003 Atypical bullous pemphigoid due to radiation therapy

Abstract

Introduction: Both breast cancer and radiation therapy (RT) have been associated with an increased risk of bullous pemphigoid (BP). In the setting of RT, the majority of patients develop BP following completion of treatment, with a mean time to onset of 15.8 months1. Case Report: A 68-year-old Black female with a history of ductal carcinoma of the right breast status post partial mastectomy with sentinel lymph node biopsy and RT was referred to Oncodermatology over two years after completing oncologic treatment for painful erosive blisters that developed in the right inframammary fold with extension to the left breast.
