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.

Assessment of frequency, transmission, and genitourinary complications of enterobiasis (pinworms).

BACKGROUND: Pinworms are the most common helminth infection in the USA and Western Europe, with prevalence rates in some communities of as high as 30-50%. Pinworms generally live in the gastrointestinal tract, and helminth infestations have been noted in over one-quarter of acute appendectomies on histologic examination. RESULTS & CONCLUSIONS: Although transmission is often attributed to the ingestion of infective eggs by nail biting and inadequate hand washing, inhalation and ingestion of airborne eggs also occur. The female Enterobius vermicularis migrates nightly to the perianal area to deposit her eggs, but some worms find their way into adjacent orifices, most commonly the female genitourinary tract, producing an array of symptoms. More consideration of this entity is justified in patients presenting with genitourinary complaints not responding to normal therapies. In the treatment of pinworms affecting genitourinary organs, treatment with possibly two oral agents, namely mebendazole and ivermectin, and a topical therapy for the eggs may be warranted.

A longitudinal study of enterobiasis in three day care centers of Havana City.

Pinworm infection was prospectively studied during one year in 469 children attending three day care centers. Each child was examined at six months intervals using up to three perianal swabs with adhesive tape. Those found infected were treated with mebendazole. At the beginning of the study we found a prevalence of 28% that dropped to 13% and 12% in the following study periods. The reinfection rate was twice the incidence rate in both study periods. We also found a small percentage (10%) of the children reinfected in most or all study periods. There was a high correlation between reinfection and perianal itching. Our results add further knowledge to the epidemiology of intestinal parasites in day care centers.
