DFSP is characterized by infiltrative growth and a high propensity for local recurrence after surgical excision [14]. Despite its locally aggressive behavior, DFSP has little metastatic potential [1-4], and when distant metastasis does occur, it alm...
This report describes a case of congenital dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous (FS) and myxoid areas. Immunohistochemical results showed that tumour cells in ordinary DFSP areas were diffusely positive for CD34, whereas in the FS and myxoid areas, few tumour cells were positive for this antigen. Ki-67 positive tumour cell numbers were greater in the FS (11.8%) and myxoi...

We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory.
