Basal cell carcinomas (BCCs), the most common non-melanocytic neoplasm, display a considerable variety of appearances under light microscope as well as in clinical practice. BCCs can exhibit both a variety of histological growth patterns namely; superficial, nodular, micronodular or infiltrating and histological differentiation towards the cutaneous appendages, such as adenoid, keratotic, sebaceous, basosquamous/metatypical, pilar, apocrine, eccrine or fibroepithelial, adamantinoid, giant cell,

Adenoid basal cell carcinoma, a rare variant of basal cell carcinoma characterized by a specific histologic appearance, has been sparingly described and reports have been primarily limited to case series with limited data and only 12 cases have been reported in the English literature. An attempt is made to document the histological features of adenoid variant of BCC in a 65-year-old male, who presented with a slow growing ulceroproliferative lesion on nose. The case is being reported because of its rarity and to contribute in the spectrum of basal cell carcinomas.
