“…The diagnosis is based on the histological finding. In two cases, the diagnosis was cytological, with typical eggs having been found by means of fine needle aspiration [39, 40]. Among the other granulomatous lesions which may be confused with perianal lesions from E. vermicularis are those due to tubercular nodules, leiomyomatosis nodules, and granulomas from foreign body.…”

Both the clinical and the histopathological diagnostic difficulties of oxyuriasis in unusual sites and their importance from a clinical point of view are pointed out. The authors report two ectoptic cases of enterobiasis observed in Northern Italy, one located in a fallopian tube of a 57-year-old woman and the other in a perianal subcutaneous tissue of a 59-year-old man, mimicking tumor-like lesions. The authors take advantage of the occasion to focus the attention of the medical world on this subject, lamenting the scarce importance given to this parasitosis in university courses of medical schools and in medical textbooks as it is incorrectly considered “out-of-fashion.”

“…The only case of subcutaneous abscess due to enterobiasis diagnosed by FNA cytology was located in the natal cleft. 3 Avolio et al 13 described one case and reviewed 12 other cases of perianal abscesses reported up till then. All 13 cases were located within the anal triangle of perineum at or near the anal verge and diagnosis of EV infection was established postoperatively in histologic sections.…”

“…Cuticular plates of body wall seen in our case resembled that reported earlier. 3 Lack of familiarity with the morphology, poor preservation of worms, eggs, and inadequate sampling may make the cytologic diagnosis difficult. Any of these could be responsible for missed diagnosis at first FNA in the present case.…”

“…1,2 However, such a swelling due to the eggs of intestinal parasites has rarely been diagnosed and documented. 3 The ease with which cytological specimens are procured has resulted in the need for rapid and accurate interpretation to ensure prompt treatment.The present article describes a rare case of subcutaneous nodule in the urogenital triangle of perineum, far from the usual site of the perianal region in which eggs and body parts of the adult worm of Enterobius vermicularis (EV) were detected on fine-needle aspiration (FNA). The aim is to highlight the unusual clinical presentation and uncommon cytological features.…”

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.
