Basal cell adenoma-parotid: a rare entity

Abstract

Basal cell adenoma is a rare benign tumour found in the parotid gland, typically in patients aged between their fifth and seventh decades. In two cases we observed, patients presented with a gradually increasing, painless, and movable swelling in the parotid region. The condition was successfully managed through a Superficial Parotidectomy operation, and the final histopathological report confirmed the presence of basal cell adenoma. This tumour is one of the 11 benign salivary gland tumours classified by the WHO and represents only 3% of head and neck neoplasms. It is primarily located in the superficial parotid gland, and due to its rarity, there is limited literature available on this entity. Diagnosing such tumours is crucial, as non-invasive diagnostic procedures are not always reliable in distinguishing between benign and malignant conditions. A differential diagnosis with basal cell adenoid cystic carcinoma and basaloid squamous cell carcinoma is necessary due to their differing prognostic implications. Early and accurate identification is essential to guide appropriate treatment and improve patient outcomes.
