Toker first described MCC more than 3 decades ago. Since then, it has been referred to as cutaneous neuroendocrine carcinoma, small cell tumor of the skin, primary undifferentiated carcinoma of the skin, anaplastic carcinoma of the skin, murky cell carcinoma, neuroendocrine tumor of the skin, or cutaneous APUDoma (a tumor composed of cells with amine precursor uptake and decarboxylation [APUD] cytochemical properties). The cell of origin is still a topic of debate, though most agree that MCC is of neuroendocrine origin. [4] Literature over the last several years has uncovered a strong association between MCC and a newly found polyomavirus (now named the Merkel cell polyomavirus, abbreviated MCV or MCPyV).
