Cytogenetic and immunohistochemical evidence that giant cell fibroblastoma is related to dermatofibrosarcoma protuberans

From cytogenetic and immunohistochemical findings in a primary giant cell fibrosarcoma and its recurrence, it is further demonstrated that a close relationship exists between this tumor and dermatofibrosarcoma protuberans. Both tumors express CD34 and show rearrangements of chromosomes 17 and 22. Genes Chromosom Cancer 15:73–75 (1996). © 1996 Wiley‐Liss, Inc.
