Sexually transmitted diseases (pictures)
This document provides an overview of common sexually transmitted diseases including primary and secondary syphilis, gonorrhea, chlamydial infection, lymphogranuloma venereum, genital herpes, chancroid, pediculosis, and condyloma acuminata. It includes pictures and links to additional nursing resources on sexually transmitted diseases.
Malignant Melanoma
Malignant melanoma is a rapidly spreading skin cancer that can occur at any age. It arises from melanocytes and spreads locally and systemically through lymphatics and blood vessels. Risk factors include excessive sun exposure, the presence of moles or dysplastic nevi, and family history. There are several clinical variants classified by their appearance and prognosis, with nodular melanoma having the worst prognosis. Diagnosis involves histological examination showing malignant melanocytes in the skin with features of invasion and metastasis. Treatment involves surgical excision and may include lymph node dissection, chemotherapy, or immunotherapy. Prognosis depends on the depth of tumor invasion.
Meningiomas
Benign tumors called meningiomas originate from cells of the arachnoid layer of the meninges and are attached to the dura mater. They commonly present as well-defined masses compressing the brain but can be easily separated. Multiple meningiomas, acoustic schwannomas, and gliomas may indicate neurofibromatosis type 2, while around 50% of solitary meningiomas have a mutation in the 22q gene. Meningiomas demonstrate distinct histological patterns including syncytial, fibroblastic, transitional, psammomatous, and secretory variants.
Melanoma and melanoma types with treatment
1. Melanoma is a malignant tumor of melanocytes that can arise in the skin or other parts of the body.
2. Risk factors for melanoma include excessive exposure to UV radiation, fair skin, and family history.
3. There are several types of melanoma including superficial spreading, nodular, lentigo maligna, and acral lentiginous melanoma.
4. Prevention strategies include avoiding sun exposure, wearing protective clothing, and eating a diet high in antioxidants. Medical treatment options include immunotherapy, chemotherapy, radiation therapy, targeted therapy and biologic therapy.
Malignant melanoma
This document discusses melanoma and its characteristics. It notes that pigmentation is a hallmark of melanoma. Features suggestive of melanoma include changes in existing pigmented lesions or presence of irregular, asymmetrical, or multiple colored lesions over 6mm in diameter. Risk factors include white race, older age, and intense sunlight exposure. Pathology shows anaplastic malignant melanocytic cells. Types include lesions arising from nevi or de novo. Diagnosis and treatment options are also summarized.
Dural tumors made easy (radiology)
This document summarizes different types of dural tumors. It discusses meningiomas, which originate from meningeal cells and are the most common non-glial brain tumor. It also covers hemangiopericytomas, which are highly vascular tumors of uncertain origin, and melanocytomas, which are benign tumors arising from leptomeningeal melanocytes. For each tumor type, the document discusses histology, genetics, symptoms, imaging appearance on techniques such as CT, MRI, and angiography, and other characteristics.
Histopathology of malignant melanoma
This document discusses the histopathology of malignant melanoma. It describes several types of melanoma including superficial spreading melanoma, nodular melanoma, lentigo maligna melanoma, and acral lentiginous melanoma. Key points include that melanoma most commonly affects sites like the scalp, orbit and face in individuals between 20-60 years old. Histopathological examination reveals expansile nodules of atypical melanocytes with mitotic figures. Important prognostic factors mentioned are tumor thickness, ulceration, mitotic rate, lymphocytic infiltration, vascular invasion and presence of satellite lesions. Differential diagnoses and features useful to distinguish melanoma from benign lesions are also provided.
Topic of the month: Radiological pathology of meningiomas
This document discusses radiological imaging of meningiomas. It begins by providing background on meningiomas, including that they are the most common primary brain tumor and usually occur in women aged 40-60. On CT scans, meningiomas typically appear dense with calcification and enhance strongly with contrast. On MRI, characteristics vary depending on the histological subtype, with syncytial and angioblastic subtypes more likely to exhibit cysts or increased signal intensity. Location of meningiomas also provides clues to symptoms. The document discusses imaging features of different histological subtypes and common meningioma locations in the brain and spine.

Meningioma
Meningioma is a type of tumor that arises from the meninges, the protective layers surrounding the brain and spinal cord. It is the most common primary brain tumor, accounting for about 20% of all primary central nervous system tumors. Meningiomas most often occur in adults and are more common in women. While the majority of meningiomas are benign, radiation exposure, genetic conditions, and hormone therapy can increase the risk of a malignant type. Imaging plays an important role in the diagnosis and treatment planning of meningiomas.
Neuro d dx
This document provides a differential diagnosis for various neurological and head/neck conditions organized by location and imaging findings. Some of the most common causes included are:
1. Intracranial hemorrhage is most often due to hypertension, tumors, trauma, or aneurysms.
2. Aneurysms are commonly saccular and degenerative or traumatic in nature.
3. Spinal cord compression is often caused by compression fractures, disk disease, or primary bone disorders like Paget's disease.
