In our case, the initial diagnosis was thought to be fibroblastoma or other primary cardiac tumors, but after resection of the tumor and histopathological evaluation, the diagnosisofCATswas confirmed.

(114) Many histologic variants of DFPS have been described, including giant cell fibroblastoma (115) and those with fibrosarcomatous changes (DFSPFS), associated with a significantly more aggressive clinical course.
Interestingly, other neoplasms with fibroblastic/myofibroblastic differentiation evaluated by these authors (DFSP, LGFS, desmoplastic fibroblastoma, and fibromatosis) did not express this antigen.
Giant cell fibroblastoma (GCF) is a recently described, locally recurring childhood tumor of the superficial soft tissues.[1] It is currently classified with fibrohistiocytic tumors of uncertain biologic potential, although metastatic disease has never been reported.
