Right testicular pain and epididymo-orchitis caused by Enterobius vermicularis

Abstract

A rare case of epididymo-orchitis due to nematode infection by Enterobius vermicularis is reported. A 38-year-old male presented with right testicular pain. He was diagnosed with acute right epididymo-orchitis. Right epididymo-orchiectomy was performed. Microscopic examination showed parts of the body of the oxyurid in one section, thus confirming the diagnosis of pinworm infection. Although ectopic pinworm infections are broadly reported, testicular involvement is very rare. To our knowledge, this is the third reported case in the literature.
