Immunohistochemical profiles of different subsets of Merkel cell carcinoma

The objectives of the current study were (1) to examine the immunohistochemical profile of different subsets of MCC to determine whether predictable subset-specific patterns exist and (2) to establish whether shared immunophenotypic patterns might reveal links between individual subsets, as demonstrated previously at a genetic level. In 52 cases of MCC, stratified by viral status and morphology, we studied 5 markers commonly used in the diagnostic evaluation of these tumors (CK20, CK7, chromogranin, neurofilament and TTF-1).