4. Intracanalicular internal auditory canal masses are typically acoustic neuromas or facial neuromas.
Malignant melanoma A-Z
Malignant melanoma arises from melanocytes and most commonly occurs on the skin. It ranges from early radial growth phase to advanced vertical growth phase and metastasis. Risk factors include sun exposure, fair skin, and family history. Diagnosis involves biopsy of suspicious lesions. Staging uses Breslow and Clark levels as well as TNM classification. Treatment depends on stage but commonly includes surgical resection with sentinel lymph node biopsy and adjuvant immunotherapy or chemotherapy for advanced cases. Prognosis depends on stage, with thin early lesions having good prognosis.
Malignant Melanoma
This document provides an overview of malignant melanoma, including its aetiology, types, risk factors, diagnosis, staging, treatment, and prevention. Malignant melanoma arises from melanocytes in the basal layer of the skin and less commonly in the eye or meninges. The main types are superficial spreading melanoma, nodular melanoma, acral lentiginous melanoma, and lentigo maligna melanoma. Risk factors include excessive sun exposure, genetic predisposition, numerous benign moles, and family history. Diagnosis involves examining moles for changes in size, irregular pigmentation, asymmetry, and diameter. Prognosis depends on the Breslow thickness and presence of ulceration. Treatment involves surgical resection with chemotherapy or immunotherapy in
Melanoma
Designed for medical/allied health professionals with an emphasis on radiological and nuclear medicine aspect of Malignant Melanoma.
Melanoma
Melanoma is the most serious type of skin cancer. Often the first sign of melanoma is a change in the size, shape, color or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal or "ugly looking."
Thinking of "ABCD" can help you remember what to watch for:
Asymmetry - the shape of one half does not match the other
Border - the edges are ragged, blurred or irregular
Color - the color is uneven and may include shades of black, brown and tan
Diameter - there is a change in size, usually an increase
Melanoma can be cured if it is diagnosed and treated early. If melanoma is not removed in its early stages, cancer cells may grow downward from the skin surface and invade healthy tissue. If it spreads to other parts of the body it can be difficult to control.
Meninges and related tumors
The document discusses meninges and related tumors. It begins by describing the three layers of meninges - the outer dura mater, middle arachnoid mater, and inner pia mater - that cover and protect the brain. It then discusses different types of primary meningeal tumors, focusing on meningiomas. Meningiomas are the most common type of meningeal tumor in adults. The document outlines various subtypes of meningiomas, genetic factors involved in their development and malignant progression, typical locations, clinical features, microscopic appearance and distinguishing characteristics of different histological subtypes.
Melanoma
This document provides information on malignant melanoma. Some key points:
- Melanoma is a malignancy of melanocytes that can occur in skin, eyes, and mucous membranes. It has a high ability to metastasize to other organs.
- Incidence is increasing worldwide. Risk factors include fair skin, moles, UV exposure, and family history.
- Diagnosis involves examining lesions for characteristics like asymmetry, irregular borders, varied color, and size over 6mm. Biopsies are used to confirm.
- Staging uses the TNM system and considers tumor thickness, ulceration, and lymph node/distant organ involvement. Prognosis depends on stage - thicker tumors over 2mm
Meningeal Based Intracranial Masses Beyond Meningioma
Dural based masses other than meningioma ( which is the most common dural based intracranial mass) their appearance on imaging modalities such as CT and MRI.
Cancer of the skin (malignant melanoma)
Malignant melanoma is the most lethal form of skin cancer that can develop in several forms from melanocytes in the epidermis and dermis. Risk factors include fair skin, red/blond hair, family history, and sun exposure. Symptoms vary depending on the type but may appear as irregular colored lesions. Diagnosis involves biopsy and staging tests. Treatment options depend on invasion depth and may include surgery, chemotherapy, and immunotherapy. Nursing focuses on managing pain, reducing anxiety, educating on symptoms of metastasis, and supporting the patient.
Mailgnant melanoma
This document provides an overview of melanoma, including its causes, risk factors, types, diagnosis, staging, and treatment. It discusses that melanoma arises from melanocytes, can spread from the skin to other organs, and accounts for the majority of skin cancer deaths. Early detection through changes in moles is important for improved prognosis, as thickness and spread determine survival rates. Surgical removal is the main treatment, and sentinel lymph node biopsy helps determine if it has spread to lymph nodes.
Melanoma
- Melanoma is a malignant tumor arising from melanocytes that produces melanin. It is more common in whites due to higher UV exposure and occurs most often on head/neck, trunk and limbs. Risk factors include fair skin, moles, family history and sun exposure.
