RESUMO
We report the case of a 22-year-old primigravida detected as having sickle cell disease (SCD), initially presenting in the third trimester (30th week) of pregnancy. The patient came to our center with a complaint of severe lower limb pain. The peripheral smear showed marked anisopoikilocytosis, numerous leptocytes, sickle cells, and target cells. High-performance liquid chromatography corroborated the diagnosis of SCD, showing a significant peak in the sickle window. The patient was conservatively managed and delivered a healthy baby through normal vaginal delivery. Delayed presentation of SCD in the third trimester of pregnancy is unusual. This report aims to bring attention to the possible causes of such a lag in detection. We also suggest measures to refine the antenatal healthcare screening at multiple levels, with regard to the detection of sickle cell hemoglobinopathy.
