Hepatic epithelioid hemangioendothelioma in a young female.

Epithelioid hemangioendothelioma in a young female is reported. Her symptoms were right upper quadrant pain and low-grade fever. Laboratory examinations showed an increased number of white blood cells and an elevated erythrocyte sedimentation rate. Plasma factor VIII:C was increased. The hepatic lesions were demonstrated as low-density areas by CT scan, and multiple nodules with central depression on the surface of the liver were identified by peritoneoscopy. The biopsy specimens showed spindle-shaped tumor cells set in the fibrous and myxohyalinous tissue. The tumor cells were positive for factor VIII-related antigen and Weibel-Palade bodies. The patient received transcatheter arterial embolization therapy using Gelfoam and mitomycin C following which the plasma level of factor VIII was normalized and regression of the tumors was observed.
