The study reviewed clinical, dermoscopic, and histopathological features of scalp sarcoidosis in two Caucasian female patients, aged 22 and 60, who presented with folliculitis-like lesions and patchy alopecia. Dermoscopy revealed decreased hair density and distinctive orange discoloration patterns, with perifollicular and follicular yellowish to pale orange spots in one case and diffuse orange discoloration with telangiectasia in the other. These orange spots observed during trichoscopy were suggested as a diagnostic clue for scalp sarcoidosis, while the presence of dystrophic hairs indicated granulomatous activity.
