The Clinco-pathological, immunohistochemical and molecular findings of four cases of Mammary Analogue Secretory Carcinoma (MASC) of salivary glands found in Mexico are described. The cases were extracted from 253 salivary gland tumors from a single institution in Mexico City. The 85 Candidates for initial selection were: low grade mucoepidermoid carcinoma (MEC) (N=70 ), Acinic cell cancinoma (A...

The occurrence of lymphoepithelial carcinoma in the oral cavity is extremely rare and a case with involvement of minor salivary glands is very uncommon. We describe a case of LELC of the oral cavity with involvement of the upper lip and of minor salivary glands. The tumour was described at the clinical and instrumental level; moreover, its histopathological phenotype was defined. Finally, the p...

Adenoid cystic carcinoma most often presents a diagnostic and treatment challenge owing to the rarity of occurrence. Most findings reported in literature about adenoid cystic carcinoma are actually based upon studies of small number of patients and there is a dire need for further studies regarding its clinical behavior, treatment modalities and prognosis.

The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to radiation at dose 15Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

Introduction The incidence of salivary gland tumors is claimed to be influenced by geographical and racial factors; however there is no epidemiological study of salivary gland tumors in Maharaj Nakorn Chiang Mai Hospital, Thailand. Objective To study the frequency of salivary gland tumors in Maharaj Nakorn Chiang Mai Hospital, Thailand. Materials and methods The histological diagnoses of 198 sa...

A case of hyalinizing clear cell carcinoma (HCCC) of the minor salivary glands of the oral cavity is reported. A 52- year-old woman presented with a growing mass at the base of the tongue. The patient underwent complete resection of the tumour. The histological picture was characterized by trabeculae or solid nests of proliferating cells with a clear cytoplasm, surrounded by a hyalinizing strom...

IgG4-related disease has been recently defined as a distinct clinic-pathologic entity, characterized by dense IgG-4 plasmacytic infiltration of diverse organs, fibrosis, and tumefactive lesions. Salivary and lacrimal glands are a target of this disease and, when affected, may clinically resemble Küttner tumor, Mikulicz disease, or orbital inflammatory pseudotumor. In some patients, the disease ...

OBJECTIVE To delineate the spectrum of salivary gland tumors in our setup. SETTING The Aga Khan University Medical Centre, Karachi. METHOD Tumors were analysed considering histological type, age and sex of the patients and anatomic location. The diagnosis of individual tumours was based on the 1991 World Health Organisation Classification. RESULTS During the span of eight years (1991-1998...

Estrogen receptors (ERs) expression has been studied in salivary gland tumors, however, there are conflicting results regarding its expression in the literatures. The aim of this study was to investigate the expression of estrogen receptors protein (ERs) in pleomorphic adenoma (PA) and mucoepidermoid carcinoma (MEC) of salivary glands using immunohistochemistry. 35 cases of intraoral minor sali...

Adenocarcinoma is relatively less common on the tongue.[1] Polymorphous low‐grade adenocarcinoma (PLGA) is a malignant tumor of minor salivary glands which is slow growing and carries a low metastatic potential. Histologically, PLGA exhibits a spectrum of growth patterns such as cribriform, tubular, trabecular, fascicular and solid structures. Concentric whorls forming target‐like patterns are ...
