ABSTRACT
A 48-year-old man was admitted to our hospital complaining of acute severe abdominal pain and constipation. He had received bone marrow transplantation for acute myelogenous leukemia 5 months previously and immunosuppressant treatment for chronic graft-versus-host disease. Abdominal X-ray and CT scan films revealed his large intestine widely dilated and filled with air, and colonic pseudo-obstruction was diagnosed. It was difficult to ascertain the cause of the symptoms until 6 days after onset of the abdominal pain when disseminated zoster eruption appeared over his whole body. It was disseminated varicella-zoster and complicated with colonic pseudo-obstruction. He was treated with acyclovir. It is important to suspect disseminated varicella-zoster and treat early immunocompromised patients complaining of severe acute abdominal pain and colonic pseudo-obstruction.
