Abstract

Human sparganosis is a food-borne zoonosis mainly caused by the plerocercoid belonging to the genus Spirometra. The most common clinical sign of sparganosis is a subcutaneous mass in the trunk including abdominal or chest wall. The mass may be mistaken for a malignant tumor, thereby causing difficulty in terms of diagnosis and treatment. A 66-year-old woman visited our clinic for the removal of a lipoma-like mass. It was movable, hard, and painless. we identified 2 white mass, measuring $0.2{\times}4cm$ and $0.2{\times}1cm$. Pathologic finding indicated the white mass was a sparganum. She recalled having eaten a raw frog approximately 60 years before. A 35-year-old who lived North Korea was also presented to our clinic with an asymptomatic nodule on her abdomen. Intraoperatively, we found sparganum approximately 24 cm size. Subcutaneous masses are associated with clinical signs of inflammation or they may mimic a soft tissue neoplasm. While the incidence rate of sparganosis has decreased with economic development and advancements in sanitation, surgeons still encounter patients with sparganosis in the clinical setting. Therefore, a careful history is required in order to diagnose sparganosis.
