ABSTRACT
Leukaemia in pregnancy is rare and lethal. Its incidence is estimated to be 1 in 75,000 pregnancies. Use of chemotherapeutic agents during pregnancy can give rise to maternal and fetal adversity; resulting in dilemma regarding proper management plan. A 25-year-old pregnant lady was presented at 24 wk of gestational age with cervical and inguinal lymphadenopathy and bicytopenia in complete blood counts. Diagnosis of acute lymphoblastic leukaemia was confirmed by bone marrow biopsy. Treated with appropriate chemotherapeutic regimen with some modification in the standard protocol due to pregnancy and delivered successfully by lower segment caesarean section at 34 wk of gestational age. Diagnosis of acute leukaemia during pregnancy need high index of suspicion and need prompt management with the proper chemotherapeutic regimen. Clinical judgement regarding the risk benefit ratio of using chemotherapeutic drugs ensures better mother and fetal outcome.
