Newly diagnosed malignancy during pregnancy is rare affecting approximately 1 in 1,000 pregnancies. Breast followed by hematologic malignancies are most common. Hodgkin's lymphoma (HL) is a lymphoid neoplasm which can present with lymphadenopathy or mediastinal mass and represents 6% of all malignancies diagnosed during pregnancy. Treatment involves a combination of chemotherapy with or without adjuvant radiation which poses significant challenges when diagnosed antepartum. We highlight a 28-year-old primigravida at 26 weeks gestation who presented to the emergency department in Japan with cough, dyspnea, and sore throat for 3-5 days. Initial chest radiography demonstrated a large perihilar mass with mediastinal shift. Follow-up CT chest revealed an anterior mediastinal mass measuring 8 cm × 19 cm × 16 cm with features concerning for aggressive lymphoma. The patient was subsequently transferred to a stateside tertiary care center for expedited workup. She underwent two core needle biopsies, both of which were non-diagnostic. Cardiothoracic surgery performed a cervical mediastinoscopy with excision of the enlarged right supraclavicular lymph node. Pathologic analysis revealed classical HL, nodular sclerosis subtype. Treatment was initiated with adriamycin, bleomycin, vinblastine, and dacarbazine with two cycles planned antepartum followed by additional cycles postpartum. The patient had an uncomplicated vaginal delivery at 38 weeks gestation. Diagnosis of HL in pregnancy is rare, and expedited diagnosis can be challenging as multiple diagnostic and treatment modalities may impact pregnancy. Management in pregnancy requires a multidisciplinary approach, and decisions regarding treatment and delivery timing should be weighed against risk to the fetus. [ABSTRACT FROM AUTHOR]
