Abstract

Sarcoidosis is a multisystemic granulomatous disease of unknown causes, and cutaneous sarcoidosis (CS) is an early manifestation of the disease. Dermoscopy has gained increasing interest in the past few years as an aid in the clinical diagnosis of inflammatory and infectious skin manifestations. We present a case report about a single, erythematous, and asymptomatic plaque on the face with unexpected dermoscopy characteristics of CS. Learning points: CS on the face of a therapy-resistant actinic keratosis should be considered a differential diagnosis.Dermoscopy can change the diagnosis and lead to the correct management.
