Abstract

An unusual over-gravid female of Enterobius vermicularis was recovered from a 15-month old child by cello-tape anal swab. The patient resided in Inchon and complained of severe anal itching. The worm measured 7.8 mm in length and 0.5 mm in width, and retained typical morphologic features of E. vermicularis such as cephalic alae and a sharply pointed posterior end. In this gravid female, peculiarly, the uterus was tremendously distended, and about 99% of the whole body length was completely packed with a great number of eggs. Other internal organs were difficult to observe. This paper describes a peculiar over-gravid female of E. vermicularis.
