Terra Firma-Forme Dermatosis: A Report of Four Cases and Review of the Literature / 대한피부과학회지

ABSTRACT

Terra firma-forme dermatosis is characterized by asymptomatic dirt-like papules and plaques. It appears as dirt-like lesions, but is known to develop in persons with normal hygiene habits. Terra firma-forme dermatosis is rarely reported and has an unknown etiology. It is hypothesized to occur as a result of abnormal keratinization. Terra firma-forme dermatosis is usually detected in children and young adults. Its characteristic features include disappearance with alcohol swabbing. Thus, wiping with alcohol-soaked cotton is recommended before any other examination in cases where terra firma-forme dermatosis is suspected.
