Zosteriform Lichen Planus

Since Devergie in 1854 first described linear lichen planus, numerous cases1have been reported in the literature, but there have been notably few of the more rare zosteriform lichen planus. Hence, a case recently presented before a combined meeting of the Chicago and the Detroit Dermatological Society is considered of sufficient interest to warrant description. There is a definite distinction between the linear and the zosteriform type of lichen planus, to which there has not been strict adherence. In the former condition the papular elements appear as narrow lines not over 1 or 2 cm. wide, which may follow the course of a nerve, of a vein or of a lymphatic vessel or one of Voigt's lines. In the latter the lesions form a band several centimeters wide that follows the course of a peripheral cutaneous nerve and its branches or appears over areas of radicular nerve distribution. REPORT
