A rare occurrence of basal cell adenoma of palate: A case report with comprehensive immunohistochemical analysis.

Basal cell adenoma (BCA) of the salivary glands is an uncommon type of monomorphic adenoma which constitutes 1% of all salivary gland tumors. It most commonly involves parotid gland, while it rarely occurs in minor salivary glands. Upper lip, buccal mucosa, and lower lip are the common intraoral sites; whereas, palate being the rarest one. Due to prognostic implications, differential diagnosis with basal cell adenocarcinoma, basaloid squamous cell carcinoma, and adenoid cystic carcinoma (AdCC) is mandatory. Considering the rarity of this lesion and histologic paradox regarding its diagnosis, we report a case of BCA of palate with emphasis on need of comprehensive immunohistochemical (IHC) analysis.
