The first male with thoracoschisis: case report and review of the literature.

A male infant presented at birth with intestine and liver herniated through a defect 3 cm below the left nipple on the anterior thoracic wall. Riedel lobe, attached to the left liver lobe, and the transverse colon were seen protruding through the defect at the region of the left eighth intercostal space at surgery. A fibrous band extending from the lower defect border to the bladder was present. The hernia content was reduced inside the abdomen and the fibrous band, and Riedel lobe and necrotic-appearing omentum were excised. Thoracoschisis is a very rare congenital anomaly with only 4 cases reported. This is the first isolated thoracoschisis case without an accompanying diaphragmatic hernia.
