Mucous retention cyst (MRC) is a common submucosal lesion of the oral cavity that, when deeply seated, simulates a neoplasm. This report describes the fine-needle aspiration cytology findings of a lingual MRC of complex architecture and with metaplastic epithelium. In addition, we emphasize its cytologic differential diagnosis from other benign and malignant cystic lesions of the tongue. To the best of our knowledge, this is the first report of aspiration cytology of a complex MRC of the tongue.
