title: An unusual urachal sinus with external opening in the midline suprapubic area.
abstract: Urachal sinuses usually manifest as umbilical discharge, but the authors experienced a case of unusual urachal sinus with external opening in the midline suprapubic area. The distal end of the sinus tract was found to extend directly to the median umbilical ligament. The histology shows a sinus tract lined with a modified transitional epithelium with surrounding inflammatory infiltrates. The authors believe that this is the first report of a urachal sinus with external opening other than the umbilicus in the English-language literature.
