A 28-year-old woman with sarcoidosis had military, skin-colored papules localized on the upper back. The lesions closely simulated lichen nitidus.

Therefore, the microscopic reaction pattern also resembled those of lichen nitidus. This case is a unique form of micropapular sarcoidosis in respect to the clinical appearance and microscopic changes.
