Palatal Presentation of Para-Pharyngeal Mass

Para-pharyngeal space tumors showed a varied presentation and through a great challenge to the surgeon in respect to pre-operative evaluation as well as surgical approach. Para-pharyngeal space (PPS) is an inverted cone-shaped potential space that extends from the hyoid bone to the base of the skull.It is filled with fat and areolar tissue lie laterally on either sides of pharynx; and is bounded and subdivided by various condensations of fascia1 . Tumors, although rare less than1% of head neck neoplasm can arise from any structures of this space. Mostly they are benign70-80% and 20-30% are malignant. Salivary gland tumor, particularly deep lobe parotid constitutesmore than 80%2,3. Imaging studies are invaluable to define the site of origin, extension, relationship to the great vessels of the neck and other neurovascular structures4 . Surgery is the mainstay of treatment. Several approaches have been discussed in the text books. We present a case of a huge parapharyngeal space tumor that was excised completely through trans-cervical approach without any morbidly

Pattern of Major Salivary Gland Malignancy in B.P. Koirala Memorial Cancer Hospital

Background: Salivary gland tumors represent a different variety of histological types. The definite diagnosis of type of salivary gland tumor is required for proper treatment planning. The aim of this study was to evaluate the pattern of salivary gland malignancy in B.P. Koirala Memorial Cancer Hospital, Bharatpur, Chitwan. Methods: This cross-sectional study was carried out in patients of malignant salivary gland tumor registered in B.P. Koirala Memorial Cancer hospital retrospectively from September 2009 to August 2012. Results: Parotid gland was the most common sites for malignant salivary gland tumor (80%) followed by submandibular gland (20%). Mucoepidermoid carcinoma is the most common malignant salivary gland tumor of parotid gland and Adenoid cystic carcinoma was the most common malignant tumor of submandibu-lar gland. Male: Female ratio was 1.5:1 with age range from 12 years to 71 years. Common age group for malignant salivary gland tumor was from 50 to 60 years. Conclusions: Parotid was the most common site whereas Mucoepidermoid carcinoma was the most common malignant tumor of major salivary gland.

Low Grade Central Mucoepidermoid Carcinoma

ABSTRACT Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor, comprising about 15% of all salivary gland tumors and 30% of all salivary malignancies. Most of the MEC arise in the parotid gland. Rarely, it originates in the mandible and maxilla as an intraosseous variant, referred to as ‘central mucoepidermoid carcinoma’ or ‘intraosseous mucoepidermoid carcinoma’. Central mucoepidermoid carcinomas (CMECs) are extremely rare, but well-known entity, comprising 2 to 3% of all MECs reported. Histopathologically, this malignant neoplasm is characterized by mucous, intermediate and epidermoid cells. In this report, we present a case of a male patient diagnosed as low grade CMEC.
