.
11. GRADING AND STAGING OF LYMPHOMA
Grading Describes the progression of the disease
Staging The extent of organ involvement in lymphoma
The Ann Arbor Staging System is the most commonly used staging system for orbital lymphoma.
Low Grade
• Indolent or slow growth rate.
Intermediate Grade
• Moderate growth rate.
High Grade
• Aggressive or rapid growth rate.
Stage I
• Confined to
the orbit.
Stage II
• Involvement
of adjacent
structures
such as the
sinuses,
tonsil, and/or
nose.
Stage III
• Abdominal
nodal disease
below the
diaphragm.
Stage IV
• Disseminated
involvement
of one or
more
extranodal
sites, such as
liver or bone.
12. DIAGNOSIS
The diagnosis of orbital lymphoma History and physical examination, complete blood count,
imaging (CT scan or orbital MRI), and biopsy.
Systemic examination to determine the involvement of other organs very important in orbital
lymphoma Collaboration with an internist.
CT scan
homogeneous and isodense texture to muscle, showing mild contrast-enhanced improvement.
Lymphoma usually does not cause bone destruction.
13. DIAGNOSIS
MRI
Isointense or hypointense mass on T1-weighted, but appears isointense to hyperintense on T2-
weighted.
MRI of a large cell lymphoma patient with multiple intraorbital
masses infiltrating the lacrimal gland and extraocular muscles.
14. DIAGNOSIS
Histopathological examination
Important diagnostic step in the management of orbital lymphoma.
Open biopsy or fine-needle aspiration biopsy (FNAB)
Diagnosis of lymphoma is confirmed when diffuse immature cells are found and lymphocytes
that are actively mitotic.
16. DIFFERENTIAL DIAGNOSIS
The differential diagnosis of orbital lymphoma is extensive, due to the lack of specific
features for orbital lymphoma.
The differential diagnosis for orbital lymphoma includes:
• Benign lymphoproliferative lesions,
• Orbital tumor metastases,
• Pseudotumor,
• Lacrimal adenoma,
• Cavernous hemangioma, and
• Diffuse lymphangioma.
17. Observation Surgical

MANAGEMENT
Some of the main criteria for the choice of optimal therapy and treatment are:
lymphoma histopathological subtypes, the extent of the disease inside and outside the periocular area, prognostic
factors associated with the patient and disease, and the impact of orbital lymphoma on visual function.
18. MANAGEMENT
Observation
Controversial
May be used in frail elderly patients with asymptomatic disease or in severe comorbid that
preclude aggressive therapeutic approaches.
Surgical Therapy
• Diagnostic and therapeutic.
Diagnostic Biopsy
Surgical resection Capsulated tumors, such as tumors of the lacrimal gland and
conjunctiva.
• Microinfiltration of the tumor into the surrounding tissue the risk of recurrence.
• Surgery as a primary therapy is not recommended.
19. MANAGEMENT
Radiotherapy
Therapeutic option in patients with early stage and localized orbital lymphoma.
The dose depends on the stage of orbital lymphoma.
Radiotherapy doses of 25-35 Gy are recommended in low grade lymphoma.
Chemotherapy
For more aggressive histological subtype orbital lymphoma with potential for systemic
involvement and distant metastases such as large diffuse B-cell lymphoma.
Usually done after surgical therapy, radiotherapy or in patients with an advanced stage.
Indolent lymphoma is very sensitive to single agent and combination chemotherapy.
20. MANAGEMENT
Monotherapy

Combination regimen cyclophosphamide,
doxorubicin, vincristine, and prednisone
(CHOP) or cyclophosphamide, vincristine,
doxorubicin, and dexamethasone (CVAD).
Chemotherapy
Immunotherapy
Anti-lymphocyte antibodies New form of lymphoma treatment.

