Summary

Epstein-Barr virus mucocutaneous ulcer (EBVMCU) is a rare form of EBV lymphoproliferative disorder. The disease was recently described in 2010 for the first time in a case series and it was recently identified by the WHO classification of haematological malignancies as a separate category among the EBV lymphoproliferative disorders. We present a case of EBVMCU of the colon presenting as an ulcerating inflammatory mass in a female in her mid-60s who presented initially with abdominal pain and diarrhoea. The patient had extensive workup for her disease and due to progression of her symptoms, she was taken for an exploratory laparotomy. During the procedure, there was an inflammatory mass at the caecum and severe inflammation of the caecum and the terminal ileum and right hemicolectomy was performed. Diagnosis was confirmed by histopathology as EBV-positive lymphoproliferative disorder best classified as EBV-positive mucocutaneous ulcer.
