title: Unusual cutaneous manifestations of sarcoidosis.
abstract: The diagnosis of sarcoidosis is best established when there is evidence of granulomatous involvement in two or more organs. Three patients with unusual cutaneous manifestations of sarcoidosis, including palmar and follicular lesions, nonscarring alopecia, and widespread plaque or erythrodermic sarcoidosis, are reported. In all three patients the skin biopsy was important in establishing the diagnosis.
