A 60-year-old woman diagnosed with cT2N0M0 esophageal cancer responded to chemoradiotherapy and had no metastasis or tumorigenesis for a year. She presented later with abdominal discomfort that lasted for 2 weeks. Upper gastrointestinal endoscopy found no esophageal abnormalities but gastric mucosal irregularities due to a cluster of erythematous, elevated lesions spreading from the fundus on the greater curvature of the upper body and anterior wall of the middle body. A biopsy showing the presence of mycelial threads led to a diagnosis of gastric candidiasis. Her symptoms and endoscopic findings improved after a 14-day oral fluconazole therapy. We report a rare case of gastric candidiasis, which showed typical endoscopic findings of candidiasis associated with ulcerations, and review the literature on gastric candidiasis.
