Although the number of reported cases is low, mucoepidermoid carcinoma is the most common malignant salivary gland neoplasm in the oral cavity. Its etiology is unknown. Clinically, it is described as a painful or painless swelling most often seen in the palate. Due to its great biological diversity, treatment and prognosis depend on the histological grade, location, and tumor stage. The objective of the present study was to describe a clinical case of mucoepidermoid carcinoma in a Brown female patient aged 45 years. Intraoral physical examination revealed a 1.0 cm diameter, bluish bubble with clear boundaries in the left retromolar region. The bubble had been there for roughly four months. An excisional biopsy was performed to confirm the clinical diagnosis of mucocele. Yellowish mucous leaked during the excision. The anatomical-pathological result was mucoepidermoid carcinoma, after which the patient was referred to a head and neck surgeon. Hence, we emphasize the importance of early diagnosis and proper management of this disease. Even when its clinical appearance is not suggestive of malignancy, mucoepidermoid carcinoma diagnosis should be considered in cases of proliferative oral lesions.
