Terra firma-forme dermatosis (TFFD) is quite unknown condition characterized by dirt-like lesions that are resistant to simple washing. The lesions disappear completely on swabbing with 70% isopropyl or ethyl alcohol, confirming the diagnosis of terra firma-forme dermatosis. The pathogenesis has been attributed to abnormal and delayed keratinization. Most reports have described adolescents or young adults with a history of normal hygiene and intense but unsuccessful attempts at cleansing the affected areas. Herein we described a 7-month-old girl with TFFD.
