[Pygomelus. An African surgical case report].

Pygomelus is a malformation characterized by the presence of one or more extra-extremities in the pelvic region. This article describes a case of pygomelus involving a child in Cote d'Ivoire. It is the tenth operated case to be reported in the literature. The malformation consisted of a well developed third lower extremity attached to the right iliac crest, without a rudimentary pelvis, and of a poorly developed upper extremity attached to the subpubic region. The two extra-extremities were removed surgically without complications. Pygomelus is an uncommon malformation whose nosologic limits are unclear since it is comparable to lower extremity duplication and dipygus. According to the authors pygomelus is a more appropriate term than caudal duplication which is widely used in English-speaking physicians.
