Mucoepidermoid Carcinoma in a Young Patient: A Case Report

Abstract

Mucoepidermoid carcinoma is the most common malignant tumor of the major and minor salivary glands, especially in the fourth decade of life. Genetic disorders, exposure to ionizing radiation, and smoking are reported as major risk factors. A 15-year-old female was referred to a head and neck outpatient clinic, presenting with a swelling of the parotid gland in the right preauricular region, causing lifting of the earlobe. A biopsy was performed with the hypothesis of pleomorphic adenoma. On gross examination, it was observed a tumor-like mass partially covered by a capsule, measuring approximately 5 cm. Microscopic examination revealed malignant neoplasm of the salivary gland, composed predominantly of cystic spaces lined with mucous cells and sometimes showing papillary proliferations. Solid arrangements of squamous cells groups were also seen in few areas of the lesion. The final diagnosis was low-grade mucoepidermoid carcinoma. The patient was referred to an oncology center.
