Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about three people per million members of the population.[1] It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin.[2] Factors involved in the development of MCC include the Merkel cell polyomavirus (MCPyV or MCV), a weakened immune system, and exposure to ultraviolet radiation.[3] Merkel cell carcinoma usually arises on the head, neck, and extremities, as well as in the perianal region and on the eyelid.[4] It is more common in people over sixty years old, Caucasian people, and males.[5] MCC is less common in children.[1][4]
