A comprehensive search strategy was employed across multiple databases, yielding 14 case reports for inclusion. The cases were divided based on CLL diagnosis onset, either before or during pregnancy. Our results showed that patients diagnosed during pregnancy (n = 5) were mostly asymptomatic at diagnosis, with management ranging from supportive care to leukapheresis and transfusions. Postpartum treatment varied, with some patients requiring no additional therapy and others receiving chemotherapy. Pregnancy outcomes were generally favorable, with most neonates born healthy at term. However, one case of Richter transformation resulted in maternal death despite treatment.
