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...

introduction: mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.however, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the english-language literature since it was discovered in 1987. case report: herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, as...

In minor gland, it more palate. lip rare tumour. Thus, we present case pleomorphic originating from upper 75 years old male patient. The tumor was completely excised and sent for histopathological examination which showed micro...

in this study ten pairs of superior gland of third eyelid of 10 adult male camels free of apparent ocular disease were examined to compare the normal anatomical and histological properties of these glands. after dissecting, all of the glands were characterized and measured (length and width) on both the left and right side. in the camels, the superior gland of the third eyelid was oval shaped a...

conclusions a complete immunohistochemical study should be considered in cases of malignant salivary gland tumors. to reduce the recurrence rate of these tumors, the optimum therapies are radiotherapy and chemotherapy. introduction salivary gland tumors are rare head and neck lesions. the majority are benign, with only 20% of cases malignant. an epithelial-myoepithelial carcinoma is a rare low-...

Introduction: Laryngeal squamous cell carcinoma (SCC) can invade the thyroid gland leading to unnecessary thyroidectomies with subsequent hypothyroidism and hyperparathyroidism. Thus, clinicopathological variables should be defined in order to predict thyroid gland invasion preoperatively.   Materials and Methods: We performed a retrospective analysis of 1,465 patients with laryngeal SCC referr...

introduction: chronic sclerosing sialadenitis is a relatively uncommon disorder of the salivary gland. because of its clinical similarity to a salivary gland neoplasm, this condition has been known as kuttner tumor and is classified as a tumorlike lesion. case report: this is the first reported case of bilateral kuttner tumor of the submandibular glands in iran. it was initially diagnosed as a ...
