Salivary gland tumors are uncommon, the world wide annual incidence of salivary gland tumors ranges from 0.4 to 13.5 cases per 100 000 population (Auclair et al., 1991). Tumors of salivary glands account for 2% to 6.5 % of head and neck neoplasms and 21% to 46% are malignant (Ellis & Auclair, 1996). In Bangkok, during the period 2001-2003, the estimated age standardized incidence rate of saliva...

Despite remarkable advancements in medicine, cancers remain one of the most challenging pathologies for doctors. Head and neck neoplasms especially raise serious management problems due to the often advanced stage at the moment of diagnosis, associated with difficult curative interventions that impose significant changes in the quality of life of patients. Whenever possible, a complete removal ...

Glomus tumors were described by Rosenwasser in 1945 (1). Glomus body tumors, often abbreviated as glomus tumors, are also known as paragangliomas or chemodectomas. They are a family of benign hypervascular neoplasms arising from the chief cells of the paraganglionic tissues. Furthermore, glomus tumors have vascular structure, comprising cell bundles stained with non chromaffin among thin-walled...

Salivary gland neoplasms are a rare group of tumors; the annual incidence rate is 1 in 100,000 individual, comprising about 3% of all head and neck neoplasms [4]. The mean age of patients with salivary gland tumors is 45 years, peaking in the sixth and seventh decades of life. Benign salivary gland tumors occur more frequently in females, while malignant tumors are slightly more frequent in mal...

INTRODUCTION The kidney is the third primary infraclavicular localization of malignant neoplasms metastasizing to the head and neck. The objective of this paper is to analyze the clinical presentation, diagnostic difficulties, management and outcome of metastatic renal cell carcinoma to the head and neck. MATERIAL AND METHODS Retrospective review of four patients with renal cell carcinoma who...

BACKGROUNDS/AIMS With development of imaging techniques, pancreatic tumors are being diagnosed more frequently. Applying the standard surgical procedures for pancreatic head tumors, such as pancreaticoduodenectomy and pylorus-preserving pancreaticoduodenectomy may seem too extensive for benign or low-grade malignant pancreas head tumors. Duodenum-preserving pancreatic head resection (DPPHR) has...

termittent epigastric pain and nausea. Her hemoglobin concentration was 10.3 g/dL. Abdominal imaging revealed a 4−cm cystic mass in the pancreatic head (l" Figure 1). ERCP showed an ulcerated polypoid mass at the minor duodenal pa− pilla (l" Figure 2). Cannulation of the nor− mal−appearing major papilla showed a dilated, 4−mm main pancreatic duct and a stricture of the main duct in the head of ...

Salivary gland tumours are estimated to represent approximately 3% of all head and neck tumours. About 70-80% of these neoplasms occur in the major salivary glands, with the parotid gland being the most commonly affected site. The metastasizing pleomorphic adenoma (MPA) has histological characteristics of pleomorphic adenoma, but it has the capacity to generate local recurrences and distant met...

Extraskeletal myxoid chondrosarcoma (EMC) is a malignant soft-tissue neoplasm rarely described in the head and neck region of children and adolescents. We describe a case of EMC affecting the masticator space and a literature review. A 13-year-old boy who presented a large painless, diffuse mass causing progressive midfacial asymmetry of 6 months duration. Histopathological evaluation revealed ...

Introduction. Rhabdomyomas of the head and neck are exceptionally rare benign mesenchymal tumors. Rare cases have been reported to involve other sites of the body including the head and neck regions. Case Presentation. We report a case of voluminous extracardiac adult rhabdomyoma affecting adult patients and initially seen as slowly growing, indolent neoplasms. The patient is a seventy-year old...
