[Peculiarities of lymphocytes during dermatosis. Ultrastructural study of 100 cases].
Peripheral blood lymphocytes from one hundred patients with skin disorders have been examined under the electron microscope. The bloods of 20 donors were used as controls. One observed: Branched Tubular Structures (so-called Lupus type inclusions) in 8 cases (4 systemic Lupus Erythematosus out of 15; I mixed connective tissue disorder; 3 cutaneous lymphomas). As regards Lupus, these findings are in agreement with those already reported in the literature. However, the presence of such inclusions in Lymphomas calls attention once again on the fact that the lymphocyte appears like a possible common denominator to both autoimmune diseases and lymphomas; Intented or cerebriform nuclei in 12 cases, all lymphomas, including 8 cases of Sezary Syndrome out of 8 and 4 Mycosis Fungoïdes out of 12; Lamellar type inclusions, similar to those described by Hovig, in 13 cases (connective tissue disease 1, lymphomas 2, psoriasis 4, miscellaneous 4, healthy controls 2). Their meaning is unclear; they may be artifacts.
