Basal cell carcinoma (BCC) arising from mucosal surfaces is extremely rare. Basal cell carcinoma arises from keratinocyte progenitor cells located in the upper infundibulum of hair follicles and sweat glands, mainly in the sun-damaged skin. Only a few cases of mucosal basal cell carcinoma (mBCCs) arising from the vermilion lip and oral mucosa have been reported, hence the origin of BCCs from skin appendages has been questioned. Owing to the rarity of mBCC, available literature regarding its clinical presentation, management and prognosis is scarce.
