The affected cells are T-cells so it is a T-cell lymphoma that have pathological quantities of mucopolysaccharides. Sezary disease is sometimes considered a late stage of mycosis fungoides with lymphadenopathy. There are currently no known causes of Sezary disease.Sezary syndrome and mycosis fungoides are T-cell lymphomas whose primary manifestation is in the skin. The diseases origin is a peripheral CD4 T-lymphocyte, although rarer CD8CD4- cases have been observed. Epidermotropism by neoplastic CD4 lymphocytes with the formation of Pautriers microabscesses is the hallmark sign of the disease. The dominant symptoms of the disease are: Generalized Lymphadenopathy Atypical T-cells Sezary cells in the peripheral blood Hepatosplenomegaly
