Proliferative activities in Spitz nevus compared with melanocytic nevus and malignant melanoma using expression of PCNA/cyclin and mitotic rate.


Proliferative activity in Spitz nevus (SN) was determined using proliferating cell nuclear antigen (PCNA) immunostaining and by assessing the mitotic rate. It was compared with that in compound melanocytic nevus (MN) and in malignant melanoma (MM). The PCNA index (number of positive cells/1,000 tumor cells) in SN was 72.8 +/- 45.5% (mean +/- SD), which was… (More)
