steroid rosacea, acne, and perioral dermatitis, is a well-known side effect of topical corticosteroids
Begin as red-purple macules, papules, or small plaques Rapidly develop a hyperkeratotic surface
Early classic DLE- sharply demarcated, coin-shaped (i.e., discoid) erythematous plaques covered by a prominent, adherent scale+
Typically expand with erythema and hyperpigmentation at the periphery
Leaving hallmark atrophic central scarring/telangiectasia/hypopigmentation
FDE
Fixed drug eruption (FDE) Development of one or more annular or oval erythematous patches
As a result of systemic exposure to a drug
Normally resolve with hyperpigmentation
May recur at the same site with reexposure to the drug+
Repeated exposure to the offending drug may cause new lesions to develop in addition to "lighting up" the older hyperpigmented lesions
