Abstract
A 35-year-old housewife living in Seoul complained of a recurrent palpable abdominal mass. Excisional biopsy was done. The cystic mass showed an immature worm of Paragonimus sp. in the cyst cavity. It measured 7 × 4 mm and showed well-developed oral and ventral sucker, uterus, 5-branched ovary and intestine after acetocarmine staining. But the testes and vitelline duct were not developed fully and there was no egg in the uterus. The patient has eaten raw fish. The case of ectopic paragonimiasis in the abdominal subcutaneous tissue was presented.
