Case of lichen planus with unusual features

A 25-year-old woman came with an itchy red rash on her back since 2 years ago. This lesion then extended to the abdomen, arms and legs. From the patient's back, we found irregular linear hyperpigmented patches with some of the edges in the form of hyperpigmented plaques. On the abdomen, arms and legs, erythema-hyperpigmented plaque and patches were visible along the elevated edges with multiple scattered sizes. Lichen planus (LP) has several types based on various clinical manifestations. The diagnosis of LP can be made based on the clinical appearance and symptoms of pruritus. Many diseases can mimic other diseases so histopathology is used to make the diagnosis. Here, we report a case of LP with unusual features with diagnosis confirmed by histopathological examination. The patient was treated with oral and topical potent corticosteroids with good response. ©
