No. Lupus miliaris disseminatus faciei is a chronic granulomatous disorder of the face of unknown cause. Clinically, it presents as multiple brown to brownish-red to brownish-yellow papules of the face (Fig. 13-9), especially the central face and ears. The cause of this mysterious granulomatous disease is unknown, although some dermatologists consider it to be a variant of granulomatous rosacea. Histologically, it is composed of sarcoidal or, more commonly, caseating granulomas that sometimes demonstrate connections to hair follicles.
