Adenoid cystic carcinoma; cribriform or “Swiss cheese” pattern that is unmistakable but not always present. The cells show scanty cytoplasm and round to ovoid basophilic nuclei of regular form. The circular areas containing weakly eosinophilic amorphous basement membrane material accounting for the synonym “cylindroma.” Mucous and serous glands and the ducts of normal submandibular salivary gland are seen on the left. The gland was not invaded.
