title: Urachal cyst associated with a suprapubic sinus.
abstract: Urachal anomalies are frequent and may exhibit many anatomical variations. We report a case of a urachal cyst that had a sinus tract extending to the lower abdomen just above the pubic symphysis. Histologic examination of the specimens showed a squamous-epithelium-lined sinus tract and a columnar-epithelium-lined cyst, which suggested a developmental disorder. This may be an extremely rare case where the urachal cyst opened into the suprapubic sinus.
