Development of neuroendocrine (Merkel cell) carcinoma mixed with squamous cell carcinoma in erythema ab igne.
Squamous cell carcinoma and neuroendocrine (Merkel cell) carcinoma are cutaneous neoplasms that have only occasionally been reported to coexist. Squamous cell carcinoma, but not neuroendocrine (Merkel cell) carcinoma, is a rare complication of erythema ab igne. This report describes the development of both neoplasms arising within the same tumor mass in an area of erythema ab igne.
