Epididymitis from Enterobius Vermicularis: Case Report

Abstract

A rare case of epididymitis caused by Enterobius vermicularis, a pinworm, is reported. A 52-year-old man underwent resection of the right epididymis and histological examination confirmed the diagnosis of pinworm infection by discovering parts of the body of the oxyurid in various sections.

Enterobiasis in Ectopic Locations Mimicking Tumor-Like Lesions

“…In female subjects, E. vermicularis can sometimes take another path and be found in the genitals, going from the vulva back up to the Fallopian tubes [11, 12], sometimes reaching the ovaries [13, 14] and also having the capacity of penetrating the surrounding peritoneum [15]. Other times, both in female and male patients, the parasite can go astray into rare ectopic locations such as the tissues of the perianal region [16–18], the prostate [19], the urinary bladder [20], the ureter [19], the spleen [21], the peritoneum [22, 23], the mucosa and/or the appendicular lumen [23, 24], the intestinal wall [25], the liver [26, 27], the lungs [28, 29], the epididymis [30], and the conjuntival sac [31]. In such cases, clinical diagnosis is impossible, and the diagnosis can only be reached histologically, generally representing an unexpected surprise for the histopathologist.…”

Bile duct infestation with Enterobius vermicularis diagnosed after cholecystectomy: About two case reports

“…After molting twice, the worms copulate and then migrate downwards to the large intestine, where they can be found in large numbers particularly in the cecum, appendix or ascending colon. 6 Very rarely, incidental involvement of other organs occurs (<1% of cases), 6 it can involve the retrocecal tissues, the peritoneum, 7 the genital female and male tract 8 , 9 , 10 and less frequently the liver. 11 There are isolated case reports of infection involving the salivary glands, 12 nasal mucosa, eye, 13 skin, 14 and lungs, 15 presumably due to autoinoculation of these sites with eggs or adult worms from the intestinal tract.…”

Persistent scrotal pain and suspected orchido‐epididymitis of a young boy during pinworm (Enterobius vermicularis) infection in the bowel

“…Pinworms live in the gastrointestinal tract, and they take advantage of the contents of bowel. They can migrate to genitourinary tract, and cause uretritis, pyelitis, salpingitis, endometritis and epididymitis (1,4). Our patient suffered symptoms of orchido‐epididymitis that we supposed to be caused by pinworm.…”

“…Urinary tract infection, salpingitis, endometritis, pyelitis and – notably – appendicitis have been reported as infrequent manifestations of pinworm, and it has been found in lung, breast, Meckel′s diverticle, liver and spleen, as well (1). It is even able to cause epididymitis (4). We report persistent scrotal pain among a young boy.…”
