Lymphoma with Recurrent Cycles of Spontaneous Remission and Relapse — Possible Role of Apoptosis

Abstract

We describe a patient with a unique mantle-cell lymphoma, with cycles of acute illness alternating with spontaneous remissions. During the acute phase the patient had fever, generalized lymphadenopathy, hepatosplenomegaly, increased liver-enzyme concentrations, leukocytosis, and thrombocytopenia. These bouts remitted after two to three weeks without treatment. Fifteen such cycles were documented over a period of 50 months. During the acute phase blast-like B lymphocytes in the blood expressed surface IgM, IgD, and CD5, whereas during clinical remission a small population of IgM and CD5+ lymphocytes persisted. Two B-cell clones with differently rearranged heavy-chain genes consistently appeared in the blood during the . . .