- There are several clinical types including superficial spreading, nodular, lentigo maligna, acral and amelanotic melanomas. Staging uses Breslow thickness, Clark levels, and TNM classification. Diagnosis involves biopsy and imaging tests.
- Treatment depends on stage and includes surgery, lymph node dissection, chemotherapy, immunotherapy and radiation. Prognosis is best for early stage disease and worse for advanced stages
Melanoma presentation
Melanoma is the sixth most common cancer in the US, with 68,000 new cases diagnosed each year and 8,700 annual deaths. Risk factors include fair skin, light eyes, family history, and sun exposure. Melanoma has been recognized as a disease since 1806 and stages range from Stage 0 precancerous lesions to Stage IV metastatic cancer. Treatment options depend on the stage and may include surgery, radiation, immunotherapy, and experimental therapies.
Melanoma
This document summarizes melanoma, a type of skin cancer. It originates from melanocytes in the skin or mucosal surfaces. Melanoma is more common and dangerous in white people and younger women. The main risk factor is ultraviolet radiation from the sun or tanning beds. There are four main types of melanoma named after their appearance or location on the skin. Doctors diagnose melanoma through history, physical exam, and biopsy. It is staged based on how deep it has penetrated the skin and if it has spread. Treatment options range from surgery for early stages to immunotherapy and chemotherapy for later stages.
extra axial Meningioma
This document discusses extra-axial masses, specifically meningiomas. It provides details on the typical presentation, demographics, pathology, imaging features and diagnosis of meningiomas. On imaging, meningiomas usually appear as well-circumscribed, dural-based masses that enhance strongly with CT and MRI. They typically show calcification on CT and homogenous enhancement post-contrast. The document emphasizes that meningiomas are the most common extra-axial brain tumors and often appear as convexity or parasagittal masses, with females being more commonly affected.
Malignant Melanoma
Malignant melanoma diagnosis and management has advanced recently. Melanoma arises from melanocytes and can affect the skin, eyes, or internal organs. Recent trends include more accurate staging using tumor thickness, ulceration, and mitosis rate rather than Clark's level. Sentinel lymph node biopsy helps stage intermediate thickness melanomas. For advanced cases, targeted therapies like BRAF inhibitors and immunotherapies have improved outcomes. Wide local excision remains the main surgical treatment, with reconstruction to optimize function and allow adjuvant therapies. Long-term follow-up is important due to the risk of late recurrence.

Malignant melanoma of the Eyelid
Malignant melanoma of the eyelid is a rare and aggressive form of skin cancer that arises from malignant melanocytes in the eyelid. Risk factors include fair skin, dysplastic nevi, family history, and sun exposure. Diagnosis involves clinical examination looking for asymmetry, irregular borders, color variation and diameter using the ABCD method along with biopsy for histological examination. Treatment of early stage melanoma involves surgical excision with wide margins or Mohs micrographic surgery. Sentinel lymph node biopsy is recommended for melanomas thicker than 0.75mm.
Melanoma
This document summarizes key information about melanoma. It discusses the increasing incidence rates of melanoma and describes the different types, including superficial spreading, nodular, lentigo maligna, and acral lentiginous. Prognostic factors like Breslow thickness, ulceration, location, and gender are covered. Treatment options are outlined, including surgical excision for early-stage melanoma and immunotherapy or chemotherapy for advanced or metastatic disease. Future treatments under investigation include vaccines, monoclonal antibodies, and radiation therapy.
CNS SPECT
This document discusses 6 applications of CNS SPECT imaging: 1) Evaluating collateral circulation during internal carotid balloon test occlusion, 2) Evaluating amobarbital sodium distribution during the Wada test, 3) Evaluating vasospasm associated with subarachnoid hemorrhage or cerebral angiography, 4) Evaluating cerebrovascular reserve before carotid endarterectomy, 5) Presurgically localizing seizure foci, and 6) Guiding stereotactic biopsy for evaluation of tumor recurrence.
MENINGIOMA - SIGNS
Meningiomas can be identified through several characteristic signs seen on imaging scans. These signs include the CSF cleft sign, dural tail, ginkgo leaf sign, mother in law sign, spoke wheel sign, sunburst sign, and white matter buckling sign which help doctors diagnose meningiomas.
second impact syndrome
This document discusses second impact syndrome and concussion grading. It defines concussion as an immediate loss of consciousness due to a blow to the head. A second, less intense impact before recovery from an initial concussion can lead to malignant cerebral edema and sudden death within minutes due to loss of the brain's autoregulatory mechanism. It presents the CANTU grading system for concussions from Grade 1 to 3 based on loss of consciousness time and post-traumatic amnesia duration. It outlines return to play protocols depending on concussion grade and whether it is a first or second concussion to prevent second impact syndrome.
