Sebaceous carcinoma is a rare and aggressive malignant tumor deriving from the adnexal epithelium of the sebaceous glands. The case of inoperable preauricular sebaceous carcinoma treated with definitive radiotherapy is first reported herein. Radiotherapy of 60 Gy in 30 fractions was combined with a hydrogen peroxide-soaked gauze bolus aiming at potential radiosensitization. Macroscopic complete remission was achieved eight months after radiotherapy with tolerable adverse effects. Although further clinical studies are needed, radiotherapy with a hydrogen peroxide-soaked gauze bolus can be an effective and tolerable treatment for inoperable patients with extraocular sebaceous carcinoma.
