Nematodes are probably the most widespread and abundant group of animal often occurring in huge numbers in very diverse environments. The largest number of helminthic parasites of humans belongs to the phylum nematoda and Ascaris lumbricoides is the most common of human helminthic parasites. Commonly known as roundworm, Ascaris lumbricoides is cosmopolitan, especially prevalent in the tropical countries like India. The adult roundworm commonly lives in small intestine, retaining its position by the virtue of its own muscle tone. Eggs of roundworm are bile stained, appearing yellowish brown in colour. Roundworm is a restless wanderer, showing great inquisitiveness as it tends to move itself from the original site, and get into any aperture it may find on its way. So it?s quite possible to encounter this commonest and largest intestinal nematode of humans at some odd sites in the body. Here, we are presenting a very rare case of finding colourless (i.e., non bile stained) eggs with a female roundworm isolated from an ectopic site.
