Hypertrichosis is a disorder characterized by increased terminal hair growth located in non-androgen-dependent areas. It may be congenital or acquired, localized or generalized. Iatrogenic hypertrichosis is a dermatological adverse effect related with various systemic and topical treatments. However, acquired iatrogenic localized hypertrichosis is unusual. The case of a 6-years-old child with a history of atopic dermatitis since she was 1 year old is described. She was treated with topical steroids and emollients. In the last year the child developed well defined areas of excessive terminal hair growth on the trunk. The hair grew over lichenified, erythematous and excoriated areas. Her mother referred that these areas were pruriginous and were treated with topical gentamicin-sulphate and betametasone-17-valerate. The correspondance between excoriated, steroid-treated areas and hypertrichosis led to the diagnosis of acquired localized iatrogenic hypertricosis in an atopic patient.
