DESMOPLASTIC FIBROBLASTOMA ENTRAPPING BRACHIAL ARTERY — A UNIQUE CASE REPORT
Desmoplastic fibroblastoma (DF), also known as collagenous fibroma, is a rare benign fibrous tumor, recently described. It occurs predominantly in trunk and upper limbs, and can appear at any age. The authors describe a case of a 42-yearold female patient with DF, with upper limb neurovascular compromise. Patient was submitted to block excision of the tumor mass and brachial artery, with arterial reconstruction (autologous interposition graft). The anatomopathological analysis was consistent with DF and the diagnosis was validated by an international external laboratory1. This is the first description in the literature of an DF involving an arterial segment.
