Plexiform angiomyxoid myofibroblastic tumour is a recently described, rare, benign entity of the stomach.1–5 All the reported tumours were found in the gastric antrum or pylorus. The lesions usually had either transmural or muscularis propria involvement, which led to partial gastrectomy. Here, we report a female patient whose tumour was located in the gastric fundus and successfully removed by endoscopic resection.

A 54-year-old Chinese woman complained of persistent abdominal distension for over 3 months, accompanied by heartburn, hiccup, regurgitation and loss of appetite. Gastric endoscopy showed a 1.5×1.2 cm broad-based polyp-like mass in the gastric fundus (figure 1A). The biopsy was performed and was subsequently diagnosed as a plexiform angiomyxoid myofibroblastic tumour. Endosonography disclosed an irregular hypoechogenic mucosa and submucosa-derived mass protruding into the lumen (figure 1B), and an exploratory laparoscopy showed that the serosal surface had no significant findings. Finally, the patient was treated by endoscopic resection, and after 6 months' follow-up, she did not show any recurrence.
