## TL;DR

This paper reports two cases of a rare lip tumor called basal cell adenoma and discusses its diagnosis and characteristics.

## Contribution

The paper adds to the limited literature by presenting two new clinical cases of BCA in the lip.

## Key findings

- BCA typically appears as a solitary, well-defined nodule covered with healthy mucosa.
- Distinguishing BCA from basal cell adenocarcinoma is crucial to avoid misdiagnosis.
- The cases were diagnosed and managed at a university hospital's oral surgery department.

## Abstract

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.
