Dermoscopic Aid in the Diagnosis of Cutaneous Sarcoidosis Resembling Dermatofibroma / 대한피부과학회지

ABSTRACT

Sarcoidosis is a multisystem granulomatous disease of unknown cause. The lung is the most commonly affected organ, but the skin is frequently involved. Specific sardoidal lesions are most often found on the head and neck area. The most common specific presentation is multiple papular lesions. The present case shows solitary cutaneous sarcoidosis resembling dermatofibroma, located on the thigh. Dermoscopy can help in the differential diagnosis of cutaneous sarcoidosis. Dermoscopic findings are orange globular-like structures and linear vessels, and areas of scar-like depigmentation. Histopathologic findings show non-caseating granulomas with sparse inflammatory cells. We report a case of cutaneous sarcoidosis resembling dermatofibroma, which was diagnosed using dermoscopy.
