Lichen sclerosus et atrophicus (LS&A) is an uncommon inflammatory dermatosis that leads to chronic scarring and skin atrophy. Lesions may occur anywhere but have a predilection for the anogenital region, trunk, proximal extremities, and sites of trauma. We report a unique case of LS&A that developed on the right inferior breast following postoperative radiotherapy for breast carcinoma.

A 68-year-old white woman was referred for an exquisitely painful area on her right breast. Three years earlier, she had been diagnosed with stage 1A right breast invasive ductal carcinoma, which was successfully treated with lumpectomy and adjuvant docetaxel and cyclophosphamide, radiotherapy, and anastrozole.
