Large Pleomorphic Adenoma of the Parotid Gland: Case Report

Abstract

Pleomorphic adenoma is a benign mixed tumor and the most common neoplasm of the salivary glands. This type of lesion typically presents as slow-growing and asymptomatic. The parotid gland is most frequently affected, accounting for approximately 85% of confirmed cases, although, with lower prevalence, it can also affect minor salivary glands. This report describes a case of pleomorphic adenoma in the superficial lobe of the parotid gland. The case involved a male patient, melanodermic, in his sixth decade of life, with an estimated development of the neoplasm over approximately ten years. Clinical examination revealed a painless swelling in the right parotid region, with a firm lesion upon palpation. Facial computed tomography showed a tumor mass located superficially in the right parotid gland. Surgical excision of the lesion was performed under general anesthesia, and the histopathological examination confirmed the preoperative diagnostic hypothesis of pleomorphic adenoma. After four years of follow-up, there was no recurrence, and the patient remains without esthetic-functional sequelae despite the large size of the lesion.
