A male, aged 60 with rheumatoid arthritis which was treated with prednisone, developed a severe symptomatic stomal gastritis at the site of a previous Polya partial gastrectomy. The endoscopic appearance of the lesion was similar to that of Candida infection, which is more frequently seen in the oesophagus. Candida albicans was cultured from biopsy specimens, and prompt resolution of the lesion and the patient's symptoms occurred with orally administered antifungal therapy. Primary gastric candidiasis should be considered in compromised patients with symptoms of infection of the upper part of gastrointestinal tract.
