Atrophie blanche lesions closely resembling malignant atrophic papulosis (Degos' disease) in systemic lupus erythematosus.

Two patients with systemic lupus erythematosus are described who in the course of their disease developed small atrophie blanche lesions that closely resembled those found in malignant atrophic papulosis. Preliminary investigation of these two cases indicates that considerable similarities probably exist in the pathogenesis of malignant atrophic papulosis and the atropie blanche lesions of systemic lupus erythematosus. It is concluded that a diagnosis of malignant atrophic papulosis should only be made after systemic lupus erythematosus has been excluded by full investigation.
