title: The Sézary syndrome. A case with fetal-type glycogen and lymphocytic lymphoma.
abstract: A patient had Sézary syndrome and lymphocytic lymphoma. Cytoplasmic inclusions within the Sézary cells were demonstrated by histochemistry and electron microscopy to be composed of fetal-type glycogen. Results of tests for the presence of virus were negative. It is suggested that the Sézary cell represents a reversion of metabolic systems to more youthful types. Previously reported differences in diastase reactivity of the PAS-positive cytoplasmic inclusions are probably based on whether the glycogen is in fetal or mature configuration.
