Acute Incarceration of Umbilical Excessive Skin

Abstract

A 3-year-old girl was brought to the emergency department of our hospital presenting with redness and inversion of the skin at the umbilical portion. No hernial orifice was palpable and the excessive skin inversion was easily relieved by pushing it back. Ultrasonographic examination showed no tubular structure that could suggest a urachal remnant, and the cause of the symptoms was unclear at that time. The same symptoms recurred two days later, and she underwent surgical exploration. The skin at the umbilical region excessively grew and folded around the subcutaneous space. When it was pulled out under general anesthesia, the same incarcerated state could be reproduced. There was no hernial orifice or dermoid cyst. The excessive skin around the umbilical region was excised and reconstructed. Her postoperative course was uneventful. The extraordinary surplus skin of the umbilical portion was the characteristic feature in this case; furthermore, the fact that the patient could invert the surplus skin by herself was uncommon. The cause of this condition is as yet unclear.
