Expression of the nm23 metastasis-suppressor gene product in skin tumors.

abstract：BACKGROUND:Among the pigmented lesions with a central area of scar, we found a group of cases histologically characterized by striking architectural alteration of the melanocytic component, but with no cytological atypia and mitotically quiescent. The aim of the current study was to assess the biological nature of such...
