Hodgkin's disease in association with Down syndrome: a case report.

The increased incidence of malignancies, especially acute leukemia, in Down syndrome has been clearly established. The association of Hodgkin's disease with Down syndrome has not been extensively documented, and only a few cases have been reported. We present here a case report of Hodgkin's disease in an 11-year-old female child with Down syndrome. The child presented with a stage IVB nodular sclerotic Hodgkin's disease and died of progressive disease. We also present a brief review of the mechanisms of development of malignancy in Down syndrome.
