Of the salivary gland tumors, mucoepidermoid carcinoma is probably the most difficult to diagnose accurately by aspiration cytology. It is the second most common tumor in the pediatric age group in parotid gland after pleomorphic adenoma and differentiating between both can be diagnostically challenging. We are hereby presenting a case of 13 year old female child with right parotid lesion. The combination of overlapping intermediate and mucus producing cells with abundant background and intracytoplasmic mucin helped us in making the diagnosis of intermediate mucoepidermoid carcinoma. Subsequently total parotidectomy revealed a low grade mucoepidermoid carcinoma. Hence we concluded that abundant mucin with good cellularity can be seen in low grade mucoepidermoid carcinoma. Grading of mucoepidermoid carcinoma is also important to determine the prognosis.
