TLDR Orange spots in scalp trichoscopy can help diagnose scalp sarcoidosis.

The study reviewed clinical, dermoscopic, and histopathological features of two Caucasian female patients with scalp sarcoidosis, aged 22 and 60. Both presented with different types of alopecia and lesions. Dermoscopy revealed decreased hair density and distinctive orange spots, which were suggested as diagnostic clues for scalp sarcoidosis. The presence of dystrophic hairs was noted as a potential indicator of granulomatous activity. This research highlighted the importance of trichoscopy in diagnosing scalp sarcoidosis, a rare manifestation of the systemic disease.
