A case of deep lobe parotid lipoma

Lipoma of the Parotid Gland: A Case Report

“…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.…”

“…Fine needle aspiration cytology (FNAC) has great value in the diagnosis of parotid tumors and requires an experienced cytologist. Its accuracy drops to less than 50% in the cases of parotid lipomas [5][6][7][8][9][10][11][12][13]. On imaging, CT scan shows hypodense, homogeneous and well delineated mass with few septations and negative attenuation, without contrast enhancement [3][4][5][6][7][8][9][10][11][12][13].…”

“…Its accuracy drops to less than 50% in the cases of parotid lipomas [5][6][7][8][9][10][11][12][13]. On imaging, CT scan shows hypodense, homogeneous and well delineated mass with few septations and negative attenuation, without contrast enhancement [3][4][5][6][7][8][9][10][11][12][13]. However, CT scan cannot distinguish lipoma from surrounding adipose tissue.…”

“…Identification of a capsule may aid in distinguishing such a neoplasm from pseudolipoma, lobular lipomatous atrophy, or lipomatosis, all of which are unencapsulated [3]. Surgery is the treatment of choice of parotid gland lipoma, but its modalities remain controversial [8][9][10][11][12]. It should be performed by experienced surgeons because of the need for meticulous dissection of the facial nerve branches.…”
