The most commonly occurring malignant salivary gland tumor is mucoepidermoid carcinoma (MEC). It consists of intermediate cells, squamous cells, and mucous-secreting cells. It is usually not capsulated and is identified by mucocarmine staining. Mucoepidermoid carcinoma exists in the thyroid gland and lungs as well. This report presents a case of a very rare sclerosing variant of MEC of the parotid gland in a 48-year-old patient. The patient presented with a small swelling below the left earlobe. Ultrasound-guided fine-needle aspiration cytology (FNAC) was carried out. A diagnosis of pleomorphic adenoma was given. The patient underwent a partial parotidectomy under general anesthesia. The final diagnosis was made through histopathological examination after the surgical removal of the tumor. The patient is now under close follow-up to look out for a recurrence. This case highlights the importance of recognizing and managing rare variants of MEC to optimize patient outcomes.
