Inlet patch mimicking unstable angina pectoris.

The ectopic stomach mucosa island in the proximal esophagus, which is generally known as the inlet patch or cervical inlet patch, is called as the heterotopic gastric mucosa of the esophagus. Despite its asymptomatic progress, it may cause chest pain, shortness of breath and difficulty in swallowing due to the acid secretion from the ectopic mucosa. The study aimed to present a patient who underwent coronary angiography with an unstable angina pectoris diagnosis by cardiologists for gastric chest pain but found an inlet patch in gastroduodenoscopy.
