This distinct form of cutaneous sarcoidosis presents as purplish plaques around the nose, ears, lips, face, and fingers (Fig. 13-4). It is usually an insidious process with slow progression that results in scarring, fibrosis, and deformity. It rarely involutes spontaneously and is associated with bony involvement specifically and systemic disease in general.
