The case of a child with terra firma-forme dermatosis lesions is reported. This is an idiopathic and uncommon condition characterized by asymptomatic dirt-like lesions, which cannot be removed by routine cleaning. Lesions completely disappear after swabbing with 70% isopropyl alcohol. The condition is more frequent in children and often occurs on the neck, trunk, and ankles.
