Case #241 – December, 2008

A small, cream-colored worm-like object was discovered in the diaper of a 15-month-old child. The suspect worm was collected by the child’s parents and sent to the State Health Department for identification. A laboratorian at the State Laboratory identified the worm but requested confirmation. The specimen was sent to the Reference Laboratory at CDC for diagnostic assistance. Figures A and B show the gross morphology of the specimen. Figures C and D show smaller structures that were observed in the transport medium (10% formalin). These smaller structures were approximately 85 micrometers in length. What is your diagnosis? Based on what criteria?
