Dermatofibrosarcoma protuberans: clinical, pathological, and genetic (<i>COL1A1‐PDGFB </i>) study with therapeutic implications

Abstract

The COL1A1-PDGFB fusion was present in all histological subtypes of DFSP, but not all cases expressed the fusion transcript. No association was observed between different COL1A1 breakpoints and clinicopathological parameters. Imatinib mesylate can be useful in locally advanced tumours and metastases.
