Congenital skin aplasia affecting trunk.

A male infant was born at term, weight 2 8 kg. Birth had been uneventful. Clinical examination showed no abnormality except bilateral thoraco-abdominal skin defects, each lesion measuring 5 x 4 cm. Beneath the thoracic part of the defect could be seen ribs with partially developed intercostal muscles, and deeper still the pleura and underlying lungs on both sides were visible, while beneath the abdominal part of the defect the peritoneum with underlying viscera could be seen. There was no history of such defects in the family and the pregnancy had been normal. A policy of conservative management was adopted, the defect being dressed with Gelonet gauze after cleaning the surrounding skin with chlorhexidine. No antibiotics were given. There was gradual epithelization of the defects (Fig. 1), which was complete in 8 weeks (Fig. 2) and the baby was then discharged from hospital.
