Key Clinical Message

IgG4-related diseases rarely affect the gastrointestinal tract. We reported a 44-year-old man who presented with a solitary gastric mass and was ultimately diagnosed with food-specific IgG4-related gastrointestinal disease. Following surgery and dietary intervention, no recurrence was observed within six months.
