Epithelioid hemangioendothelioma of the liver. Accidental detection of a solitary focus resembling a hepatic cyst

: The authors describe the case-history of a young woman with a solitary epithelioid haemangioendothelioma of the liver which on initial sonographic and CT examination reminded of a simple liver cyst. Aspiration biopsy under US control confirmed a solitary tumor evaluated under the influence of results of imaging methods, admitting the presence of a capsule, as a probable cholangiogenic adenoma developing into malignity. The patient was subjected to surgical extirpation of the tumor and the definite diagnosis of its vascular origin was assessed only during a detailed examination of the resected tissue. After an eight-month follow up the patient has no signs of relapse.
