AB  - Epithelioid hemangioendothelioma (EH) is a very rare 
vascular tumor of intermediate biological behavior. It 
can arise from various sites including bone, liver, spleen, 
pleura, lung, skin, or soft tissue. We report a case of a 
24-year-old man who presented with a history of acute 
urinary retention and a palpable lump in the lower 
abdomen. Imaging showed a large pelvic mass displaying 
heterogeneous texture with solid and cystic components 
compressing and displacing adjacent structures. The 
patient underwent exploratory laparotomy with excision 
of the pelvic mass. Histopathological examination 
confi rmed the diagnosis of EH. Pelvic soft tissue origin 
of EH is extremely rare. The diagnosis of EH may be 
suggested by characteristic magnetic resonance imaging 
(MRI) findings.
