Ultrastructural pathology of lymphocytes in neuronal ceroid-lipofuscinoses.
Lymphocytes were studied by electron microscopy in five cases of neuronal ceroid-lipofuscinoses (NCL), one of infantile, three of late infantile and one of juvenile types. Each type of NCL revealed specific cytoplasmic inclusions, namely, granular bodies in the infantile form, curvilinear profiles in the late infantile form and fingerprint profiles within vacuoles in the juvenile type. Survey of the literature also confirmed the high correlation between subtype of NCL and type of lymphocytic inclusion. The electron microscopic examination lymphocytes offers easily available diagnostic informations.
