ABSTRACT

Hemangioendothelioma is a rare vascular tumor whose etiology has not yet been defined. Currently, it is known to affect different sites, such as the abdominal-pelvic cavity. It is also known to present intermediate characteristics to hemangioma and angiosarcoma. In recent studies, 50-76% of patients are asymptomatic. Surgical treatment is indicated in most cases. The authors present a case of hemangioendothelioma with pelvic involvement and initial presentation as acute renal failure due to extrinsic ureteral compression, treated surgically, with histopathological diagnosis of hemangioendothelioma and recurrence after one year of the initial treatment presenting a histologically different form. This case illustrates a rare cause of lower urinary tract symptoms (LUTS), obstructive uropathy and acute renal failure and the appearance of two different tumors within a year, in line with the genetic/immunological factor in its genesis.

RESUMO

O hemangioendotelioma é um tumor vascular raro cuja etiologia ainda não foi definida. Atualmente, sabe-se que afeta diferentes locais, como a cavidade abdominal e pélvica. Sabe-se também que possui características intermediárias do hemangioma e do angiossarcoma. Em estudos recentes, 50-76% dos pacientes são assintomáticos. O tratamento cirúrgico é indicado na maioria dos casos. Os autores apresentam um caso de hemangioendotelioma com envolvimento pélvico e apresentação inicial como insuficiência renal aguda por compressão extrínseca ureteral, tratado cirurgicamente, diagnóstico histopatológico de hemangioendotelioma e recorrência após um ano do tratamento inicial, apresentando uma forma histologicamente diferente. Este caso ilustra uma causa rara de LUTS, uropatia obstrutiva e insuficiência renal aguda e o aparecimento de dois tumores diferentes dentro de um ano, em consonância com o fator genético/imunológico em sua gênese.
