Lymphomatoid contact dermatitis.
Five elderly patients with recurrent and progressive erythematous patchy dermatitis had temporary flares of generalized erythema and associated positive patch tests. The histopathologic findings were of a distinct pattern of lymphocytic dermal reticulosis and chronic epithelial response. We believe this represents a potential pre-Sézary state that can be recognized by the course and the histologic pattern.
