BACKGROUND: Solitary extramedullary plasmacytoma of the parotid gland is a rare condition. Intracytoplasmic Crystalline inclusions in the tumor are even rarer and have been reported only once in the parotid gland. CASE PRESENTATION: We report here, a case of plasmacytoma of the parotid gland with intracellular crystalline inclusions in a 73-year-old woman CONCLUSION: Solitary extramedullary pla...

INTRODUCTION Atheroma of the facial artery is an extremely rare disease. CLINICAL FINDINGS/PATIENT CONCERNS Herein, we report an extremely rare case of an atheroma arising from the facial artery, mimicking a parotid gland tumor. DIAGNOSES The preoperative diagnosis was a right-sided parotid gland tumor. INTERVENTIONS We performed removal of the right parotid gland tumor, via a modified fa...

PURPOSE This study was conducted to explore the differences in salivary microRNA (miRNA) profiles between patients with malignant or benign parotid gland tumors as a potential preoperative diagnostic tool of tumors in the salivary glands. EXPERIMENTAL DESIGN Whole saliva samples from patients with malignant (n = 38) or benign (n = 29) parotid gland tumors were obtained from the Salivary Gland...

RATIONALE Among the nontuberculous mycobacteria, Mycobacterium abscessus is a common cause of skin, soft tissue, and bone infections. However, disseminated M. abscessus infection that mimics cancer metastasis with an underlying relatively immunocompetent condition has rarely been reported. PATIENT CONCERNS A nonsmoking 73-year-old man with an underlying relatively immunocompetent condition re...

Parotid gland or duct injury can be caused by assault with a knife, bottle, or more rarely, gunshot. Post-traumatic parotid gland and duct injuries are not common.The low rate of occurence of parotid injury may account for the missed diagnosis of parotid and duct injury on admission and, after a varying period, sialoceles or fistulas. This report describes a case of a post-traumatic sialocele o...

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...

Overall salivary gland tumours are rare, comprising of less than 3% of overall head and neck neoplasms. Parotid gland is the most common site for the benign salivary gland neoplasm. Usually they are painless slow growing lesion involving the superficial or deep part of the gland and can severely affect the facial nerve functioning. Treatment mainly comprises of surgical excision with preservati...

The major salivary glands consist of the parotid, the submandibular, and the sublingual glands. Under the control of the parasympathetic nervous system, the major salivary glands are responsible for the principal portion of saliva produced, which can be as much as 1.5 liters per day. The minor salivary glands of the oral cavity, pharynx, and upper airways contribute only a small percentage of t...

Previous reports suggested that there is no significant difference in the binding affinity of pilocarpine and cevimeline on muscarinic receptors (1). However, in vivo studies from our laboratory suggested that pilocarpine-induced salivation from the parotid gland is greater than that induced by cevimeline in rats. Therefore, in the present study, sialogogue-induced intracellular Ca(2+) mobiliza...
