摘要
Primary pancreatic lymphoma(PPL)is an extremely rare form of extranodal malignant lymphoma.The most common histological subtype of PPL is diffuse large B cell lymphoma(DLBCL).In rare cases,PPL can also present as follicular lymphoma,small lymphocytic lymphoma,and T cell lymphoma either of non-Hodgkin’s lymphoma or of Hodgkin’s lymphoma.T-cell/histiocyterich large B-cell lymphoma(T/HRBCL)is an uncommon morphologic variant of DLBCL with aggressive clinical course,it is predominantly a nodal disease,but extranodal sites such as bone marrow,liver,and spleen can be involved.Pancreatic involvement of T/HRBCL was not presented before.Herein,we report a 48-year-old male who was hospitalized with complaints of jaundice,dark brown urine,pale stools,and nausea.The radiological evaluation revealed a pancreatic head mass and,following operative biopsy,the tumor was diagnosed as T/HRBCL.The patient achieved remission after six cycles of CHOP chemotherapy.Therefore,T/HRBCL can be treated similarly to the stage-matched DLBCL and both of them get equivalent outcomes after chemotherapy.

Pancreatic involvement of T/HRBCL was not presented before. Herein, we report a 48-year-old male who was hospitalized with complaints of jaundice, dark brown urine, pale stools, and nausea. The radiological evaluation revealed a pancreatic head mass and, following operative biopsy, the tumor was diagnosed as T/HRBCL. The patient achieved remission after six cycles of CHOP chemotherapy. Therefore, T/HRBCL can be treated similarly to the stage-matched DLBCL and both of them get equivalent outcomes after chemotherapy.
