Dermoscopy in cutaneous sarcoidosis

Cutaneous sarcoidosis has a wide variety of manifestations and can be challenging to diagnose clinically. Dermoscopy is a useful tool to support the clinical diagnosis. Herein, we report an elderly woman with pruritic facial plaques. Dermoscopy showed translucent orange globules with shiny white lines, and microscopic examination showed non-necrotizing granulomas with perigranulomatous fibrosis. Shiny white structures on dermoscopy are conventionally associated with basal cell carcinoma, melanoma, and dermatofibroma, and have not yet been reported in sarcoidosis. Current descriptions of dermoscopy findings of sarcoidosis in the literature are summarized. Further differential diagnostic entities for this presentation are described and treatment options for cutaneous sarcoidosis are discussed.
