Perianal Granuloma due to Enterobius vermicularis / 대한피부과학회지

Enterobiasis is a common disease among school-aged children, with worldwide distribution and high prevalence in countries with a temperate climate. Enterobius vermicularis usually inhabits the intestinal lumen, and the majority of clinical presentations are perianal pruritus. Extraintestinal infection is uncommon, mostly involving the female genital tract. It has been reported to occur in the peritoneal cavity, ovary, fallopian tube, endometrium, lung, liver, urinary tract and perianal tissue. In Korea, there has been only 1 case of enterobiasis presenting as perianal abscess in the Korean pathologic literature. So we present here an unusual case of perianal granuloma by Enterobius vermicularis in a 62-year-old woman.
