Apeculiar lesion of superficial soft tissue characterised by fibroma-like morphology and an immunohistochemical profile consisting of CK+, VIM+, CD34+, CD31+/-, FLI1+ and INI-1 retained is described. The lesion entered into differential diagnosis with the so-called fibroma-like variant of epithelioid sarcoma, with the entities defined as ES-like/pseudomyogenic haemangioendothelioma and the recently identified entity defined as superficial CD34+ fibroblastic tumour. All of these entities share a common morphological structure, but differ in their immunophenotypic profile.
