Congenital duplication of the lower extremity is quite rare. Only 26 cases have been reported so far. A female infant with incomplete duplication of lower limb and with hypothyroidism was reported. Her mother's pregnancy and delivery was uneventful. A tube-like skin tissue was found on the posterior aspect of the infant's left thigh. Her left foot presented equinovarus deformity. There were three extra toes on the plantar side of her foot. A band of skin with a thin horny layer, similar to the dorsal surface, could be seen on the sole. The skin tube on the thigh was simply resected. A neuro-vascular-islanded toe was made from the plantar toes and rotated to restore five toes on the foot. The transferred toe thrived in accordance with the surrounding toes. The patient could run without difficulty at the age of 3. Previous reports about this case are summarised and reviewed here.
