Terra firma-forme dermatosis

Abstract

Terra firma-forme dermatosis (TFFD) is a recently described cutaneous pigmentation disorder. It is a bizarre, acquired and idiopathic dermatosis and is characterized by brown, dirt-like discoloration that cannot be removed by bathing with water or rubbed off with routine detergent soap, but can be removed by isopropyl alcohol. A 20-year-old male came for treatment of chickenpox. Incidentally we observed multiple hyperpigmented plaques on the trunk and back, which disappeared on rubbing with isopropyl alcohol. He had normal washing habits and lesions disappeared after scrub bath. We propose scrub bath as one of the treatment modality.
