Department of Pathology and Otolaryngology, Loyola University Medical Center, Maywood, Illinois 60153.

Published: September 1988

A case of Merkel cell (trabecular) carcinoma metastatic to the parotid gland and diagnosed clinically by fine needle aspiration cytology is described. The primary tumor was on the left upper eyelid and had been resected four months earlier. This unusual presentation and the incidence of secondary tumors involving the parotid gland are discussed.

Background: Different parotid tumors differ in terms of treatment strategies due to their distinct biological behaviors. Time-dependent diffusion magnetic resonance imaging (t-dMRI) can characterize and quantify the cytological indexes, and then aid the differential diagnosis of various tumors. However, the value of t-dMRI in the analysis of parotid gland tumors remains unclear.

Frey syndrome is a late complication after parotidectomy and represents an aberrant regeneration of the auricular nerve after its damage. The degree of manifestation can vary from minor hyperemia to the inability to eat in public places. As it turned out, the etiology of this syndrome is much broader than we might have assumed, as evidenced by the data of domestic and foreign literature.

Various approaches and techniques have been developed to address parotid neoplasms over the years. This article reflects on the integration, modification, and refinement of these techniques over a decade of clinical practice. This article provides a narrative description of the evolution of a head and neck oncologic surgeon's approach to parotid neoplasms.

Objective: A nanometer-sized vesicles originating from bone marrow mesenchymal stem cells (BMMSCs), called exosomes, have been extensively recognized. This study defines the impact of BMMSCs and their derived exosomes on proliferation, apoptosis and oxidative stress (OS) levels of CP-induced parotid salivary gland damage.

Methods: BMMSCs were isolated from the tibia of four white albino rats and further characterized by flowcytometric analysis.
