A 26-year-old man presented with a large, painless, mobile, pedunculated, fluctuant, and nontransilluminant swelling hanging in front of the left ear. He had undergone superficial parotidectomy 9 months ago elsewhere for chronic nonspecific sialadenitis of left parotid gland. The fine needle aspiration was nondiagnostic and revealed turbid dark yellow color fluid. A total parotidectomy was performed to remove the lesion completely as the tumor was involving the deep lobe. Histopathology was consistent with features of low-grade mucoepidermoid carcinoma. Immediate postoperatively the patient had a House and Brackman grade III left facial nerve paresis, which later improved to grade II. This unusual presentation of malignant transformation of chronic nonspecific sialadenitis is one of the rare unique reported cases to our knowledge.
