Intraduct papillomas of the salivary glands are rare solitary tumours. Most of the reported cases have occurred in minor salivary glands. A case which occurred in the parotid gland is reported. Fine needle aspiration was performed on this tumour, and the cytological appearances of the aspirate were suggestive of an adenoid cystic carcinoma. This is an important potential diagnostic pitfall which should be borne in mind when interpreting aspirates from salivary gland tumours.
