"Spontaneous" complete remissions (SCR) are a rare event in chronic lymphocytic leukemia (CLL). In this article, we report three cases of SCR observed in a series of 285 patients followed at a single institution during the last 15 years. SCR was documented by clinical and hematologic data, including bone marrow biopsy, and immune cell markers. A delay of 0.9-1.6 years between "clinical" and "clonal" remission was observed. A review of other cases of SCR in CLL is also performed.
