Basal Cell Adenoma of the Lip: A Report of Two Cases and Review of the Literature

Basal cell adenoma (BCA) is a tumor usually found in the parotid gland and less frequently in accessory glands. It is seen in the elderly, and it presents in the form of a solitary nodule, well-defined, and covered with healthy mucosa. Histological differential diagnosis should exclude basal cell adenocarcinoma (BCAC), which has histological similarities that may lead to an erroneous diagnosis. We present the cases of two patients diagnosed with BCA who consulted the Oral Surgery Department of the Consultation and Dental Treatment Center of the Ibn Sina University Hospital in Rabat.
