Iliopsoas hematoma in Gaucher's disease.

Gaucher's disease is an autosomal recessive inherited disease characterized by oraganomegaly, cytopenia and bone destruction. Clotting disorders and platelet dysfunctions are described. We report the case of a 22-year-old man who presented subacute groin pain due to spontaneous iliopsoas hematoma. Laboratory investigations found moderate thrombocytopenia, normal coagulation factor activities and unspecific platelet function test disturbances. His spleen was moderately enlarged and no significant bone lesions were found. Iliopsoas hematoma is a rare complication in Gaucher's disease and should be included in the differential diagnosis of pain localized to the groin-hip area, which could rather evoke hip osteonecrosis in this context.
