RESUMO
O histiocitoma fibroso é tumor heterogéneo composto por fibroblastos, histiócitos e vasos sanguíneos. Efectuamos uma revisão histopatológica retrospectiva de 95 biopsias de histiocitomas fibrosos do nosso arquivo dos últimos 3,5 anos, com o objectivo de avaliar a localização, delimitação, alteração da epiderme, indução folículo-sebácea, celularidade, vascularização, padrão do colagénio e tipo de células constituintes. Na maioria das biopsias, confirmamos as características histopatológicas clássicas dos histiocitomas fibrosos. Achados interessantes observados no nosso estudo foram presença de células nódulos linfoides, mastócitos e infiltrado de células inflamatórias.
ABSTRACT
Fibrous histiocytoma (FH) is a heterogeneous tumor composed of fibroblasts, histiocytes, and blood vessels. We conducted a retrospective histopathologic analysis of 95 biopsies, performed over the last 3.5 years, of fibrous histiocytomas to analyze the location, delimitation, epithelial changes, induction of folliculo-sebaceous structures, cellularity, vascularity, collagen pattern, and types of composite cells of the FH. In the majority of the biopsies, we confirmed the classical histopathologic features of fibrous histiocytomas. The presence of lymphoid nodules, mast cells, and sparse infiltrate of inflammatory cells was an interesting finding observed in our study.
