A 30‐year‐old woman presented with a 1‐year history of a pruritic eruption on the extremities, characterized by several annular plaques. The patient had been treated unsuccessfully with medium‐potency topical steroids. The lesions had an erythematous papular border with an atrophic center (width, 1–4 cm) ( Fig. 1). No oral, genital, or nail lesions were observed. 1Annular lesion with an infiltrated border and atrophic center A skin biopsy from one of the plaques was performed. Histopathologic examination of the raised border showed hyperkeratosis of the stratum corneum, focal thickening of the granular layer, basal liquefaction degeneration of the epidermis, and a band‐like subepidermal infiltration with numerous Civatte bodies. In the center of the lesion, the epidermis became thinner ( Fig. 2). Elastic fibers were reduced or absent in the papillary dermis. 2(a) Biopsy of the border of a plaque with the typical changes of lichen planus (hematoxylin and eosin, ×10), with flattened epidermis in the center of the plaque; (b) medium power of the border of the plaque with details of the changes of lichen planus (hematoxylin and eosin, ×40) The patient was treated with high‐potency topical steroids for 2 months with clinical improvement.
