Abstract
PDF - Enterobius vermicularis is one of the most common parasites found in the intestine of humans. The gravid female worms migrate outside the anus to release eggs on the perianal skin. Rarely, they migrate to the genitourinary tract in female patients. We present a case in which pinworm eggs were found in a cervicovaginal smear of a 37-year-old woman. The eggs were elongated oval shaped and flattened on one side. The thick, double contoured birefringent shell stained bright yellow or orange. Some coarsely granular embryos or curved larvae were enclosed in the refractile shell. Empty eggs or wrinkled shells with clumped granular material were also present. Although pinworm eggs are easily identified because of their characteristic morphologic appearance, careful screening is needed due to the frequent masking by inflammatory cells.

Abstract
PDF
- The intestinal nematode Enterobius vermicularis is the most common metazoan endoparasite in humans, with humans being the only host. But complicated perianal granulomas due to Enterobius are unusual. The literature reports only 13 previous cases of enterobiasis presenting as perianal mass or abscess. We describe an additional case of a perianal mass caused by granulomatous inflammation containing Enterobius vermicularis eggs and dead bodies in a 7-year-old boy. The lesion was located in the anus and measured 2 1 cm. Clinical impression was lipoma and excisional biopsy was done. Microscopic examination revealed necrotizing granuloma which contained several 50~60 20~30 micrometer sized eggs which were identified as those of Enterobius vermicularis. The adult worm could not be identified with clarity due to necrosis.
