The publication said the skin damage was "consistent with the Favre-Racouchot syndrome
of photodamaged skin, known as dermatoheliosis."
Comedones, as part of disease, are commonly seen in acne vulgaris, Favre-Racouchot syndrome, and cases of nevus comedonicus [1, 10].

Colloid milia in 3 cases (1.5%); 2 (1%) cases each of Lichen amyloidosis and Lichen sclerosus et atrophicus was seen; 1 (0.5%) each case of Parapsoriasis, Favre-Racouchot Syndrome, Pruritus ani, Pyogenic Granuloma, Lupus Profundus were seen, 2 (1%) cases each of reactive perforating collagenosis and granuloma annulare and 3 (1.5%) cases of polymorphous light eruptions.
One case (0.5%) of Favre-Racouchot syndrome, 2 cases each of Reactive perforating collagenosis and Granuloma annulare, 3 cases of polymorphous light eruption, 1 case each of Pruritus ani, Pyogenic granuloma and Lupus profundus were seen.
Differential diagnosis shall include (1) Favre-Racouchot syndrome
(nodular elastosis with cysts and comedones) that tends to affect bilateral forehead and cheeks due to solar damage; (2) comedonal acne that often affects younger individuals with an increased inflammatory response; (3) nevus acneformis, which is a rare, congenital disorder affecting face, neck and chest with dark keratin plugs.
was initially suspected due to her age, cyst location, and concomitant solar elastosis.
