Sarcoidosis.

Abstract

Sarcoidosis is a systemic noncaseating granulomatous disorder of unknown origin. The cutaneous manifestations of sarcoidosis often enable the dermatologist to be the first physician to make the diagnosis. This article reviews essential sarcoidosis pathophysiology, clinical polymorphisms, systemic evaluation, and treatment modalities for cutaneous sarcoidosis to further enhance the dermatologist's understanding of this disease entity. At the conclusion of this learning activity, participants should be familiar with the theories of the pathogenesis of sarcoidosis, its cutaneous manifestations, its various syndromes and associations, and its presentation in children. Participants should also be more knowledgeable about diagnostic evaluation, measurement of disease progression, treatment modalities, and the prognosis and mortality data of sarcoidosis.
