Development of non-Hodgkin's lymphoma of the colon after radiation therapy for Hodgkin's disease.

Developments in the therapeutic approach to Hodgkin's disease have resulted in excellent long-term survival statistics. However, these patients are at risk for second malignancies, most commonly acute myelogenous leukemia and non-Hodgkin's lymphoma. We present a patient who developed non-Hodgkin's lymphoma of the colon simulating adenocarcinoma 14 years after successful radiation therapy for Hodgkin's disease.
