Abstract
Background:
Bullous pemphigoid (BP) is the most common autoimmune bullous disease, which is usually seen in older ages. Rarely, radiotherapy (RT) has been reported as a localised trigger factor for BP.
Case:
We present a case of a 64-year-old woman who underwent radical mastectomy and radiation therapy for breast cancer. Two months after the completion of RT with adjuvant Trastuzumab, a BP eruption developed in the irradiated area, spreading thereafter to other skin areas. The patient was treated with oral corticosteroids and the lesions evolved favourably.
Conclusion:
This case demonstrates a relatively benign skin reaction that could develop during the course of cancer treatment, which required co-management by oncologists, pathologists and dermatologists.
