Lymphoma and Leukemia in Pregnancy

You are seeing a patient referred by her primary care provider for consultation at your tertiary center’s high-risk obstetrics unit. She is a 27-year-old primigravida at 16⁺³ weeks’ gestation with intermittent swelling of her arms and face that appears within several minutes of brushing her hair and resolves upon lowering her arms. First-trimester dating sonography was concordant with menstrual dates, and fetal morphology appeared normal, with a low risk of aneuploidy; apart from HIV-negative status, results of other routine baseline prenatal investigations are not yet available to you. She has not experienced abdominal cramps or vaginal bleeding. Her medications include only routine prenatal vitamins.
