title: Persistent scrotal pain and suspected orchido-epididymitis of a young boy during pinworm (Enterobius vermicularis) infection in the bowel.
abstract: OBJECTIVE
  Pinworm (Enterobius vermicularis) is the most common parasite among mankind. Ectopic pinworm infections in number of organs are broadly reported. The aim of this report is to review the pinworm infection in the scrotum on the basis of our case.
  
  
  RESULTS
  Our patient is a young boy with persistent pain in the scrotums together with abdominal symptoms. He underwent several urgent operations. Pinworm was finally found in appendix vermiformis. We hypothesize that concurrent unresponsive orchido-epididymitis was caused by pinworm as well. Eradication happened finally with pyvrinembonate.
  
  
  CONCLUSIONS
  Pinworm is a parasite that lives usually in the bowel. Many ectopic locations, like scrotum, are known. Orchido-epididymitis by pinworm has to be kept in mind when treating boys with persistent scrotal pain.
