Gamma heavy chain disease (gHCD) is a rare B-cell lymphoproliferative disorder that mostly occurs after childbearing age. Here we report the first case of gHCD in a pregnant patient that was diagnosed in the second trimester, and another pregnancy in the same patient after initial treatment for gHCD. The former pregnancy ended in intrauterine fetal death, believed to be caused by insufficient maternal blood flow due to multiple placental infarcts. The latter pregnancy course was uneventful. Although we cannot rule out the possibility that the poor outcome of the former pregnancy was due to an unfortunate complication independent of gHCD, the courses of these pregnancies suggest that non-lymphomatous gamma heavy chain may have a significant impact on pregnancy and that its removal by treatment may improve outcomes.
