A “butterfly rash” may be due to a variety of dermatological conditions. (A) The malar rash of ACLE refers to erythema over the nasal bridge and cheeks that spares the nasolabial folds. Erythema of ACLE can be found in other areas of the face, such as the forehead here. (B) Facial erythema in dermatomyositis tends to involve the nasolabial folds. (C) Rosacea can mimic the facial erythema of ACLE but tends to worsen with specific triggers such as alcohol, heat, and spicy foods.
