ABSTRACT
Sarcoidosis, a multisystem disease of unknown etiology, remains enigmatic in modern
medicine. Skin involvement happens in < 20% of patients with this disease. Yet, when
it occurs, it can be virtually diagnostic or it can be so baffling and obtuse as to
test the diagnostic skills of virtually any clinical dermatologist. Clinically, sarcoidosis
can mimic many conditions, in a manner similar to syphilis. Therefore, the astute
clinician must always consider cutaneous sarcoidosis in diagnosing both obscure and
``obvious'' diseases, such as folliculitis.
