A Case of Sparganosis that Mimicked Recurrence of Contralateral Breast Cancer / 대한내과학회지

Sparganosis is a rare parasitic infection caused by plerocercoid tapeworm larvae of the genus Spirometra. While initially asymptomatic, the migrating larvae initially appear as subcutaneous nodules, which can be mistaken for cancer because all parts of the body can be affected, including the abdominal cavity, genitourinary tract, gastrointestinal tract, musculoskeletal system, central nervous system, and even the breasts. Therefore, we report here a case of sparganosis that was differentially diagnosed from recurrence of breast cancer.
