This report deals with a 71-year-old female patient who developed cancer in her right breast 20 years ago, underwent breast-conserving surgery and received normofractionated radiotherapy with a 60Co unit. 19 years later, fibroids and calcified tissue appeared in her right mammary fold. Furthermore, a deep ulceration developed in this region during chemotherapy of bronchial carcinoma. Apart from being a Type 2 diabetic with arterial hypertension, she was also a habitual smoker. After extensive wound debridement and vacuum-assisted sealing therapy, the affected ribs were dissected and a latissimus dorsi flap was implanted. Our focus here is on the interaction of contributing risks for the development of late radiation sequelae, such as physical (especially unintended hot spots during 60Co irradiation) and pathophysiological factors (comorbidities and morbid affections). Fortunately, side-effects such as these are rare nowadays. As this case shows, however, they can be effectively handled by employing modern plastic surgery techniques.
