A Case of Fatal Growth at Liver Lesions in Epitheloid Hemangioendothelioma Involving Lung and Liver

Background. Epitheloid hemangioendothelioma is a rare tumor which originates from hemangioendothelial cells. We report a case of epitheloid hemangioendothelioma involving the lung and liver. Case. A 29-year-old man was admitted to our hospital, because of multiple small nodular shadows on a chest radiograph and CT taken at a regular medical examination. Open lung biopsy yielded a diagnosis of epitheloid hemangioendothelioma of the lung. His abdominal CT showed some small nodular shadows in the liver, which were diagnosed as the same epitheloid hemangioendothelioma by laparoscopic biopsy. He was followed with no treatment for the tumors, and six years later, he was admitted to our hospital because of epigastralgia. The lung lesions were slightly enlarged compared to six years previously, but the liver lesions had significantly enlarged and the left branch of the portal vein was occluded by compression or invasion of the tumor. Transcatheter arterial embolization was done, but showed no effect. Then, he suffered from jaundice due to the enlarged liver tumors. Six years and eight months after the first admission, he died. Conclusion. This rare case of epitheloid hemangioendothelioma involving the lung and liver was unique in terms of the enlargementof the liver lesions.
