Supraumbilical skin rash and fat necrosis after transcatheter arterial chemoembolization: a case report

We report the case of a 63-year-old female who had chronic hepatitis C and who was diagnosed with hepatocellular carcinoma. Hepatic angiography showed one visible and tortuous falciform artery arising as the terminal branch of the left hepatic artery. Transcatheter arterial chemoembolization (TACE) was performed via the left hepatic artery. The patient developed supraumbilical skin rash with local tenderness on the following day. After supportive treatment by a dermatologist, the skin rash subsided gradually with sequelae of irregular skin surface and one small subcutaneous nodule. Skin biopsy of the lesion 1 year later showed fat necrosis with foreign body reaction and fibrosis. We discuss this rare complication of TACE and review the literature.
