Pygomelia with genitalia duplication at Treichville Teaching Hospital: two new cases

Abstract

Pygomelia is a rare deformity (1/100 000) defined by the presence of one or more supernumerary members in the pelvic region. In this article, we report two new cases, including one that was successfully operated upon in our unit. The first case was characterized by the presence of two additional lower limbs postioned in the hypogastric region and a third vestigial epigastric upper limb associated with visceral deformations. Surgical treatment was successfully accomplished. The clinical examination of the second case objectified the third lower limb at the level of the left buttock with a rudimentary pelvis, a sacrococcygeal teratoma, and a genital duplication. The newborn child died during the investigations. The nosological limits of pygomelia are still poorly specified because it is similar to cases of duplication of the lower limbs and dipygus.
