Steinbichler , Undine Hauser , Volker H. Schartinger , József Dudás , Herbert Riechelmann Recommend Article Abstract Buy Article All articles of this category Merkel-Zell-Karzinome (MCC) sind hochmaligne neuroendokrine Tumore der Haut. Auch wenn sie sehr selten sind, hat sich ihre Inzidenz in den letzten 20 Jahren verdoppelt. Ihre Mortalität ist höher als die des malignen Melanoms. Risikofaktor ist neben UV-Exposition eine iatrogene oder anderweitige Immunsuppression. MCC betreffen vor allem Menschen jenseits des 70. Lebensjahrs und treten in der Hälfte der Fälle in der Kopf-Hals-Region auf. Full Text References Literatur 1 Erovic I, Erovic BM. Merkel cell carcinoma: the past, the present, and the future.
