Pseudosarcomatous fibromyxoid tumor of the bladder.

Pseudosarcomatous fibromyxoid tumors are uncommon lesions with uncertain pathogenesis. We present the case of a 36-year-old healthy patient who was evaluated for painless gross hematuria. Work-up revealed a bladder mass that was initially treated with transurethral resection that showed pseudosarcomatous fibromyxoid tumors. However, the mass recurred and was subsequently treated definitively with partial cystectomy with no recurrence at last follow-up. Partial cystectomy is a viable option in the treatment of recurrent symptomatic pseudosarcomatous fibromyxoid tumors of the bladder, when performed selectively.
