Soft tissue sarcoma as second malignant lesion after therapy for Hodgkin's disease. Report of two cases and review of the literature.

Two cases of soft tissue sarcoma following treatment of nodular sclerosing Hodgkin's disease are described. One patient developed a malignant schwannoma after radiotherapy, the other was diagnosed as having a malignant fibrous histiocytoma after treatment with radiation and chemotherapy. Both secondary malignancies arose within the irradiated field after a latent period ranging from 9.5 years in the first to 21 years in the second case. A review of the pertinent literature is given and previous reports of malignant tumors and leukemias following therapy for Hodgkin's disease are summarized.
