Summary.— During the ultrastructural study of the cutaneous lesions of 5 cases of systemic lupus erythematosus (S.L.E.) and 2 cases of discoid lupus erythematosus (D.L.E.), the authors report the changes observed in dermal elastic fibres. These changes consist in a progressive disappearance of the granular matrix and in the subsequent appearance of the fibrillar component of the elastic fibres. These modifications of which several types are described, end in the formation of fibrillar bodies. The evolution of these changes is compared to the evolution of actinic elastosis.
