Primary retroperitoneal malignant lymphoma is rare, and primary retroperitoneal indolent B-cell lymphoma has not been reported. A 64-year-old woman presented anuria. Imaging techniques showed large retroperitoneal mass, and biopsies from it revealed non-Hodgkin indolent B-cell lymphoma (small lymphocytic lymphoma/chronic lymphocytic lymphoma). The tumor appeared retroperitoneal primary and extr...
متن کاملSmall lymphocytic lymphoma: a clinicopathologic analysis of 268 cases.
We analyzed specimens from 268 patients with small lymphocytic lymphoma (SL) to identify prognostic factors significant for survival. These patients were staged and treated according to the protocols of the Cancer and Leukemia Group B, Eastern Cooperative Oncology Group, Southeastern Cancer Study Group, and the Southwest Oncology Group.
