title: Atypical presentations of terra firma-forme dermatosis.
abstract: Terra firma-forme dermatosis is a benign dermatologic condition that presents as dirt-colored patches and plaques, mainly affecting children and adolescents. It is resistant to conventional washing with soap and water but is easily treated with isopropyl alcohol. Clinical awareness of this condition provides a quick, simple resolution. Here we present two cases involving 14-year-old girls with uncommon presentations of terra firma-forme dermatosis. One case involved an upper extremity and the other presented with a history of knee brace occlusion. After diagnosis, both patients were successfully treated with weekly isopropyl alcohol applications.
