Squamous cell carcinoma arising from abdominal wall defect lesion complicated with cloacal exstrophy

Cloacal exstrophy is an extremely rare congenital complex deformity that is associated with anterior abdominal wall defects, reflex and exposure of the cloaca (uninterrupted ureter and bowel), aproctia, a widely separated pubic bone, and defects or dysplasia of external genital organs. Here, we present the case of a 42-year-old man with squamous cell carcinoma arising from an abdominal wall defect complicated by cloacal exstrophy. He was successfully treated with excision of the skin lesion with the bowel and reconstruction using a pedicled anterolateral thigh FLAP combined with a tensor fasciae latae FLAP. To our knowledge, this is the first report of squamous cell carcinoma arising from an abdominal wall defect complicated by cloacal exstrophy.
