Abstract
Aim Mucoepidermoid carcinoma (MEC) is the most commonly diagnosed malignant tumor of the salivary glands. While it predominantly occurs in the parotid gland, it may also affect the submandibular, submental, and minor salivary glands. This case report aims to contribute to the literature by presenting a low-grade MEC, clinically resembling benign lesions, detected asymptomatically in the hard palate. Case Report A 30-year-old female patient with no systemic health issues visited the Department of Dentomaxillofacial Radiology at Sivas Cumhuriyet University Faculty of Dentistry for a routine examination. An asymptomatic, well-defined swelling with a slightly erythematous mucosal covering was detected at the junction of the hard and soft palate. The patient was not aware of the lesion. Histopathological analysis of the tissue sample, obtained through an incisional biopsy, confirmed features indicative of low-grade MEC. Discussion Low-grade MEC can mimic benign salivary gland tumors, particularly pleomorphic adenoma, when presenting as an asymptomatic palatal lesion. This highlights the necessity of biopsy for accurate diagnosis. Early detection enables conservative treatment and improves prognosis. While surgical excision with clear margins is the preferred approach, long-term follow-up is essential due to the risk of recurrence. Conclusion Asymptomatic low-grade mucoepidermoid carcinoma can be confused with pleomorphic adenoma when it occurs in the palatal region and must be considered in the differential diagnosis. Early-stage diagnosis of MEC is associated with a better prognosis and allows for more conservative treatment approaches.
