“…Cutaneous SCC occasionally occurs on lesions of burn scars, chronic leg ulcers, chronic osteomyelitic sinuses, and chronic perianal pyoderma (7)(8)(9)(10)(11). An association of cutaneous SCC with sporadic PCT has not been reported so far to our knowledge, but we do not think that the association happened by chance.…”

A 56-year-old man suffered from cutaneous squamous cell carcinoma (cutaneous SCC) which occurred on a cutaneous lesion of sporadic porphyria cutanea tarda (sporadic PCT). His liver function decreased from the time he was infected with Schistosoma japonicum at the age of 10. He drank a little alcohol. Erythematous maculae with blisters or erosions occurred on sun-exposed areas of his skin when he was 52. His urine continued to be red. After detailed examinations including liver biopsy, he was diagnosed as having sporadic PCT due to liver disorder after infection with Schistosoma japonicum. At the age of 56, a small red papule arose on his right earlobe at the site of a sporadic PCT lesion. The papule rapidly enlarged with ulceration; this completely destroyed his right earlobe, which was covered with odoriferous yellow-white necrotic tissue. The tumor then extended to his right preauricular area with ulceration. A skin biopsy confirmed well-differentiated cutaneous SCC. The association of cutaneous SCC with sporadic PCT has not been previously reported; we think that the association is significant. Such an occurrence may have been induced by either direct or indirect effects of ultraviolet light or a scar formed by the sporadic PCT.

“…Squamous cell carcinomas rarely arise from perianal fistulae. In the literature only 10 similar cases have been reported (1–8). Here, we are reporting a case of squamous cell carcinoma that arose from long‐standing perianal fistula and how we managed it surgically.…”

Perianal fistula is a very common problem in general population. Ninety percent of perianal fistulae arise from infected anal glands, and they often give rise to perianal abscesses. Very rarely perianal fistulae and abscesses undergo malignant transformation and give rise to carcinomas, mainly adenocarcinomas. We are reporting a case of squamous cell carcinoma arising from long-standing perianal fistula and how we managed it surgically.
