A CASE OF AGGRESSIVE ANGIOMYXOMA GROWING INTO THE PELVIC CAVITY

Abstract

We report a case of aggressive angiomyxoma growing into the pelvic cavity massively. A 36-year-old woman was admitted to the hospital because of abdominal massive tumor. Pelvic CT scan, magnetic resonance imaging and angiography revealed that the tumor occupied the entire pelvic cavity, and resultantly the uterus, bladder and rectum were remarkably oppressed. For suspected myxoid liposarcoma, we performed an operation. Resected specemen was 34×21 cm in diameter with smooth surface and gelatinous appearance. Postoperative pathological examination revealed aggressive angiomyxoma.
Aggressive angiomyxoma is uncommon. In Japan, about 30 cases have been reported in the last 15 years. Most patients presented with a genital or perineal mass. The case wihout symptoms at these regions and growing into the pelvic cavity is rare. We report the case with some bibliographical comments.
