Relapsing neoplastic seeding after percutaneous ethanol injection for hepatocellular carcinoma. Clinical and ultrasonographic findings in a cirrhotic patient.
A case of neoplastic implant after percutaneous ethanol injection (PEI) therapy for hepatocellular carcinoma (HCC) occurring in two steps is described. A 74-year-old male cirrhotic patient underwent PEI for a 5-cm HCC nodule. To obtain complete tumoral necrosis, 80 ml were injected under sonographic guidance in four sessions. Ten months after the completion of PEI a subcutaneous nodule was palpated in the abdominal wall within the area of needle punctures. Histologic examination of the excised nodule confirmed the sonographic and Power Doppler diagnosis of metastatic HCC. At the US exam scheduled three months later a non-palpable subcutaneous nodule of 16 mm was appreciated near the surgical wound. Once again metastatic HCC was demonstrated at pathological examination. Copyright 1997 Elsevier Science Ireland Ltd.
