Salivary gland tumours are relatively uncommon and most of the tumours arise from parotid gland. Fine needle aspiration cytology (FNAC) is advised preoperatively as diagnostic tool but sometimes found to shown both false positive and false negative results. This study was aimed to find out distribution of neoplasm of major salivary glands and also to explore the sensitivity and specificity of F...
Epithelial-myoepithelial carcinoma (EMC) is considered as a rare malignant salivary gland neoplasm with good prognosis, low recurrence rate and rare metastasis. Here we present a case of epithelial-myoepithelial carcinoma in a 42-year-old female with a swelling of 3-year duration in her palate. Histopathologic evaluation of the lesion demonstrated a well-circumscribed, biphasic salivary gland t...
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...
Polymorphous adenocarcinoma is a slow growing malignant tumor of minor salivary glands. The most common location these tumors palate, buccal mucosa, upper lip, floor mouth and retromolar region. This neoplasm characterized by cytological uniformity, architectural diversity infiltrative growth pattern. case report polymorphous occurring in lacrimal gland. They are seldom reported this propose un...
Sialolipoma is a recently described histologic variant of lipoma and is characterized by well-demarcated proliferation of mature adipocytes with secondary entrapment of salivary gland elements. These tumors have been observed in both the major and minor salivary glands, with more than 20 cases being reported in the English literature. In general, the clinical presentation of sialolipomas of the...
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...
BACKGROUND Primary ductal adenocarcinomas of the lacrimal gland are very rare. This neoplasm shares some histological and immunohistochemical similarities with salivary duct carcinoma. CASE PRESENTATION Here, we present a case of a 55-year-old Moroccan man with lacrimal gland adenocarcinoma. He underwent orbital exenteration with lymph nodes dissection and ipsilateral parotidectomy. After sur...
Introduction: Salivary gland Fine Needle Aspiration Cytology is a well-established pre-operative diagnostic tool done routinely worldwide. Heterogeneity of salivary lesions makes cytology diagnosis challenging for most cytopathologists. Milan system reporting six tier developed to minimize inter-observer variability, thus enhance reproducibility cyto-diagnosis.
 Aims: To study utility Syst...
Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and women are usually more frequently diagnosed than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. A slowly enlarging...
Epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here a case of 58-year-old female presented with left cheek swelling of one-year duration. CT scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. Histological examin...
