Difalia, uma anomalia congênita que promove alterações morfológicas : uma revisão de literatura

Abstract

Diphallia or bifid penis is a rare anomaly that can occur in humans and animals. This congenital anomaly change the reproductive tract functioning which required surgical procedures. The purpose of this study was to perform a systematic review of the occurrence of bifid penis in children and adults between 2000 and 2013. A bibliographic review was performed by the databases PubMed, Science Direct, SciELO, LILACS and Bireme in which classical, recent and relevant studies were selected to discussing of the subject. It was concluded by this study that reports of Diphallia are extremely scarce in the literature, especially in Western countries, as Brazil, where we found no scientific reports. Furthermore, no important studies that had performed Karyotype tests of the evaluated patients to identify a possible molecular marker which characterizes the genesis of this congenital anomaly were found.
