Terra firma-forme dermatosis may mimic a variety of hyper pigmented dermatoses. The diagnosis can be characterized using dermoscopy and confirmed with the SMART (Skin Modified by Alcohol Rubbing Test) evaluation. When terra firma-forme dermatosis (Duncan's dirty dermatosis) is clinically suspected, clearance of the dermatosis follows rubbing the affected skin with 70% isopropyl alcohol.
