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...

Acinic cell carcinoma is an uncommon low-grade malignant tumor of salivary glands. It was first described by Nasse in 1892, arising in parotid salivary gland. Salivary gland tumors are also known to develop within jaw bones, arising within the jaw as a primary central lesion, and are extremely rare with only a few cases reported. We present a rare case report of 65-year-old woman with intraosse...

Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...

It has been reported that cimetidine, a histamine type-2 receptor (H2R) antagonist, inhibits the growth of glandular tumors such as colorectal cancer. However, its effects against salivary gland tumors are still unknown. We demonstrated previously that human salivary gland tumor (HSG) cells spontaneously express the neural cell adhesion molecule (NCAM) and also that HSG cell proliferation could...

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...

hyalinizying clear cell carcinoma is a rare tumor which affects women more than men and is more common in minor salivary glands. the purpose of this paper was to describe a case of hyalinizing clear cell carcinoma of buccal vestibule in a 55-year-old woman. it is important to differentiate this neoplasm from other tumors with clear cell features because of their differences in treatment and cli...

PURPOSE OF REVIEW The goal of this article is to offer an update on the treatment and prognosis of the most common epithelial tumors of the lacrimal gland, report on new pathological entities and offer a review of the classification of lacrimal gland tumors. RECENT FINDINGS Improvements have been made in the understanding of lacrimal gland lesions with the knowledge that lacrimal gland tumors...

Salivary gland tumors are uncommon and constitute a highly heterogeneous histopathological group of neoplasms. The present study aims to determine the correlation between cytological findings parotid tumors, preservation facial posterior branch greater auricular nerve during surgery. A 21 cases was conducted at our hospital- GMERS Medical College Civil Hospital, Valsad. All them were clinically...

twenty five cases of minor saliva ry glands tumors which was observedat the department of pathology of university of tehran from 1967 to 1972 are presented and discussed . benign mixed tumor is the most common and the only benign lesion in this series of 75 patient with intraoral salivary gland tumor. there were eleven malignant type and hence about 44% of all the tumor arc malignant and it cor...

Background and aims. Mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. The distribution and significance of mast cells in many tumors have been demonstrated. However, few studies have evaluated mast cell infiltration in salivary gland tumors. In this study, mast cell counts were evaluated in benign and malig-nant salivary gland tumors. Ma...
