Microcylinders of endoplasmic reticulum in histiocytes in patients suffering from Degos' syndrome and dermatomyositis.
Rare intracytoplasmic membranous inclusions derived from the endoplasmic reticulum were observed in the histiocytes of one case of Dego' syndrome and one case of dermatomyositis. Cross-section and longitudinal sections made it possible to establish a three-dimensional model in which both microcylinders and layers of rolled-up double membranes appear.
