Abstract
INTRODUCTION: Acute radiodermatitis is a significant complication of cancer radiotherapy, and platelet-based therapies are emerging as potential new treatments. MAIN SYMPTOMS AND IMPORTANT CLINICAL FINDINGS: In this report, we present the case of a patient with head and neck cancer undergoing radiotherapy combined with the monoclonal antibody cetuximab. After 4 weeks of this treatment, the patient developed cutaneous radiation dermatitis. Despite receiving standard treatment with corticosteroids and emollient cream, the lesion did not improve. MAIN DIAGNOSIS: cutaneous radiation dermatitis on head and neck cancer patient. THERAPEUTIC INTERVENTIONS: Topical application of platelet gel was initiated on the wound. From the second week of radiotherapy to the 4th week, homologous platelet-rich plasma was applied on the dermatitis using a bandage, 4 times a day. OUTCOMES: The topical treatment with homologous platelet gel resulted in complete healing of the radiodermatitis, including restoration of the epidermis, reepithelialization, and reduction in associated pain. CONCLUSION: homologous platelet gel might be an alternative to standard treatment of radiation dermatitis.
