CT appearances of Marjolin's ulcer in the left gluteal region of a young man.

Chronic wounds and scar tissues are prone to skin cancer. In 1828, Jean-Nicholas Marjolin described the occurrence of tumours in post-traumatic scar tissue. He did not, however, identify the warty ulcers he described as malignant. It was Dupuytren, who about two years later, noted that these lesions were cancerous. The eponym was bestowed by Da Costa in 1903. Marjolin's ulcer no longer refers only to carcinomas secondary to burns and is classified as a malignancy that arises from previously traumatised, chronically inflamed, or scarred skin. It has been reported in relation to osteomyelitis, venous stasis ulcer, tropical ulcers, chronic decubitus ulcer, frostbite, pilonidal sinus, vaccination site, urinary fistula, hidradenitis suppurativa, skin graft donor site, gunshot wounds, puncture wounds, dog bites, and lupus rash. Early arising Marjolin's ulcer has rarely been described in literature. In this case report, we present the CT appearances of Marjolin's ulcer in the left gluteal region of a young man.
