Pigmented Basal Cell Carcinoma in Marjolin's Ulcer

Marjolin's ulcer is a carcinoma that develops in chronic benign ulcers or scars. It was first found to be associated with chronic osteomyelitis. Squamous cell carcinoma is the most common cancer which is being noted in Marjolin's ulcer. Suspicion of such lesions should be raised in chronic wounds which demonstrate characteristic changes. Diagnosis is made by doing a biopsy and it is treated by wide local excision. We are reporting here a case of 65-year-old female who presented with a growth in a long standing scar over her back. Scar was caused by an incision and drainage for an abscess performed 30 years back. On biopsy, features of pigmented variety of Basal Cell Carcinoma (BCC) were seen. Though occurrence of basal cell carcinoma in Marjolin's ulcer is known, pigmented variety is yet to be reported. The rare varieties like pigmented type of basal cell carcinoma in Marjolin's ulcer, must be borne in mind by histopathologists.
