ABSTRACT = {Angiosarcomas are soft tissue malignancies of connective 
tissue origin with rapid hematogenous spread, but are 
extremely uncommon primary tumors of the bladder 
with approximately ten reported cases in the 20th century. 
We report a 59-year-old man with benign prostatic 
hyperplasia (BPH) and gross hematuria who underwent 
a bladder biopsy for a markedly thickened bladder wall on 
CT scan. Biopsy specimens demonstrated deep vascular 
malformations that were concerning for a malignancy. 
Intense pathological review was initially not defi nitive 
and transurethral resection of the prostate (TURP) was 
performed for his symptoms. Interestingly, surgery 
reversed the bladder process. This case serves as a unique 
example of how the sequelae of bladder outlet obstruction 
(BOO) can resemble a malignant process on presentation 
but represent no more than hypertrophic adaptations in 
the bladder wall musculature of a patient with BPH and 
signifi cant outlet obstruction.},
