Abstract

Plexiform fibromyxoma is a relatively new pathological category that consists of a rare group of non-gastrointestinal stromal tumors with a peculiar plexiform growth pattern. We report a case of gastric plexiform fibromyxoma in a 60-year-old man. Gastroscopic examination revealed a gastric submucosal tumor in the antrum. Magnetic resonance imaging (MRI) showed a nodule with distinct signal hyperintensity on T2-weighted images, with strong enhancement peripherally in the early phase to the entire lesion in the delayed phase. Endoscopic ultrasound-guided fine-needle aspiration cytology was performed, and the cytological diagnosis was spindle cell tumor, so partial gastrectomy was performed under a preoperative diagnosis of GIST. The resected tumor demonstrated plexiform architecture, myxoid stroma, prominent vasculature, and spindle cells, reflecting the characteristic findings on MRI. This is the first report to describe radiological findings for gastric plexiform fibromyxoma.
