Heterotopic gastric mucosa and intestinal atresia in a neonate.

Jejunal atresia is a well-known congenital malformation attributed to in utero ischemic events. Heterotopic gastric mucosa (HGM), or gastric tissue present in a location other than the stomach, is a much rarer congenital anomaly and is generally found in the esophagus or within a Meckel's diverticulum. Identifying both within the same pathologic specimen is truly rare.
