INTRODUCTION Salivary gland neoplasms represent the diverse group of tumours encountered by the head and neck surgeons. MATERIAL AND METHODS The study is analysis of 531 patients with parotid gland tumours in patients treated in ENT Department during 1986-2006. We analysed surgical treatment and intraoperative tumour stage. The results of histological diagnosis were presented. RESULTS The f...
Cystadenoma and cystadenocarcinoma of the salivary glands are rare tumors, approximately half of cases being diagnosed at the level of parotid. The studied tumor associated both benign and malign zones, with deep infiltrating character in the adjacent structures. In both areas the growing pattern was predominantly cystic and papillary, and the proliferated neoplastic cells were majority cubical...
Basal cell adenocarcinoma (BCAC), the malignant counterpart of basal cell adenoma, is a rare salivary gland neoplasm, the most common site being parotid gland. It has been classified as a low-grade tumor with a favourable prognosis. Only a few cases have been reported to occur in submandibular gland. This report describes a case of right submandibular swelling which was diagnosed as a vascular ...
Papillary cystadenocarcinoma is an extremely rare malignant tumor of the salivary glands. Major locations of this neoplasm are the parotid gland, sublingual gland, and minor salivary glands, while occurrence in the submandibular gland is extremely rare. Magnetic resonance imaging (MRI) findings of this lesion have not been reported in the literature. Herein, we present a case of papillary cysta...
Epithelial – Myoepithelial Carcinoma (EMC) is a rare malignant salivary gland neoplasm that most commonly occurs in the Parotid gland, but can also arise in the Minor Salivary Glands. EMC of the maxillary sinus extremely rare. We describe here a case of a 74-year-old patient who presented with maxillary swelling for 4months and nasal discharge for 3 months. Computed Tomography Scan revealed an ...
alivary gland carcinosarcoma is an exceedingly rare and ggressive neoplasm composed of a mixture of carcinomaous and sarcomatous components, with either component apable of metastasis. Salivary gland carcinosarcoma can rise in pleomorphic adenoma (PA) or de novo.1 The present study reports a case of the parotid gland de ovo carcinosarcoma, which contained salivary duct adenoarcinoma and sarcoma...
Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is...
Salivary duct carcinoma (SDC) is an uncommon, aggressive tumour, which carries a poor prognosis. SDC affects the major salivary glands, usually occurring in the parotid gland. A 76-year-old male patient presented with right-sided nasal obstruction and rhinorrhoea. A polypoidal mass was seen in the right inferior turbinate mimicking a benign neoplasm. Histological examination following wide exci...
Epithelial myoepithelial carcinoma is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. We report a case of primary epithelial myoepithelial carcinoma of submandibular salivary gland in a 65 year old female who presented with left cheek swelling of six months duration. CT scan revealed a localized subma...
Salivary duct carcinoma is a rare and highly aggressive malignant neoplasm that frequently metastasises to other organs, but cutaneous metastasis is uncommon. There are only 6 cases reported in the literature with metastases to the skin and in all cases the tumour originates from the parotid gland. We present a case of skin metastases from the submandibular gland that was mistaken for basal cel...
