title: Immunocytochemical study of a trabecular carcinoma of the skin (Merkel cell tumor). Case report.
abstract: The existence of different neuroendocrine markers was investigated by immunocytochemistry in a case of Merkel cells tumor. Neuroplastic cells contain NSE,NF,CK and chromogranin A i.r. On the basis of the results the neuroendocrine nature of this uncommon neoplasm of the skin is confirmed and it is suggested that chromogranin A could represent an additional marker for Merkel cells tumors.
