Minor Salivary Gland Origin Tubular Basal Cell Adenoma of the Upper Lip

BCA is a rare benign tumour that arises from the epithelial cells of the salivary glands. Due to its distinct histological features, it was once categorized as a monomorphic adenoma subtype. typically affecting older female patients' primary salivary glands. BCA manifests as slowly growing, asymptomatic masses that are biased toward age and location. Histologically, solid, trabecular, tubular, and membrane-like patterns can be distinguished. Before beginning treatment, it is essential to distinguish between BCA, pleomorphic adenoma, and malignant salivary gland tumors in order to provide effective care. The standard of care is to surgically remove the tumour. Except for the membrane subtype, malignant transformation and recurrence are rare. This research aims to report an unusual case of BCA that originated from a small salivary gland located in the upper lip. Since most cases of basal cell adenomas occur in the parotid glands, they make about 1% of all salivary gland cancers.
