title: [Ultrastructural study of 14 cases of dermatofibrosarcoma protuberans].
abstract: 14 cases of dermatofibrosarcoma protuberans (DFSP) were investigated with electron microscopy. Perineural cells, fibroblasts and primitive mesenchymal cells were found in all cases with perineural cells as the most prominent component. The findings suggest that DFSP is a tumor with heterogeneity, most probably arising from primitive dermal mesenchymal cells which have the potential for differentiation toward different cell lines, especially toward perineural cells.
