Presence of accessory penis, colonic duplication and several other congenital anomalies in a child: a very rare association.

An accessory penis is a very rare anomaly. Only five cases have been reported thus far to our knowledge. We present the case of a child aged 2 years and 10 months who had a penis-like structure (containing phallus and glans) attached to the right buttock. Associated anomalies were a non-communicating type of colonic duplication, a paramedian stenosed anal opening, a horse-shoe kidney, posterior urethral valves, scoliosis of the lumbo-sacral spine, polydactyly and equino-varus deformity of the right foot. As far as we can tell, this is the first report of an accessory penis associated with colonic duplication and other congenital anomalies.
