A Case of Merkel Cell Carcinoma in a Renal Transplant Patient / 대한이식학회지

ABSTRACT

Merkel cell carcinoma (MCC) is a rare, frequently lethal, primary neuroendocrine carcinoma of the skin. Histopathologically, it appears as a dermal nodule of small undifferentiated malignant cells. Historically, MCC was considered to be an eccrine carcinoma. Recognition of its neuroendocrine features later led to the hypothesis that it arose from Merkel cells in the skin, although recent evidences revisit the question of an epithelial origin. We recently experienced a Mercel cell carcinoma. So, we report a MCC case originated from skin in renal transplant patient who was administrated immunosuppressive agent.
