title: [Cutaneous sarcoidosis].
abstract: The frequency of skin involvement of sarcoidosis is 10-30% of all cases, but the prevalence of a particular type of cutaneous lesion varies among races as well as individual cases. Cutaneous involvement is divided into specific and nonspecific categories. Specific lesions include nodules, plaques, lupus pernio, subcutaneous nodules, and other rare manifestations as well as scar infiltrates. Despite the clinical importance of scar infiltrates in the diagnosis of sarcoidosis, it is often overlooked because the lesions are usually small and asymptomatic. There is some clinical importance of cutaneous sarcoidosis; the ease in obtaining lesional samples which enables a histological diagnosis of sarcoidosis, and the association of a particular type of cutaneous lesion with other organ involvement.
