Sporadic Isolated Aplasia Cutis Congenita

Objective: As shown in published literatures, aplasia cutis congenita (ACC) is an uncommon anomaly among newborns and is often overlooked when the lesion is small. We report a case of ACC accidentally found at birth. Case Report(s): A 31-year-old female, gravida 2 para 1, came to the hospital at 38 weeks and 6 days of gestation. She received regular prenatal care and the results of all tests were normal. Elective cesarean section was perlormed smoothly and a seemingly healthy male baby was born. Initial physical examination of the baby showed a round lesion sized 1 cm in diameter just over parietal area, near the vertex of the head. The floor of the lesion was bone, and aponeurosis can be seen. No protruding brain tissue or meninges were noted. Wound care with antibiotic ointment was undertaken for this lesion, and it healed in a week with only some fibrotic tissue left. Conclusion(s): Aplasia cutis congenita is easily ignored when the lesion is small. A thorough examination is indicated in all newborns for any skin lesion and other accompanying anomalies. While surgical repair is necessary for large and complicated defects, pure skin lesions could be easily managed by conservative treatment of antibiotics and wound care.
