title: Proliferating larval cestodiasis: report of a case.
abstract: A 72-year-old Filipino man who had emigrated to Canada had an abdominal infection with a proliferating acephalic larval cestode. Small, irregularly shaped parasites were within the substance of a lymph node, where they provoked a fibrogranulomatous and eosinophilic reaction. The parasite is described and is identified as an undifferentiated sparganum or tetrahyridium based upon comparison with two similar parasites from patients in Taiwan and Paraguay.
