Abstract

We report a patient with a rare case of radiation-induced lichen planus (LP) confined to the irradiated breast area following radiotherapy for breast cancer. The clinicopathological features and temporal association supported the diagnosis of radiation-induced LP, with complete resolution following corticosteroid treatment. Our patient’s case indicates that radiation-induced LP is a distinct immune-mediated dermatosis and suggests that ionizing radiation may not only cause direct tissue damage but also influence local immune regulation, potentially predisposing a patient to cutaneous autoimmunity.
