Ribosome lamella complex in neoplastic cells of a Sézary's syndrome.

Abstract
The 1st case of ribosome lamella complex (RLC) is reported in abnormal cells of a Sezary''s syndrome, A T [thymus-derived] cell malignancy. Until now this ultrastructural cytoplasmic inclusion was usually described in hairy cell leukemia and other lymphoproliferative syndromes of B [bone marrow-derived] cell origin. Since RLC are also observed in abnormal lymphoid T cells, in nonlymphoid cells and in nonhematopoietic cells, they lack diagnostic specificity.
