Lipoma is a common benign tumor affecting the soft tissues arising in every location where fat is normally present. About 15% of lipomas occur in head and neck region. The lipoma of parotid gland is a rare entity, comprising 0.6% 4.4% of all parotid tumors. The etiology remains unclear. The case described a lipoma of the superficial lobe of the parotid gland in a 46-year-old male.

Abstract A 14-year-old boy presented with left preauricular painless swelling of 10 months' duration. Local examination revealed a 3 × 2-cm, firm, nodular, nonmobile mass in the area, just front tragus. Fine needle aspiration yielded paucicellular smears comprising singly scattered histiocyte/myofibroblast-like spindle cells and occasional giant cells. It was reported as benign mesenchymal lesi...

DOI: 10.1590/S1679-45082015AI3096 A 10-year-old girl presented with a painless, slow-growing swelling on left pre-auricular region that was noticed for 2 years (Figure 1). The swelling was bosselated, nontender, firm-to-hard on palpation, had poorly-defined margin, and measured approximately 3.5cm x 3.0cm. In addition, it had restricted mobility, and seemed to be of parotid origin, with overlyi...

Warthin tumor (WT) owing to its heterogeneous appearance, biological behavior and multicentricity poses a diagnostic challenge to cytologists worldwide. We report a rare double pathology of mucoepidermoid carcinoma (MEC) with WT which was diagnosed by fine needle aspiration (FNA). Cytological smears revealed sheets of epithelial cells and small clusters of squamous cells in a background of muco...

abstract we report a 30 year old woman who presented with a painless preauricular mass of two months duration. superficial parotidectomy was performed for the patient. histological examination and immunohistochemical findings were in favor of mixed cellularity hodgkin’s lymphoma (mchd). according to this diagnosis the patient received local radiotherapy and during 4 months of follow-up no recur...

OBJECTIVES/HYPOTHESIS To determine clinical and pathological correlates of outcome among patients treated by surgery and postoperative radiation therapy for mucoepidermoid carcinoma of the parotid gland. STUDY DESIGN Retrospective review. METHODS The medical records of 61 patients treated by surgery and postoperative radiation therapy for localized mucoepidermoid carcinoma of the parotid gl...

BACKGROUND We evaluated the use of intraoperative fluorescence guidance by enzymatically cleavable ratiometric activatable cell-penetrating peptide (RACPPPLGC(Me)AG) containing Cy5 as a fluorescent donor and Cy7 as a fluorescent acceptor for salivary gland cancer surgery in a mouse model. METHODS Surgical resection of small parotid gland cancers in mice was performed with fluorescence guidanc...

The more common causes of parotid enlargement in children are infections and inflammatory conditions. Primary neoplasms of the parotid glands are rare in pediatric age group; however, secondary malignancies have been reported in survivors of childhood leukemia. The parotid glands have been the sites of relapses in acute lymphoblastic leukemia (ALL) and acute myeloid leukemia. However, bilateral...

Handheld mobile phones were introduced in Denmark and Sweden during the late 1980s. This makes the Danish and Swedish populations suitable for a study aimed at testing the hypothesis that long-term mobile phone use increases the risk of parotid gland tumors. In this population-based case-control study, the authors identified all cases aged 20-69 years diagnosed with parotid gland tumor during 2...

BACKGROUND Radiation-induced parotid damage is a common complication in patients with nasopharyngeal carcinoma (NPC) treated with radiotherapy to head and neck region, which severely reduce the life quality of those patients. The aim of this study was to early evaluate the changes of irradiated parotid glands with T2 mapping and mDIXON Quant imaging. METHODS Forty-one patients with NPC underw...
