Nodular sclerosing Hodgkin's disease with giant Reed-Sternberg cells.

A 70-year-old woman with multiple symptoms and extensive lymphadenopathy had a lymph node biopsy specimen that contained highly pleomorphic, giant Reed-Sternberg cells that resembled cells from other malignant giant cell neoplasms. The cells were strongly positive for Leu-M1, alpha 1-antitrypsin, S-100 protein, kappa light chain, and lambda light chain. With five courses of chemotherapy for pathologic stage IV-B Hodgkin's disease, the patient achieved a complete remission, and remains free of disease 85 months after diagnosis.
