Treatment of refractory diffuse large B-cell lymphoma by chidamide combined with autologous stem cell transplantation: a case report.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin's lymphoma, with certain DLBCLs affecting specific anatomic sites, such as primary cutaneous DLBCL, leg type and intravascular large B-cell lymphoma. However, the occurrence of secondary cutaneous involvement in DLBCL while patients are undergoing regular chemotherapy is rare. In this study, we reported a case of refractory diffuse large B-cell lymphoma with cutaneous involvement that achieved complete remission for more than 4 years with epigenetic regulation of chidamide in combination with chemotherapy and autologous hematopoietic stem cell transplantation including a pretreatment regimen containing chidamide.
