It is reported that the prognosis of relapse nasal lymphoma is invariably fatal, and high-dose chemotherapy using autologous peripheral blood stem cell transplantation (auto-PBSCT) has been established as an effective treatment for patients with relapsing aggressive non-Hodgkin's lymphoma. We experienced a case with T-cell lymphoma in the nasal cavity that relapsed after the initial treatment consisting of chemotherapy and radiation therapy. We treated with high-dose chemotherapy and auto-PBSCT to the patient. The patient has been disease free without therapy for 30 months following auto-PBSCT. Our experience suggests that high-dose chemotherapy using auto-PBSCT may be one of effective treatment option for relapsed nasal T-cell lymphoma when conventional chemotherapy fails.
