title: Unexpected splenic nodules in leukemic patients.
abstract: We reviewed a series of five splenectomy specimens from patients with various leukemias (three cases of chronic myelocytic leukemia, one case of acute myelocytic leukemia, and one case of hairy cell leukemia). In addition to diffuse red pulp disease, we unexpectedly encountered nodules grossly in each of the specimens. These represented sea blue histiocytosis (one case), focal hairy cell leukemia (one case), localized blast transformation (one case), and concentrated foci of treated leukemia (two cases), with a prominence of immature granulocytic precursors on a background of trilineage hyperplasia. These cases are reported because they are unusual and because they furnish interesting correlates of gross and microscopic anatomy.
