ABSTRACT
Introdução. O sarcoma radioinduzido é entidade rara que pode ocorrer em qualquer tecido irradiado. O subtipo histológico mais comum é o fibro-histiocitoma maligno, cujo comportamento é agressivo com prognóstico sombrio. Em geral, a ressecção ampla tridimensional com margens livres tem sido o melhor tratamento curativo. Caso. Os autores relatam um caso deste raro tipo de sarcoma localmente avançado, na região púbica, tratadopor hemipelvectomia interna alargada, com boa evolução. A ressecção teve margens livres. Não houve recidiva até o momento, com seguimento de um ano. Conclusão. A despeito de seu comportamento agressivo, o fibro-histiocitoma radioinduzido da região púbica com invasão óssea pode ser adequadamente controlado com ressecção ampla e hemipelvectomia alargada.
Introduction. Postradiation sarcoma is a rare entity that may occur on every irradiated tissue. The most common histological subtype is malignant fibrohistiocytoma. It presents both aggressive behavior and dismal prognosis. Generally, wide resection with free margins has been considered the best curative treatment. Case. The authors present a single case of this rare type of locally advanced sarcoma on the pubis region that was treated by means of enlarged internal hemipelvectomy with a good outcome. Resection was R0 (free-margins). There was no recurrence after one year of follow-up period. Conclusion. Despite its aggressive behavior, postradiation fibrohistiocytoma on the pubic region with bone invasion may be controlled by means of enlarged internal hemipelvectomy.
