Basal cell carcinoma (BCC) is the most common skin neoplasm, 85%-90% of which is localized in the head and neck region. BCCs of covered sites have been considered unusual because of their location. In this case series we present 4 cases in which BCC appeared in covered, non-sun exposed areas of the skin. Amongst the 4 cases, case 1 is classified under difficult-to-treat BCC, case 2 and 4 are that of pigmented variant, one of which, case 2, was clinically suspected to be a melanoma and case 3 is a giant BCC with an increased risk of recurrence. This case series stresses on the fact that a clinician should be aware of the possible diagnosis of BCC and include it as a differential despite its occurrence in unusual locations and such cases need to be reported so that their pathogenesis, diagnostic criteria, intervention methods and post care can be understood.
