Incidental finding of esophageal inlet patch: A case report.

An esophageal inlet patch is a congenital anomaly composed of heterotropic gastric mucosa at or just distal to upper esophageal sphincter. Most often it is asymptomatic or presents as complications of acid secretion. The diagnosis is confirmed by endoscopy with biopsy. We have presented a case of 67 years old female who complained of nausea and decreased appetite. Endoscopy showed an elevated mucosal structure with superficial ulceration in the upper third of esophagus. Histopathology confirmed presence of ectopic gastric mucosa. We have presented this case as it is not diagnosed often and it is important to identify it as it helps the treatment and rarely has a malignant potential.
