Huge Lipoma of the Right Parotid Gland: Case Report and Review of 42 Cases

Abstract

Lipomas are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. The parotid lipoma is a slowly growing, asymptomatic, freely movable, soft mass. Preoperative diagnosis is generally difficult. We present a case of a slowly enlarging mass of the parotid region in a 44-year-old man that proved to be a lipomatous tumor of the parotid gland. We also review 42 other cases from the literature. Our patient's huge tumor was located in the superficial lobe of the gland, and a parotidectomy with preservation of the facial nerve was performed. There was no complication or recurrence of the tumor after a follow-up of 1 year.

Osteolipoma of Parotid Gland: A Rare Presentation

“…However, it remains under controversy for the management of parotid gland osteolipoma, as well as lipoma. Several methods have been proposed for managing the parotid lipoma, including enucleation or excision with a small border of parotid gland for encapsulated intra or paraparotid lipomas, super cial parotidectomy and total parotidectomy 10,22,23 . Unsurprisingly, super cial parotidectomy is preferred by most authors.…”

Lipoma of the Parotid Gland: A Case Report

“…Lipoma is one of the most frequently encountered benign mesenchymal tumors that may originate from adipose tissue in any part of the body [3,4]. Rarely, it can develop in the parotid gland with reported incidence ranging from 0,6% to 4,4% among parotid tumors [3,5].…”

“…Clinical diagnosis may be difficult [9], especially for tumors located at the deep parotid lobe because it is difficult to evaluate the relationship between these masses and the surrounding tissues. Those situated at superficial parotid lobe usually appear as a slow growing, non-tender, movable and well-differentiated soft mass in parotid region [3][4][5][6][7][8][9][10]. Facial paralysis and pain are uncommon signs and rarely have been described [5][6][7][8][9][10][11].…”

“…Facial paralysis and pain are uncommon signs and rarely have been described [5][6][7][8][9][10][11]. This benign clinical presentation is most often mistaken for Warthin tumor or pleomorphic adenoma [3][4][5][6][7][8][9][10][11][12]. Fine needle aspiration cytology (FNAC) has great value in the diagnosis of parotid tumors and requires an experienced cytologist.…”

“…The operation can be planned avoiding the injury to facial nerve and its branches. 5 We report a case of sialolipoma in the left parotid of a 52year old female woman because of relative rarity who was treated with limited excision.…”
