Atresia of the appendix.

A 4-day-old black male underwent laparotomy for intestinal obstruction. At surgery, multiple jejunal atresias (type IV) of the jejunum were detected. As an incidental finding, atresia of the appendix was also present. The jejunal atresia was repaired, and resection of the tip of the cecal pole and atretic appendix was performed. Gross and histological examination confirmed the presence of a type IV atresia of the jejunum and a cordlike (type II) atresia of the appendix with inflammatory changes in the tip of the appendix. The boy made an uneventful recovery. Examination of all organ systems did not show any associated findings, and the family history was unremarkable. To our best knowledge, this case represents the first case of atresia of the appendix described in the literature.
