1/25. Unilateral salpingitis due to enterobius vermicularis.

    A case of unilateral salpingitis caused by enterobius vermicularis presenting as a painful adnexal mass in a 28-year-old woman is reported. ( info)

2/25. Cytologic diagnosis of enterobius vermicularis eggs in an enterocutaneous fistula.

    A middle-aged female underwent a laparotomy for suspected ovarian cancer and developed a discharging sinus in the right iliac fossa. Smears of the discharge showed helminthic eggs which were characterised as those of enterobius Vermicularis. The possibility of an enterocutaneous fistula was suggested which was subsequently confirmed during a relook laparotomy. ( info)

3/25. Eosinophilic ileocolitis secondary to enterobius vermicularis: case report.

    We describe an unusual presentation of enterobius vermicularis infestation. Computed tomography showed wall thickening in the distal ileum and cecum, with fat stranding, ascites and mesenteric adenopathy. Fluoroscopic examination confirmed distal ileal transverse fold thickening. Isolation of enterobius vermicularis in stool and biopsy confirmed the diagnosis. enterobius should be included among the causes of eosinophilic ileocolitis. ( info)

4/25. Pelvic abscess from enterobius vermicularis. Report of a case with cytologic detection of eggs and worms.

    BACKGROUND: enterobius vermicularis is known to produce perianal and ischioanal abscesses and invade the peritoneal cavity via the female reproductive system, causing pelvic peritonitis. However, there are only rare case reports on the cytodiagnosis of these parasitic lesions. CASE: A 28-year-old woman was admitted with a tender left iliac fossa mass and greenish vaginal discharge. Ultrasonogram and computed tomography scan confirmed the presence of a mass lesion suggestive of a tuboovarian abscess. Cytologic examination of the pus obtained during left salpingo-oophorectomy revealed the presence of ova of E vermicularis and fragments of the adult worm in an inflammatory exudate consisting predominantly of neutrophils, eosinophils and occasional epithelioid cell granulomas. paraffin sections of the tuboovarian mass showed necrotizing epithelioid cell granulomas, but neither ova nor any worm section was identified. Although the possibility of tuberculosis was considered histologically, Ziehl-Neelsen (Z-N) stain for acid-fast bacilli was negative. Z-N staining of the smear and mycobacterial culture of the pus also did not yield positive results. CONCLUSION: E vermicularis may cause tuboovarian abscess with necrotizing epithelioid granulomas mimicking tuberculosis. Cytologic examination of the pus is helpful in the diagnosis. ( info)

5/25. Laparoscopic appendectomy in children with enterobius vermicularis.

    As surgeons gain more experience with laparoscopy in children, it is becoming apparent that one of the best applications of the technique is for appendicitis. The advantages of laparoscopic appendectomy include a better cosmetic result, particularly in young female patients, a shorter recovery time, and an early return to normal activities. In the differential diagnosis of appendicitis, the association of enterobius vermicularis (pinworms) inflammation in the pediatric age group is not uncommon. The endo-loop technique for laparoscopic appendectomy is the standard technique used in our department. In three patients with E. vermicularis undergoing appendix removal using this technique, pinworms were found to be set free into the abdomen after dividing the appendix between the loop ligatures. Bipolar coagulating forceps were used carefully to thermally desiccate the worms, which were then removed using a blunt grasper. E. vermicularis being released into the abdomen in children undergoing laparoscopic appendectomy using the endo-loop technique has not been reported. Careful evaluation of the appendix stump and simple but careful thermal desiccation and removal of pinworms, if present, must be considered when using the endo-loop technique. ( info)

6/25. pelvic inflammatory disease associated with enterobius vermicularis.

    A case of pelvic inflammatory disease in a sexually non-active 13 year old girl is described, with evidence of pinworms as the cause. albendazole treatment cleared the infestation but the patient suffered subsequent bouts of lower abdominal pain. The literature is reviewed regarding abdominal pathology associated with ectopic migration of pinworms. ( info)

7/25. A case of ovarian enterobiasis.

    A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10 cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis. ( info)

8/25. Detection of enterobius vermicularis eggs in the submucosa of the transverse colon of a man presenting with colon carcinoma.

    We report a case of a chronic infiltrate of the intestinal wall of the transverse colon by the eggs of enterobius vermicularis in a man who had immigrated to taiwan from mainland china 50 years ago. During surgery for suspected transverse colon carcinoma, histologic examination of the tumor mass revealed eggs of E. vermicularis embedded in granulation tissue in the submucosa of the transverse colon. Results of a stool examination were negative for eggs but strongly positive for occult blood. The mass in the transverse colon was completely removed during surgery. At the present time, the patient remains asymptomatic. ( info)

9/25. Perineal nodule due to enterobiasis: an aspiration cytologic diagnosis.

    Subcutaneous swelling due to Enterobious vermicularis infection is rare. Their presence in perineal subcutaneous tissue is unusual and a clinical curiosity. A case of subcutaneous nodule in the perineum due to E. vermicularis infection diagnosed on fine-needle aspiration is described. Tissue reaction was granulomatous with neutrophils and eosinophils. Lack of familiarity with the morphology of parasites or its eggs, degeneration, and inadequate sampling may make the diagnosis difficult. This case report provides the morphologic clues to cytopathologists toward rendering a diagnosis and alerts them to the possibility of parasitic infection in unusual locations. ( info)

10/25. Dipylidium caninum in an infant.

    The tapeworm, Dipylidium caninum, occurs worldwide in dogs and cats. It may occur rarely in children, when the infection may be unrecognised or misdiagnosed. We report such a case. ( info)
