Terra firma-forme dermatosis (TFFD) is a rare and underdiagnosed condition that clinically presents as asymptomatic dark brown to black colored plaques that resemble dirty skin. Given the unfamiliarity of the disease, TFFD is regarded as a lesser-known phenomenon, despite the existence of a straightforward diagnostic sign. To the best of our knowledge, only a few cases of TFFD have been reported, and in the present case, the occurrence of TFFD at the site of varicella zoster secondary to wolf isotopic phenomenon in a short duration of two months after healing of lesions is the first reported case.
