Abstract                                                                            

Fibroadenoma is a non-cancerous tumor commonly associated with the female breast and has been known to be hormone dependent. Fibroadenomas are known to present as solitary mobile masses within the young female breast and are mostly benign. Bladder outlet obstruction from fibroadenoma in a male patient is of extreme rarity and none of the reported cases of fibroadenoma in the male urinary bladder has been associated with this presentation. We herein present this rare finding within the male bladder, and a literature review of fibroadenomatous disease in men.

Cystoscopy and transurethral excision was performed for a suspected case of obstructive bladder tumor after ultrasonography showed a mass within the bladder neck region, in a patient presenting with acute urinary retention. Biopsy samples of the mass and surrounding tissue were taken and sent for histopathological examination. Pathological diagnosis of fibroadenoma of the urinary bladder was made after careful histopathological examinations. A meticulous search was made for supportive literature, which revealed two reported cases of fibroadenoma within the male urinary bladder but no association between fibroadenoma in this location and acute urinary retention or bladder outlet obstruction has ever been reported.

This report aims to further establish fibroadenoma as a definitive disease entity, possible etiology for obstructive bladder tumors and encourage further study into other possible clinical presentations and sequelae.
