The authors describe a rare case of hepatocellular carcinoma that metastasized to the pectineal muscle of the right thigh. The patient had been treated with surgical procedures and with multiple sessions of transarterial chemoembolization, one of which was complicated by a right femoral artery hematoma at the catheter insertion site. It is unclear whether the muscle metastasis was caused by blood-borne spread or by tumor-cell seeding caused by the TACE procedure.
SommarioGli autori descrivono un raro caso di localizzazione mestastatica da epatocarcinoma in sede muscolare (muscolo pettineo della coscia dx); il paziente era stato sottoposto a procedure chirurgiche ed a Tace.Per tale motivo non è dimostrabile se l'insemenzamento sia legato ad una diffusione ematogena con interessamento del muscolo pettineo o sia legato ad un seeding iatrogeno secondario alla manovra terapeutica.
