The frequency of thoraco- omphalo-ischiopagus tripus or conjoined twins (CT) is quite rare of mozygotic twinnings, and they are classified as unions of symmetrical CT. A case of conjoined twins with thoraco- omphaloischiopagus type is presented here as well as a review of differential diagnosis. The twins had two heads, two pairs of upper limbs and three lower limbs. They also shared thorax, abdomen and pelvis with a single beating heart.
