Abstract
At the histological examination of an increasing number of melanocytic tumors there is a need to use various immunohistochemical methods. Currently, we are supplied by several antibodies working well on formalin-fixed, paraffin-embedded samples. We have tested five antibodies (S-100, HMB-45, Melan-A, MITF, PNL-2) on 34 benign and 34 malignant melanocytic tumors. We examined the specificity and sensitivity in the junctional and dermal component separately, with special consideration to features disturbing the evaluation (regression, halo-like inflammation, etc.). We have concluded that the histological diagnosis of melanocytic tumors is based on the detailed examination of traditional HE slides and the immunohistochemical methods only confirm or weaken our opinion.
