| A rare variant of cutaneous lichen planus with characteristics of both annular and atrophic lichen planus features in the same lesion. Fewer than ten cases have been reported in the literature. Small violaceous papules develop on the trunk and extremities with an atrophic center and a raised hyperpigmented border. Patients are generally middle-aged and have no past history of cutaneous lesions. Histopathologically, the peripheral border has the typical features of lichen planus, while the centre of the lesion shows loss of rete ridges. There is loss of elastic fibers within the papillary dermis, both centrally and peripherally. |
