Gastric adenomyoma: an uncommon cause of dyspepsia and a rare endoscopic finding

Background: Gastric adenomyoma (GA) is a rare benign lesion comprising of ducts and glands embedded in smooth muscle stroma. Thirty-seven (37) cases of GA were identified until 1993, however, only 15 cases are said to have been reported from 1993 to 2016. Esophagogastroscopy has been widely used in evaluating GA. However, the diagnosis of GA remains exclusively histological. Case: We report a 26-year-old Nigerian woman who presented with recurrent dyspepsia with her endoscopic findings suggestive of GA. GA was confirmed by histology, and she was managed conservatively. Conclusion: This report will contribute to creating awareness of this uncommon condition and also reminding physicians in considering GA as a possible differential of dyspepsia.
