Noninvasive Prenatal Testing Leading to a Diagnosis of Hodgkin Lymphoma.

Objectives: Noninvasive prenatal testing (NIPT) is a screening method used to detect the most common fetal aneuploidies using cell-free fetal DNA (cffDNA) obtained from maternal blood. Due to the high sensitivity and specificity, low false positive rate, and use as early as 10-weeks' gestation NIPT has been rapidly integrated into prenatal care. While NIPT is an excellent screening tool, the results can be influenced by many factors including placental mosaicism, maternal aneuploidy or mosaicism, and occult maternal malignancy. The diagnosis and treatment of malignancy during pregnancy present many challenges ranging from the use of imaging techniques to the delivery of optimal therapy, weighing the unique risks to both the mother and the fetus. We present a case of a 30-year-old woman diagnosed with Hodgkin lymphoma after NIPT and outline the challenges in diagnosis and treatment of malignancy occurring during pregnancy.
