1/28. oxyuriasis-induced intestinal obstruction in a child--case report.

    PURPOSE: The presentation of an unusual case of the tumor of ileum wall induced by pinworm infection in a 5-years-old child. MATERIAL AND methods: The record of a 4-years-old boy treated in the department of pediatric surgery was analyzed concerning the diagnostic difficulties. After 6 month from an episode of ileo-cecal intusussception successfully treated with a barium colon enema, the diagnosis of lymphoma was made and the resection of distant segment of small intestine was performed. RESULTS: No clinical and laboratory features of oxyuriasis could be stated before the onset of disease, during hospitalization and in the follow-up period. The hypertrophied and activated lymphatic tissue with a non-specific inflammatory reaction to the pinworms were seen in the wall of ileum, appendix and mesenteric lymph nodes. No neoplastic cells were found in the microscopic study of ileum, appendix, mesenteric lymph nodes and peritoneal lavage fluid. CONCLUSIONS: The proper diagnosis of oxyuriasis may be difficult when the course is atypical. The enterobius vermicularis infestation as an etiologic factor should be taken into account in any case of abdominal pathology. However, the methods routinely used in "acute abdomen" including examinations of blood, urine and stool, repeated ultrasound and CT, are not reliable. As the infestation may mimic neoplasm, the surgical treatment and microscopic examination can be necessary for the final diagnosis in some cases. ( info)

2/28. enterobius vermicularis salpingitis: a distant episode from precipitating appendicitis.

    Chronic pelvic inflammatory disease is a common gynecologic diagnosis in women with chronic pelvic pain. When standard antimicrobial therapy does not improve the clinical status, uncommon diagnoses such as enterobius vermicularis should be considered. In this case, E vermicularis presented as acute and chronic salpingitis in a patient who had had E vermicularis-related appendicitis 5 years earlier. ( info)

3/28. Ectopic enterobiasis: a case report and review.

    enterobius vermicularis ('pinworm') is rarely found outside the gastro-intestinal tract. We describe a case of extra-intestinal pinworm abscess associated with an inguinal hernia in an adult. A brief review of the literature is given and possible mechanisms of tissue invasion are discussed. ( info)

4/28. epididymitis from enterobius vermicularis: case report.

    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.

5/28. enterobius egg granuloma of the vulva and peritoneum: review of the literature.

    Two cases of enterobius granuloma containing eggs only are reported. The first case involved the vulva, where no such granuloma has been reported previously. The coexistence of peritoneal granuloma and rectal adenocarcinoma in the second case suggests the possibility of direct penetration of the damaged colonic wall by the parasite, as emphasized by several previous reports of neoplastic involvement and perforation of the intestinal wall in cases of ectopic infections. The diagnostic criteria of enterobius eggs granuloma, which might be a diagnostic dilemma for pathologists who are not familiar with such criteria, are described herein. ( info)

6/28. enterobius vermicularis.

    The benefits of a ring flash in photographing an orifice can be seen in this interesting case where the main subject area is clearly visible. When photographing minors, the legal implications of the subject material needs to be considered to avoid contravening the Protection of Children Act. ( info)

7/28. Hepatic granuloma resulting from enterobius vermicularis.

    A nodule of the liver was incidentally noted during left colectomy for a large villous adenoma in a 74-year-old man. Microscopic examination disclosed a granuloma of the liver containing numerous enterobius vermicularis ova and a cross-section of the nematode. This is the fourth reported case of hepatic oxyuriasis and the second case reported in north america. ( info)

8/28. Pinworm infestation of the genital tract.

    Extraintestinal enterobiasis has been reported in the vagina, endometrium, myometrium, ovary, fallopian tube and pelvic peritoneum. Gravid female pinworms may migrate from the perianal area to the vagina, ascend through the genital tract and exit through the fallopian tube to the peritoneum. Ectopic enterobiasis seldom causes clinical symptoms, but chronic granuloma formation may simulate other mass lesions in the pelvis. ( info)

9/28. Disseminated intraperitoneal oxyuris granulomas.

    The threadworm, enterobius (oxyuris) vermicularis, is an nematode which may inhabit the human terminal ileum, colon and appendix. Its presence in ectopic sites is uncommon. We describe a case of generalized intraperitoneal oxyuris granulomas detected as an incidental finding at laparotomy for tuboovarian abscess. ( info)

10/28. Invasion of human embryo by enterobius vermicularis.

    Two enterobius vermicularis organisms invading a macerated embryo 2 cm in length were found in the tissue from an endometrial curettage performed for missed abortion in a pregnant woman. Ova from the helminths were recovered from the vagina and endometrium of the patient. This most unusual case provides further evidence for the invading capacity of E vermicularis. ( info)
