A retrospective study of 1000 cases of microscopically diagnosed head and neck cancers in the University Hospital, Kuala Lumpur was done. Head and neck neoplasms comprise 7.1% of all tumours diagnosed in this Hospital and the commonest sites of involvement are the nasopharynx (29.1%), cervical lymph nodes (22.6%), oral cavity (10.2%), thyroid (8.2%) and skin (6.5%). Histologically, 87% of tumou...

Small cell neuroendocrine carcinoma, also known as oat cell carcinoma is a frequently encountered bronchogenic neoplasm. Neuroendocrine carcinomas of the head and neck are rare aggressive tumors and pose a diagnostic and management challenge. Differentiation from conventional nasopharyngeal carcinoma is difficult due to morphological characteristics and small biopsy specimen. Distinguishing is ...

COMPLICATIONS DEFINITION Benign, biologically progressive, highly vascular, high incidence of persistence and recurrence. 0.5% of all neoplasms of head and neck. Hippocrates described a polyp in the nose which weeped blood. Finally Friedberg in 1940 used the term Angiofibroma. Sphenopalatine foramen (Usually Superior lip of the sphenopalatine foramen at the junction of the Pterygoid Process of ...

BACKGROUND Occupational exposure to formaldehyde has been associated with excess risk of nasopharyngeal and selected other cancers. PATIENTS AND METHODS We reviewed and pooled the results of cohort studies published through February 2007. RESULTS There were 5651 deaths from all cancers observed in six cohorts of industry workers and six of professionals, with a pooled relative risk (RR) of ...

introduction: nasopharyngeal carcinoma is one of the most common malignancies in the head and neck region and radiotherapy is its treatment of choice. in spite of the fact that it is widely used, due to the presence of many sensitive organs or tissues in this region, patients may suffer from a wide range of side effects. one such sensitive tissue is the spinal cord. if the absorbed dose to spin...

undifferentiated nasopharyngeal corcinoma is frequently misdiagnosed as large cell malignant lymphoma. the aim of this study is to evaluate the diagnostic role of immunohistochemistry and electron microscopy in this tumor. 81 cases of nasopharyngeal carcinoma were studied. patients ranged from 9-90 years in age (mean: 48.5 years). the age incidence curve was bimodal with two peaks in 2-3 and 5-...

Pediatric nasopharyngeal tumors are rare, and few clinicians possess more than anecdotal experience. The differential diagnosis includes a diverse group of benign and malignant tumors, but can be narrowed further based on the clinical and radiographic appearance of the mass. Nasopharyngeal angiofibroma has such characteristic angiographic and CT imaging that many authors suggest biopsy is not e...

Sinonasal tract malignancies are uncommon, representing no more than 5% of all head and neck neoplasms. However, in contrast to other head and neck sites, a significant proportion of sinonasal neoplasms tend to display a poorly/ undifferentiated significantly overlapping morphology and a highly aggressive clinical course, despite being of diverse histogenetic and molecular pathogenesis. The wid...

The nasopharynx is an unusual site for extraosseous chordoma. The characteristic histology and immunohistochemistry confirmed the diagnosis. The behaviour of this tumour is locally aggressive. We report a case of nasopharyngeal chordoma in an elderly patient with literature review.
