Skin localization of alveolar echinococcosis of the liver

Abstract

Alveolar echinococcosis is a rare parasitic disease caused by the intrahepatic growth of Echinococcus multilocularis larvae. Secondary localizations can be observed; pulmonary metastases are the most frequent and are observed in 22% of patients. Other extrahepatic localizations are less frequent. We describe two patients with abdominal skin involvement. To our knowledge, this has never before been reported. In both patients, the liver lesion was located in the left lobe, and larvae probably spread to the skin via the falciform ligament. In one patient albendazole therapy was effective.
