An Unusual Gastric Polyp: Brunneroma.

Brunneromas or polypoid hamartomas are benign lesions arising from Brunner glands. They are usually benign lesions with low potential for malignancy. They are usually located in the duodenum and manifest with different unspecific symptoms, such as abdominal pain, nausea, or bloating. Other more serious manifestations are also reported in the literature that are related to the size of the lesion. Usually, they are treated with endoscopic resection, with some lesions requiring surgical intervention. We present a case of a gastric antral polypoid lesion that was consistent with Brunneroma on histology.
