Nicotine has been reported to increase the intracellular Ca(2+) concentration ([Ca(2+)](i)) in sublingual acini due to neurotransmitter release from nerve terminals associated with the cell preparation (1). However, it is unclear whether or not the same reaction exists in parotid cells. Therefore, we investigated effect of nicotine on Ca(2+) mobilization in digested parotid acini from rats. Aft...

  Tannins are plant-derived polyphenolic compounds that are widely found in foods, particularly in fruits and beverages. These materials are water-soluble and able to precipitate proteins from aqueous solutions. It had been shown that feeding some animals such as rat and mouse with tannins mimicks the effects of isoproterenol on salivary glands. Tannins stimulate β-receptors by some indirect me...

Lipoma rarely involves parotid gland especially in children. An 11-year-old boy presented with right parotid swelling. Preoperative workup including CT scan and FNAC gave suspicion of parotid gland lipoma. The diagnosis was confirmed on histopathology after complete excision of the mass.

A 67-year-old male with three synchronous tumors in the unilateral parotid gland is reported. Postoperative histological examinations confirmed the presence of three synchronous primary tumors, specifically pleomorphic adenoma, Warthin's tumor and salivary duct carcinoma, in the right parotid gland. To our knowledge, this is the first case report describing three different histological types in...

Blunt trauma to the parotid gland is extremely rare and requires considerable force. We present a unique case in which a child sustained parotid injury without any associated injury to the facial skeleton, parotid gland and ductal structures and managed successfully. A literature search revealed that this type of injury has not been reported previously.

Parotid swelling is a common presentation in ENT clinic. Most of the cases involve pathology of the gland. There are not many reported cases about parotid duct pathology. We describe a case of a large parotid duct mucocele with a calculus. Excision of the mucocele and superficial parotidectomy was performed. The post-operative recovery was uneventful.

OBJECTIVE Assessment of benign and malignant lesions of the parotid gland, including metastatic lesions, is challenging with current imaging methods. Fluorine-18 FDG PET/CT is a noninvasive imaging modality that provides both anatomic and metabolic information. Semiquantitative data obtained from PET/CT, also known as PET/CT parameters, are maximum, mean, or peak standardized uptake values (SUV...

Background Lipoblastomas are rare benign neoplasms that arise from fetal white fat cells. They are typically found in children under the age of 3 and have been reported in the mediastinum, extremities, and infrequently in the head and neck. We present a rare case of a lipoblastoma arising from the parotid gland and the first known report of a parotid lipoblastoma in a teenager. Case presentat...

Toxoplasmosis manifesting as a parotid mass is rare; our review of the literature found only 6 previously reported cases. We report 2 new cases. Both patients presented with a small, mobile left parotid mass, and both were successfully treated with a diagnostic superficial parotidectomy. In both cases, the patient had been regularly exposed to cats and had recently eaten undercooked meat. When ...
