title: Pityriasis lichenoides and idiopathic thrombocytopenic purpura in a young girl.
abstract: Pityriasis lichenoides is an inflammatory skin disorder characterized by erythematous, desquamative papules and plaques. An acute form, pityriasis lichenoides et varioliformis acuta, and a chronic form, pityriasis lichenoides chronica, represent the two ends of the spectrum of this disorder. Most commonly seen in children and young adults, its etiology is unknown. We describe a young patient with concurrent pityriasis lichenoides and idiopathic thrombocytopenia purpura, a previously unreported association.
