Terra firma-forme dermatosis: Two cases

Abstract

Terra firma-forme dermatosis is a dermatosis with unknown etiology which causes dirt-like colour changes on the skin. It is frequently seen in children and adolescents. Its clinical emergence is in the form of gray-brown, mildly papillomatous, pigmented plaques especially on the face, neck, trunk and ankles. Lesions can’t be cleaned by water and soap; they can only be cleaned by rubbing with isopropyl alcohol or ethyl alcohol. In this study, two cases with terra firma-forme dermatosis were defined and the subject was reviewed in the light of literature. [Med-Science 2019; 8(1.000): 237-8]
