## Abstract

Desmoplastic fibroma of bone is a very uncommon, benign but locally aggressive fibrogenic tumor. This report describes the case of a 45-year-old patient with a massive desmoplastic fibroma of the proximal tibia. A two-staged surgical procedure was successfully performed: wide resection and endoprosthetic reconstruction. Surgeons should be aware of the complexity of its treatment in the locally advanced and aggressive cases. A comprehensive review of the literature is also provided.

O fibroma desmoplásico do osso é um tumor fibrogênico muito incomum, benigno, mas localmente agressivo. Este relato descreve o caso de uma paciente de 45 anos com um enorme fibroma desmoplásico na tíbia proximal. Foi realizado com sucesso um procedimento cirúrgico em dois tempos: ressecção ampla e reconstrução endoprotética. Os cirurgiões devem estar cientes da complexidade de seu tratamento nos casos localmente avançados e agressivos. Uma revisão abrangente da literatura também é fornecida.
