 Resumo

A Heterotopia Gástrica no esófago é uma entidade frequente, normalmente assintomática. Na maioria das situações representa a presença de pequenas áreas de mucosa plana com glândulas fúndicas situadas no esófago superior. Os autores apresentam um caso de heterotopia gástrica revelando-se sob a forma de um pólipo esofágico composto por epitélio do tipo antral. A remoção endoscópica da lesão permitiu a resolução clínica e sintomática no caso descrito.

Heterotopic Gastric Mucosa in the esophagus is a frequent, though usually asymptomatic condition. Most of the cases present as a flat area of the fundic-type gastric mucosa in the upper esophagus. We present a case of a polypoid heterotopic gastric mucosa with an antral pattern. Endoscopic removal of the lesion provided clinical relief and cure.
