Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) in the elderly was revised from the category EBV-positive DLBCL not otherwise specified in WHO 2017. The prognosis of this lymphoma is very poor. We report a case of an 82-year-old woman diagnosed with gastric EBV-positive DLBCL (WHO 2008). Gastroduodenoscopy revealed multiple ulcers and fold thickening. She was followed-up without any treatment because of her old age. Repeat endoscopy one year and eight months later revealed a single ulcer with no lymphoma cells found in a biopsy specimen. Two years later, the lesion had spontaneously disappeared.
