Keloid Masking a Parotid Tumor

Abstract

A 37-year-old Nigerian woman presented with an itchy and occasionally painful scar that appeared after the healing of an acne lesion over the left parotid region, 13 years ago. She noticed a progressive increase; however, there was no history of facial weakness. Examination revealed a keloid lesion overlying a firm nontender mass. Ultrasound scan and fine-needle aspiration cytology indicated a benign tumor of the left parotid. Superficial parotidectomy was performed, and the histology revealed a keloid overlying a pleomorphic adenoma. This is an unusual presentation of keloid which developed over a pleomorphic adenoma. Hence, we report the above case for its rarity.
