Exfoliative Esophagitis Early After Autologous Peripheral Blood Stem Cell Transplantation

Two patients with non-Hodgkin’s lymphoma (NHL) suffered from hematemesis due to exfoliative esophagitis early after autologous peripheral blood stem cell transplantation (PBSCT). The chemotherapy regimens used for these 2 patients were the same and consisted of high-dose ranimustine, carboplatin, etoposide, and cyclophosphamide (MCVC regimen), which have been widely used in autologous PBSCT for NHL in Japan. Esophageal bleeding in both patients was stopped by conservative treatment without any special endoscopic manipulations. Gastrointestinal bleeding after hematopoietic stem cell transplantation is usually caused by viral infections, graft-versus-host disease, or conditioning chemo-radiotherapy. Although severe esophagitis is common in patients receiving stem cell transplantation, the exfoliative form detected by endoscopic examination has not been reported. We conclude that high-dose chemotherapy and frequent vomiting during treatment are risk factors for lower-esophageal bleeding in these cases.
