A 40-year-old, gravida 3, para 2 woman was initially referred to our department at 31 weeks' gestation complaining of fever, night sweats, malaise in association with jaundice and pancytopenia. Cesarean section with excisional iliac lymph node biopsy was carried out following a period of expectant management. An 1,840 g healthy male infant with an Apgar score of 9 at 34 weeks of gestation was delivered. Histologic examination of the excised lymph node revealed non-Hodgkin's lymphoma (Histiocyte and T cell predominant B cell lymphoma). The patient was evaluated to have Stage II B disease. A chemotherapy regimen of CHOP/Rituximab was instituted with successful maternal-fetal prognosis.
