Perianal threadworm dermatosis – http://id.who.int/icd/entity/1855825638

Perianal irritation and inflammation resulting from infestation of the lower digestive tract by the parasitic roundworm Enterobius vermicularis, also known as threadworm or pinworm. The female worms leave the rectum at night to deposit their eggs on perianal skin. Vaginal irritation may occur if the worms migrate to the vagina instead of returning to the rectum. Transmission is by ingestion of eggs, which are readily transferred to the hands and mouth.
