Terra Firma‐forme Dermatosis in a 4‐Month‐Old Girl

  Terra firma‐forme dermatosis (TFFD) is an idiopathic condition characterized by asymptomatic, dirtlike, thinly papillomatous, hyperpigmented plaques which cannot be removed with routine cleansing, but clear with firm wiping with 70% isopropyl or ethyl alcohol. Commonly involved sites include the neck, trunk, and umbilicus. Most reports have described adolescents or young adults with a history of normal hygiene and vigorous but unsuccessful attempts at cleansing the affected areas. We describe a 4‐month‐old girl with TFFD, who is the youngest patient thus far reported with this condition.
