Lipoma of the Parotid Gland

Lipoma of the Parotid Gland: A Case Report

“…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. 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.…”
