Congenital scrotal sinuses are extremely rare midline raphe anomalies in children. Quite few cases are published in the literature up to date. Their etiology is unclear but similar to the perineal midline cystic defects it is believed that during the early phases of embryogenesis they could arise from trapped epithelial cells as a result of incomplate closure of epithelial folds. https://unitedssports.shop/product-category/fan-shop-cresting-kits/
