Rev Esp Enferm Dig. 2024 Mar 12. doi: 10.17235/reed.2024.10375/2024. Online ahead of print.ABSTRACTA previously healthy 39-year-old woman was hospitalized with upper abdominal pain for 1-month duration. A semipedunculated protrusion with smooth surface was found at the gastric angle measuring 2.0 × 2.5-cm by gastroscopy. Endoscopic ultrasound (EUS) showed a hypoechoic mass originated from the mucosal layer. Abdominal computed tomography (CT) revealed a circular pedunculated and slightly low-density mass with mild enhancement in the stomach cavity. Endoscopic submucosal dissection (ESD) was performed. Postoperative histopathology examination revealed the tumor was composed of proliferated spindle cells with eosinophil infiltration which were around small blood vessels and mucosal glands arranged in an "onion-skin" appearance. Immunohistochemical analysis of the spindle cells showed CD34 was positive and CD117, S100, DOG-1, SMA, Desmin were negative. The patient was diagnosed as gastric inflammatory fibroid polyp (IFP) and no symptoms was observed in 12 months follow-up.PMID:38469826 | DOI:10.17235/reed.2024.10375/2024
