Dermatofibrosarcoma protuberans with areas resembling giant cell fibroblastoma: report of two cases

Abstract

Two cases of otherwise typical dermatofibrosarcoma protuberans showing a gradual transition to areas with the characteristic appearances of giant cell fibroblastoma are described. Both lesions were excised from the trunk of adults. These cases provide further evidence of the putative close relationship between these two neoplastic entities.
