Malignant tumors involving paranasal sinuses
This document provides an overview of nose and paranasal sinus malignancies. It discusses their epidemiology, common types including squamous cell carcinoma and adenocarcinoma, risk factors such as wood dust exposure, clinical presentation, imaging, staging systems, and treatment options including surgery and radiotherapy. Nose and paranasal sinus cancers are uncommon but can cause significant morbidity due to their location near critical structures like the orbit and brain. Accurate diagnosis is challenging as symptoms often mimic rhinosinusitis initially. Treatment aims to balance tumor control with preserving quality of life and important functions.
Paranasal sinuses carcinoma
1. Carcinomas of the paranasal sinuses most commonly arise in the maxillary sinus (70% of cases). Squamous cell carcinoma is the most common histologic subtype (80-85% of cases).
2. Presentation varies by location but commonly includes nasal symptoms like obstruction or discharge, oral/dental symptoms, and ocular findings like proptosis or diplopia. Diagnosis is aided by CT or MRI imaging which can detect bone erosion and intracranial extension.
3. Treatment involves surgery such as maxillectomy or ethmoidectomy along with postoperative radiotherapy. Prognosis depends on tumor stage and extent, with 5-year local control rates ranging from
Management of ca maxillary sinus
Maxillary sinus carcinoma arises from the maxillary sinus and can spread locally and to lymph nodes. Diagnosis involves physical exam, CT/MRI imaging, and biopsy. Staging evaluates tumor size, lymph node involvement, and distant spread. Treatment depends on stage but may include surgery such as maxillectomy, radiation therapy such as IMRT, and chemotherapy such as cisplatin for locally advanced cases. The goal of treatment is a complete resection with negative margins or effective control with radiation with or without chemotherapy while minimizing side effects to nearby structures like the optic nerves and chiasm. Outcomes depend on stage, with earlier stages having higher survival rates treated with surgery or surgery plus radiation.

This document discusses various fibro-osseous tumors of the sinonasal region, including fibrous dysplasia. Fibrous dysplasia is a benign condition caused by a defect in osteoblast differentiation and maturation, resulting in the replacement of normal bone by fibrous connective tissue. It is caused by mutations in the GNAS1 gene. Histologically, there is slow replacement of medullary bone by abnormal fibrous tissue at different stages of bone metaplasia. Fibrous dysplasia typically presents in children and adolescents, with females being affected more often than males.

It covers the anatomy of head and neck regions, risk factors, diagnostic procedures like physical examination and imaging, and treatment modalities including surgery, radiation therapy, chemotherapy, and targeted therapy. Multidisciplinary treatment approaches are emphasized to improve outcomes for locoregionally advanced head and neck cancer.Pathology of pharynx
1) Rathke's pouch forms the pituitary gland, which must migrate to the hypothalamus during development. In some individuals, pituitary tissue remains in the roof of the pharynx.
2) Down syndrome results from trisomy 21 and is characterized by midface hypoplasia, reducing nasopharynx and oropharynx volume.
3) Crouzon syndrome is an autosomal dominant craniosynostosis with midface hypoplasia and relative mandibular prognathism, potentially causing airway obstruction.
Cancer of the nasopharynx
Nasopharyngeal carcinoma is a rare cancer that arises from the epithelial lining of the nasopharynx. It is most common in Southern China and Southeast Asia. Risk factors include Epstein-Barr virus infection and dietary factors. Symptoms include neck masses, nosebleeds, nasal obstruction, and cranial nerve palsies. Diagnosis involves endoscopic biopsy and imaging tests like CT and MRI. Treatment primarily consists of radiation therapy, which can cause both acute and chronic side effects. Prognosis depends on cancer stage, with advanced cases having poorer outcomes and higher risk of distant metastasis.

1. Carcinoma of the oral cavity is most commonly found on the tongue, floor of mouth, and lips. It spreads locally and via lymphatics, most often to cervical lymph nodes. Distant metastases occur in 15-20% of cases, most commonly to lungs.
2. Diagnosis involves history, physical exam, biopsy of the lesion and lymph nodes, imaging like OPG, CT/MRI to assess bone and lymph node involvement. Staging helps determine prognosis and management.
3. Treatment involves surgery, radiation, chemotherapy depending on stage. Close surveillance is needed due to high risk of recurrence and second primary cancers.
Oral cancer
This document summarizes key information about oral cancer:
1) Oral cancer is a major malignancy in the Indian subcontinent, affecting males over 60 years old at a higher rate. Risk factors include smoking, alcohol, betel nut and spice chewing.
2) Premalignant lesions like leukoplakia and erythroplakia are associated with increased risk of oral cancer. Conditions like submucous fibrosis from betel chewing can also progress to oral squamous cell carcinoma.
3) Patient workup for oral cancer involves history, clinical exam, biopsy or FNAC of suspicious lesions, and imaging tests. Staging follows AJCC guidelines and helps determine prognosis and guide treatment.
Tumours of pharynx
The document discusses tumours of the pharynx, including benign and malignant tumours of the nasopharynx and oropharynx. In the nasopharynx, juvenile nasopharyngeal angiofibroma is the most common benign tumour seen in adolescent males. Nasopharyngeal carcinoma is the most common malignancy and is strongly associated with Epstein-Barr virus. In the oropharynx, common benign tumours include mucous retention cysts and papillomas, while squamous cell carcinoma is the most frequent malignancy, associated with risk factors like smoking, alcohol, and HPV 16.

