title: Severe acute visceral pain from varicella zoster virus.
abstract: Varicella zoster virus infection often will not present in the characteristic dermatomal distribution of vesicles in patients who have undergone bone marrow transplantation. We cared for a 51-yr-old man with severe abdominal pain after bone marrow transplantation for non-Hodgkin's lymphoma. The diagnosis of varicella zoster was not entertained until he developed a diffuse vesicular rash several days after the onset of pain. We report this case to alert others who may be consulted regarding pain management options for similar oncology patients.
  
  
  CONCLUSIONS
  We report a patient with lymphoma, prior bone marrow transplant, and acute visceral pain for whom IV opioids in large doses proved inadequate. An interventional pain management technique was considered until characteristic varicella vesicles appeared over the patient's trunk. We report this case to alert others who treat oncology patients that the diagnosis of visceral zoster should be considered when patients who have undergone bone marrow transplantation present with severe visceral pain.