27. DISCUSSION
17 patients with orbital lymphoma who were treated at M. Djamil Hospital Padang in the period
January 2015 to December 2020 13 male (76.47%) and 4 female (23.53%).
Sjo LD (2009)
• Majority of
orbital
lymphomas were
found in male.
Olsen et al
(2019)
• More cases in
men: 52% of men
and 48% of cases
in women.
Ahmed et al
(2020)
• More cases in
women 53.3%
and 46.7% male.
There are variations in gender in cases of orbital lymphoma
28. DISCUSSION
Sharma et al
(2015)
• Orbital
lymphoma can
appear in the
age range of 15 -
70 y.o mostly
in old age.
Olsen et al
(2019)
• The average age
of patients with
orbital
lymphoma who
came to
treatment was
73% over 50 y.o.
Ahmed et al
(2020)
• The average age
of orbital
lymphoma
patients in the
United States is
66 years.
In this study The average age of patients was 60 years. The youngest age was 44 years
and the oldest age was 84 years
29. DISCUSSION
The most manifestation of orbital lymphoma was proptosis (58.82%) and mass in the
palpebra (41.18%). Almost all manifestations were unilateral (82.35%).
The majority of orbital lymphoma presents unilateral manifestations,
especially in B cell lymphoma, up to 90%.
Salmon patch appearance
On the medical records were not found, because almost all
patients came with chief complaints of protusion accompanied
by chemosis The appearance of the salmon patch is difficult to
judge. Mr. N, 65 y.o was diagnosed with orbital
lymphoma with clinical manifestations of a mass
in the superior palpebrae on the RE.
30. DISCUSSION
All patients with suspected orbital lymphoma CT scan and biopsy.
CT scan All performed as an orbital mass and showed the impression of a lymphoma.
The histopathological examination Non-Hodgkin's lymphoma with small lymphocytic type in
88.24% and large cell type in 11.76%.
An estimated 85-90% of orbital lymphomas are low grade, with small, monoclonal and diffuse
proliferation of B-cell lymphocytes. Whereas follicular or nodular features are found only 10-15%
of cases
31. DISCUSSION
One patient has two
histopathological examination results.
The first biopsy reactive
hyperplasia of the lymph nodes.
The second histopathological result
a small cell type non-Hodgkin's
lymphoma.
All patients consulted to the
Internal Medicine Department to find
out any accompanying systemic
abnormalities.
All patients had systemic
abnormalities.
32. Surgical therapy alone is not recommended
high risk of relapse after surgery.
Radiotherapy as initial therapy has been
reported to be very effective in orbital
lymphoma, especially in MALT.
DISCUSSION
The management Chemotherapy in 16 patients (94.12%) and 1 patient (5.88%)
anterior orbitotomy surgery and refusing chemotherapy.
Chemotherapy is performed by internists using the CHOP regimen
33. DISCUSSION
Systemic chemotherapy effective therapies for orbital lymphoma.
Mainly given in the form of a combination post surgery and radiotherapy
or given alone in stage III and IV lymphoma.
In more aggressive lymphoma, chemotherapy is the more appropriate
option.
In this study Chemotherapy was recommended. The regimen used was
cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP).
34. CONCLUSION
During January 2015 to December 2020 there were 17 cases of orbital
lymphoma who went to M. Djamil Hospital Padang, majority of male
patients, with a mean range of age 60 years.
The most clinical manifestations of orbital lymphoma were proptosis
(58.82%) followed by a palpebral mass (41.18%) and most cases were
unilateral.
35. CONCLUSION
All patients were performed orbital CT scan and histopathological
examination. Most of patients were non-Hodgin lymphoma with small
lymphocytic type which is a low grade lymphoma.
There was one patient with a mismatch between clinical manifestations
and histopathological results so the histopathological examination was
reviewed again.
The management performed in this orbital lymphoma patient was
chemotherapy in 16 patients and 1 patient refused chemotherapy and
performed an anterior orbitotomy.

Lymphoma is divided into Hodgkin lymphoma,.....originating from different clones (B cell lymphoma, T cell lymphoma, and NK cell lymphoma).
Orbital lymphoma has a late onset and slow progression over many years to show clinical symptoms.
Most orbital lymphomas are of the Non-Hodgkin type which occurs mainly in the 50-70 year age group
Proptosis
Slow mass growth, painless, unconscious onset, causing inferior displacement of the eyeball, palpebral edema, and dense elastic palpable mass.
Ptosis
Lymphoid lesions originate on the eyelids found in the dermis or orbicularis muscles of the upper eyelids.
Salmon-patch appearance
Lymphoid lesions of the conjunctiva appear as conjunctival edema which is pink, movable from the base, on the substantia propria of the conjunctiva
Classified lymphoma into low, intermediate, and high grade based on histological characteristics and morphological features.
Brain CT scan shows a lesion in the left orbital that looks aggressive, with contrast enhancement showing retro-orbital extension involving the optic nerve and frontoethmoid sinus.
The specimen is collected by open biopsy or a fine-needle aspiration biopsy (FNAB)
