Background and objectives: Salivary gland tumours account for 2-6.5% of all the neoplasms of the head and neck. Fine needle aspiration cytology (FNAC) is being increasingly used in the diagnosis of salivary gland tumours. The objective of this study was to evaluate the diagnostic accuracy and the sensitivity and specificity of FNAC in various salivary gland tumours in correlation with their his...

Soft tissue sarcomas are malignant extraskeletal tumors of mesenchymal origin and uncommon in children.1,2 Rhabdomyosarcoma is most common and constitutes about 10 to 15% of the malignant neoplasms affecting children. The tumor is located with a high incidence in the head and neck region followed by the extremities and perineal region. We recently encountered one such interesting case of intrao...

Schwannomas or neurilemmomas are benign neoplasms of the Schwann cells in neural sheaths. They may arise in any nerve in the body and occur frequently in the head and neck region or extremities. While breast lumps and schwannomas are very common, mammary schwannomas are exceedingly scarce with ,30 cases reported in the literature. We describe a case of a breast schwannoma in a 37-year-old femal...

Juvenile nasopharyngeal angiofibroma (JNA) constitutes less than 0.5% of all head and neck neoplasms. It is a histopathologically benign, yet locally agressive, vascular tumor that occurs most frequently in males from 5 to 25 years. Advances in imaging and treatment techniques are now facilitated more accurate staging of this disease. In this study, we present a case of JNA, to whom pre-operati...

Little is known regarding the molecular genetic events in head and neck carcinoma. Epidemiological evidence suggests that both alcohol and tobacco use are related to the development of these neoplasms, and viral infections have also been postulated to play a role in some tumors. Loss of p53 tumor suppressor gene function has been found in many malignancies and can occur through either gene muta...

  Thymoma is a term that should be restricted to neoplasms of thymic epithelial cells, irrespective of the presence or the number of lymphocytes. The usual location of thymoma is the antrosuperior mediastinum; however, this tumor can also occur in other mediastinal compartments, in the neck, within the thyroid gland, in the pericardial cavity, the pulmonary hilum, within the lung parenchyma, o...

Objective(s): Functional imaging presents a non-invasive process that may capture the hyper-metabolic nature of red bone marrow in myeloproliferative neoplasms, such as polycythemia vera (PV). Methods: This study analyzed the FDG-PET/CT scans (n=12) of six patients diagnosed with PV and six age-sex matched controls using a quantitative global analysis methodol...

Introduction: Hamartomas is a neoplasms composed of mature tissue elements from the affected site with disproportion between their components. Although lingual hamartomas are traditionally infrequent in the head and neck, a significant number of case reports with this disorder in infancy are arising from the literature.   Case Report:</em...
