Favre–Racouchot syndrome (also known as "Favre–Racouchot disease," and "Nodular cutaneous elastosis with cysts and comedones") is a disorder consisting of multiple open comedones that occurs in skin damaged by sunlight, especially under and lateral of the eyes. The comedones are widened openings for hair follicles and sebaceous glands filled with horny material.
Favre–Racouchot syndrome is named after the French dermatologistMaurice Favre and his pupil Jean Racouchot (1908-1994). It was described in 1932 by Favre and then reviewed in details by Favre and Racouchot in 1951.
Chronic exposure to UV light can result in skin thickening as well as elastic destruction of the skin. At least in one instance, the occupational exposure can sun to UVA light (UVB is blocked by many car windows) resulted in the skin destruction on one side of the face.
