Nine cases of central salivary gland tumors of the jaws were seen during the period 1962-1968. Four patients were in the sixth decade; they all presented with swelling of one of the jaws. Pain was unusual. X-ray of the mandible revealed either a diffuse rarefaction or a multiloculated cystic appearance. Four patients had a cylindroma, 3 had mucoepidermoid carcinoma, and 2 had an adenocarcinoma....

INTRODUCTION A retrospective study of melanocytic naevi was undertaken to assess the degree of clinico-pathological correlation and incidence of histological atypia. MATERIALS AND METHODS The case records from January to March 1996 of all patients with histologically diagnosed melanocytic naevi at the National Skin Centre were analysed. RESULTS Of the 240 lesions removed from 167 patients, ...

Collagenous spherulosis (CS) is an incidental finding that usually occurs in association with benign proliferative and preinvasive lesions. Adenomyoepithelioma is a biphasic neoplasm of the breast, composed of both luminal epithelial and myoepithelial cells. Despite the common epimyoepithelial histogenesis, CS has never been described in association with adenomyoepithelioma. This report describ...

Adenoid cystic carcinoma also known as cylindroma is a rare tumor, accounting for only 1% of all malignant tumors of the oral and maxillofacial region. It accounts for 22% of all salivary gland malignancies and involves both major and minor salivary glands but the percentage for involvement of minor salivary gland is more than that of major salivary glands. 1 It is a slow growing tumor and is o...

Adenoid cystic carcinoma, also called cylindroma, is the second most common histological type of tracheal malignancy but represents 1% of all respiratory tract cancers. We report a case of a 59-year-old patient submitted to an incomplete resection of the trachea and subsequently treated with adjuvant tomotherapy. There have been no reports in the literature regarding intensity-modulated radiati...

We compared 4 breast cylindromas with 50 dermal cylindromas and 8 adenoid cystic breast carcinomas. Except for a modest increase in the number of eccrine ducts and reactive Langerhans cells in dermal cylindromas, breast and dermal cylindromas showed identical histologic and immunohistochemical features. Both were characterized by epithelial islands containing central basaloid cells and peripher...

BACKGROUND Tracheal malignancies are usual victim of delay in diagnosis by virtue of their symptoms resembling asthma. Sometimes delayed diagnosis may lead to almost total airway obstruction. For difficult airways, not leaving any possibility of manipulation into neck region or endoscopic intervention, femorofemoral cardiopulmonary bypass can be a promising approach. CASE PRESENTATION We are ...
