title: Subcutaneous sparganosis--a case report and a review of human sparganosis in Taiwan.
abstract: Human sparganosis is a rare parasitic disease infected by plerocercoid larva (sparganum) of Spirometra species. It was usually diagnosed accidentally and has long been underestimated. In this report, we describe a 53-year-old woman presenting as an enlarging subcutaneous nodule in the right thigh for 3 months, which was excised in the belief that it was a lipoma. Characteristic sparganum accompanied by granulomatous inflammation, eosinophilic infiltrate and sinus tract in the subcutaneous tissue were discovered under microscopic examination of the excised tissue. Contaminated drinking water was presumed to be the infectious source. Complete excision is a curative treatment. We also review previously documented 19 human sparganosis in Taiwan to provide the clinical context for this report.
