The appearance of morphea after radiotherapy, especially in the context of breast cancer, is a rare but known phenomenon. The incidence of post-irradiation morphea (PIM) of the breast is approximately one in every 500 patients, a higher rate than morphea of any other etiology, which is three per 100000 per year. PIM usually appears less than 1 year after irradiation (range 1 month to 32 years). The histological pattern of PIM is different from the one in post-irradiation fibrosis, which is a common side effect of radiotherapy and usually appears during the first 3 months after irradiation. Several theories have been proposed to explain the pathogenesis of PIM, probably caused by a disturbance of the cytokine pattern. The development of PIM in patients with autoimmune diseases has been described in the literature. To our knowledge, we report the first case of PIM in a patient with subacute cutaneous lupus erythematosus. We should therefore pay attention when looking at patients with PIM to search for an underlying autoimmune disease.

We describe a 44-year-old female with triple-negative breast cancer who developed skin erythaema, sclerosis and contracture of her entire right breast 15 months after completion of post-lumpectomy chemotherapy and radiotherapy, consistent with post-irradiation morphoea (PIM). PIM is a rare complication of breast irradiation that impairs a patient's quality of life. PIM is located usually at the radiation port or in the surrounding tissue.
