The Sézary syndrome.

Symptoms of the Sézary syndrome are described in a case history. Sézary's syndrome is a lymphoproliferative process of the skin, which eventually develops into an erythrodermia. Strange lymphocytes with a cerebriform chromatin structure, often with T-cell characteristics, circulate in the blood stream. In few instances they are also found in lymphnodes and bone marrow. This primarily benign disease can become malignant, possibly due to an overaggressive cytostatic therapy. Besides the hitherto unknown endogenous causes, exogenous factors cannot be excluded.
