title: [Delayed post-transfusional hemolysis, leukemoid syndrome, autoimmune hemolytic anemia. Coordinating Committee for the Specific Study of Anemias under the chairmanship of H. Rochant].
abstract: We report an observation relating to a history of dissociated pancytopenia with unexpected severe hemolysis following surgery for colonic carcinoma. Following short-term monochemotherapy with 5-fluorouracil investigations revealed neutropenia and leukemoid syndrome. The anemia probably resulted from the interaction of 2 consecutive mechanisms: delayed post-transfusional hemolysis through anamnestic alloimmunization and an autoimmune hemolytic anemia whose biological evidence persisted for several months after the initial episode.
