A 56-year-old man had an endoscopic examination for dysphagia in March 2007 which revealed tumors in the esophagus and stomach. Pathological examination of the esophagus biopsy specimens showed an unspecified peripheral T cell lymphoma. The esophagus tumor was tolerant to CHOP and EPOCH therapy. After an autologous peripheral blood stem cell transplantation, a complete response was observed in the patient. However, a lymphoma relapse was diagnosed in the lung in September 2008. The relapsed lung lymphoma was tolerant to EPOCH therapy. The refractory pulmonary peripheral T cell lymphoma was remarkably reduced by PEGS therapy. PEGS therapy is useful for relapsed peripheral T cell lymphoma cases that tolerated standard chemotherapy. An allogenic hematopoietic stem cell transplantation or new molecular target therapy might be finally selected for refractory peripheral T cell lymphoma. However, an allogenic transplantation has some severe complications. Furthermore we could not easily try phase I or II new molecular target drug treatment. We think that PEGS therapy is a useful treatment for refractory peripheral T cell lymphoma before allogenic transplantation or new molecular target drug treatment.
