Unilateral favre-racouchot disease: evidence for the etiological role of chronic solar damage.

Favre-Racouchot disease commonly presents as comedones, cysts and elastosis in the periocular region of older men. Its etiology has been linked to several exogenous factors. Here we present 2 patients with strictly unilateral manifestation of the disease and a corresponding history of predominantly one-sided chronic occupational sun exposure and smoking, making the case for the causative role of these two factors.
