Lipomas are common benign soft tissue neoplasms, however they are found seldom within the deep lobe of the parotid gland. Surgical intervention in parotid mass is difficult owing to the proximity of the facial nerve and so information of anatomy and surgical procedures are essential. A sixty-four-year-old female presented with a left cheek mass from one-year period that was painless and didn’t grow in size with chewing. A high-frequency sonography visualized a hypoechoic mass measuring 3.2× 2.6 × 2 cm in left parotid region with well-defined margins and heterogeneity for the presence of fibrous septae. Magnetic resonance imaging confirmed, on T1- and T2-weighted images, a well-described hyper intense lesion within the left parotid gland that was hypo intense on STIR images. A first-class needle aspiration cytology (FNAC) became conclusive for the presence of “homogeneous proliferation of mature adipocytes,” compatible with lipoma. She then underwent left superficial parotidectomy. Histopathology confirmed it as a parotid lipoma. The patient had an uneventful recovery, with a normal facial contour and intact seventh cranial nerve function. Lipoma of the parotid gland is extremely rare and may be clinically deceptive. CT and MRI, have a vital position because they locate the neoplasm on the parotid gland and facilitate the diagnosing of lipoma. Benign or malignant differentiation within the mass of parotid glands is of high importance.
