High clinical suspicion is required, as failure to diagnose EBV mucocutaneous ulceration may result in significant morbidity and mortality. We report the case of a 64-year-old female renal transplant recipient requiring admission to hospital for management of severe oral and epigastric pain. Examination revealed a large, superficial, well-circumscribed ulcer at the base of the tongue. Blood tests suggested a secondary immunodeficiency characterised by mild leucopenia, hypogammaglobulinaemia, and low memory B-cells with normal immunophenotype. Endoscopy revealed four, cratered ulcers in the pre-pyloric region of the stomach. A core biopsy of the tongue ulcer confirmed EBV mucocutaneous ulceration. The patient’s immunosuppression was optimised, which resulted in complete resolution of the tongue and gastric ulcers at eight and twelve weeks of follow-up respectively.展开更多