The document discusses the lymphatic system of the neck. It notes that there are approximately 75 lymph nodes on each side of the neck. The neck lymph nodes drain various areas of the head and neck and are commonly involved in metastases of head and neck tumors. The key lymph node groups of the neck are described along with the specific areas they drain. Staging of head and neck cancer is also mentioned briefly.
Pleomorphic adenoma surgical management
Mr. X, a 55-year-old male, presented with a gradually enlarging painless swelling in his left parotid region over the past 5 years. Examination revealed a 7 cm x 6 cm firm, non-tender mass that was mobile and had a well-defined margin. Investigations including FNAC, USG, and MRI confirmed a diagnosis of pleomorphic adenoma. The patient underwent a superficial parotidectomy to remove the tumor. Histopathology of the resected specimen confirmed pleomorphic adenoma. The postoperative course was uneventful with intact facial nerve function and no complications.
ENT tumors (Revisi) neoplastic and non neoplastic.ppt
Nasal polyps are benign lesions that arise from the nasal cavity or paranasal sinus mucosa. They are more common in adults over age 40 and in males. Chronic inflammation, allergy, and genetic factors may contribute to their development. Nasal polyps cause symptoms like nasal obstruction, postnasal drip, and headaches. Diagnosis involves nasal examination and imaging tests, while treatment consists of medical management with corticosteroids or surgical removal.
Adenoid cystic carcinoma (Doctor Faris Alabeedi MSc, MMedSc, PgDip, BDS.)
Adenoid cystic carcinoma is a slow growing malignancy of the salivary glands composed of epithelial and myoepithelial cells forming tubular, cribriform, and solid patterns. It most commonly occurs in major salivary glands and has a female predominance. Patients typically present with swelling or masses and may experience numbness or pain. Histologically, it is graded based on patterns and prognosis is influenced by factors like perineural invasion, stage, and solid growth patterns conferring a worse prognosis. A defining genetic characteristic is a translocation involving the MYB oncogene.
Nasopharyngeal carcinoma
This document provides an overview of nasopharyngeal carcinoma (NPC), including its epidemiology, etiology, histological classification, clinical features, diagnosis, staging, treatment and prognosis. NPC has a unique geographical and ethnic distribution. It is caused by an interaction between genetic factors, Epstein-Barr virus infection and environmental exposures. Diagnosis involves biopsy of suspicious nasopharyngeal lesions. The main treatment is radiotherapy, while chemotherapy may be added for advanced cases. Prognosis depends on stage, with 5-year survival rates ranging from 80-90% for early stage to 20-40% for stage IV disease.
Oral cancer pwr.pnt.
This document provides an overview of malignancies of the lips and oral cavity. It discusses the cellular biology of the oral epithelium and various molecular markers. Risk factors for oral cancer include tobacco, alcohol, HPV infection, and genetic syndromes. Common sites are the tongue, floor of mouth, and lower alveolus. Symptoms include sores that don't heal, lumps, pain, and difficulty swallowing. Molecular changes involve tumor suppressor genes and oncogenes.
pharyngeal Tumors
Nasopharyngeal carcinoma (NPC) is a cancer with a poor prognosis due to its location near vital structures and difficulty of early detection. The majority of NPC tumors are non-keratinizing squamous cell carcinomas that are associated with Epstein-Barr virus. Risk factors include EBV infection, diet, and genetic predisposition. Radiation therapy is the primary treatment, while surgery has a limited role. Prognostic factors like tumor size and lymph node involvement affect survival rates. Angiofibromas are benign nasopharyngeal tumors that mainly affect young males and are treated surgically. Oropharyngeal cancers are usually squamous cell carcinomas associated with alcohol and tobacco use. Treatment involves surgery,
Sinunasal malignacy
This document discusses sinonasal tumours, including:
1. It classifies sinonasal tumours by tissue of origin such as epithelial, neuroendocrine, soft tissue, bone, etc. and lists examples of benign and malignant lesions within each tissue.
2. It provides details on specific benign tumours such as inverted papilloma, haemangioma, and juvenile angiofibroma.
3. It also discusses malignant tumours of the sinonasal region like squamous cell carcinoma, adenocarcinoma, olfactory neuroblastoma and haemangiopericytoma.
Oral squamous cell carcinoma
This document discusses oral squamous cell carcinoma, including its definition, risk factors, signs and symptoms, diagnosis, treatment, and prevention. Key points:
- It is a malignant neoplasm of the oral cavity epithelium capable of local growth and metastasis. Major risk factors include tobacco use, alcohol consumption, and HPV infection.
- Common symptoms are non-healing sores, lumps, pain or difficulty swallowing. Diagnosis involves biopsy and imaging tests. Treatment options are surgery, radiation, chemotherapy and rehabilitation.
- Prevention focuses on reducing risk factors through health education and discouraging behaviors like smoking, as well as early detection through screening to find cancer at earlier, more treatable stages.
Head and neck cancer Dr VIPIN V NAIR
This document discusses head and neck cancers, their classification, and risk factors. It covers:
1) The TNM staging system for head and neck cancers, which classifies tumors based on their size (T), lymph node involvement (N), and distant metastasis (M). Higher stages indicate larger tumors, greater node involvement, or presence of metastasis.
2) The many risk factors for head and neck cancers, including tobacco use, alcohol consumption, HPV infection, poor oral hygiene, genetic conditions, and others. Tobacco is implicated in over 90% of cases.
3) Common signs and symptoms of head and neck cancers, which are often not apparent until the disease has advanced. Symptoms include lumps
Pharyngeal tumor
The document discusses tumors of the pharynx, including anatomy, histology, risk factors, types, diagnosis, staging, and treatment. The pharynx is divided into nasopharynx, oropharynx, and hypopharynx. Common pharyngeal cancers include squamous cell carcinoma and nasopharyngeal carcinoma. Risk factors include smoking, alcohol, radiation exposure, and viruses. Diagnosis involves medical history, examination, and imaging tests. Treatment depends on cancer type and stage but may include surgery, radiation therapy, or chemoradiation.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
