Abstract
Two cases of monomorphic adenoma, dermal analogue type, are presented illustrating fine‐needle aspiration cytology and subsequent histopathology. Aspiration findings were similar in both cases, demonstrating aggregates of mildly disorganised small regular epithelial cells bordered by a thick rim of basement membrane material. In the first case seen, there was a prominent lymphoid component which gave rise to the false suspicion that the lesion was lymphoepithelial in nature. The cytological features of this tumour are characteristic, however, and their recognition is important to enable distinction from malignancy (e.g., adenoid cystic carcinoma), other benign neoplasms (e.g., pleomorphic adenoma), and non‐neoplastic conditions.
