Abstract

A 32-year-old woman was admitted to our department for hematuria and dysuria.

Computed tomography (CT) and cystoscopy revealed a 2-cm pedunculated tumor with rich blood supply and a smooth surface in the bladder trigone. We performed a transurethral resection of bladder tumor. The pathologic diagnosis was alveolar soft part sarcoma (ASPS). CT, bone scintigraphy, positron emission tomography, and pelvic magnetic resonance imaging revealed no other lesions; thus, she was diagnosed as having a primary bladder ASPS. Postoperative follow-up with regular cystoscopies and CTs over 10 years have shown no local recurrence or metastasis.

Primary ASPS of the bladder is exceedingly rare, and this case is the 8th case (the 2nd case in Japan) reported in literature.
