Non-Hodgkin's lymphoma (NHL) is infrequently diagnosed during pregnancy. Most NHL's complicating pregnancy are aggressive and disseminated. This presentation together with the possible teratogenecity of diagnostic methods dictate a limited staging workup during pregnancy. Although prognosis had been reported to be poor, there is recent evidence to suggest that when properly treated, pregnancy does not affect the course of lymphoma. The risk to the fetus can also be reduced by an appropriate therapeutic approach.
