Eggs containing larvae of Enterobius vermicularis in vaginal smear.

Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination. We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis.

Multiple focal nodular hyperplasia, an incidental finding on autopsy.

Focal nodular hyperplasia (FNH) is a benign condition of the liver often discovered incidentally on radiological investigation. Although FNH is a well-described lesion in the literature considerable diagnostic problems regarding this entity still remains. We report a case of multiple FNH in a 23-year-old male patient detected as an incidental finding in autopsy. On gross examination FNH was not suspected because of the multiple lesions and the lack of central scar which is characteristically described in FNH. The diagnosis was established on histopathology after examination of multiple sections of the lesions.
