## Abstract

Terra firma–forme dermatosis (TFFD) is a benign skin condition characterized by persistent brownish, yellowish, or gray–black patches, primarily affecting children and young adults. Diagnosis is typically clinical but can be enhanced using dermoscopy and ultraviolet-induced fluorescence dermoscopy (UVFD). This case report presents three patients diagnosed with TFFD, highlighting the unique UVFD patterns observed and the effective management strategies employed. The findings underscore the importance of recognizing TFFD to alleviate patient concerns and prevent unnecessary interventions.
