Follicular dendritic cell sarcoma in pregnancy: case report and review of the literature.

Follicular dendritic cell (FDC) sarcoma is a rare tumor. Most cases that have been described involve lymph nodes in young adults, but have not been reported in pregnancy. We describe the case of a 20-year-old woman with a FDC sarcoma diagnosed during pregnancy that initially presented as a painful mass in the right axilla. The patient underwent a tumor excision and chemotherapy. The intrapartum course was uncomplicated and she delivered a live female child at 34 weeks. During her postpartum course, she received radiation therapy and chemotherapy.
