Abstract

Basal cell adenoma of the salivary gland is an infrequently encountered monomorphic adenoma, representing approximately 1–2% of all salivary gland tumors. It typically manifests as a firm, slowly enlarging mass in the parotid gland. Histologically, it is characterized by isomorphic cells arranged in nests and interlaced trabeculae, accompanied by a prominent basal membrane and a slack, hyaline stroma, devoid of myxoid or chondroid features. Due to its tendency to recur, differential diagnosis with pleomorphic adenoma, adenoid cystic carcinoma, basal cell adenocarcinoma and basaloid squamous cell carcinoma is crucial for prognostic evaluation and management. This report details a case of basal cell adenoma of the parotid gland, along with a review of the relevant literature, focusing on diagnosis and treatment strategies for this rare entity.
