We present the case of a pregnant woman with aplastic anemia. The 22-year-old patient presented with 27 weeks of gestation and lymphoproliferative syndrome at the Instituto Nacional de Perinatología in Mexico City. The bone marrow biopsy confirmed the diagnosis and the immunophenotype was negative for malignancy. The treatment consisted of transfusions and planned birth at 35 weeks. Afterwards, the patient was referred to a bone marrow transplant unit.

Objectives: To describe the perinatal results in a patient with paroxysmal nocturnal hemoglobinuria. Methods: We present the case of a patient diagnosed with paroxysmal nocturnal hemoglobinuria at the Instituto Nacional de Perinatología, Mexico. Case report: The 19-year-old patient presented a 26-week pregnancy and pancytopenia. Infectious, pharmacological and autoimmune etiologies were discarded. Flow cytometry identified paroxysmal nocturnal hemoglobinuria clone type II/III in over 50% of granulocytes and monocytes. During pregnancy, the management consisted in transfusion support and anticoagulation with acenocoumarin. Delivery occurred at 38.5 weeks of gestation. The patient was then referred to a bone marrow transplant unit.
