The Successful Treatment of Multiple Cutaneous Malignancies with HPV Vaccination: Case Report
An elderly, immunocompetent patient presented multiple invasive squamous cell carcinomas of the keratoacanthoma subtype superimposed on a psoriatic plaque. After failing initial treatment with oral acitretin, alternative therapies were considered. Due to the patient’s advanced age, location of the tumors and extensive tumor burden, invasive therapy was deemed impractical. After careful consideration, the more novel approach of injecting the 9-valent HPV vaccine was performed. Ten months after the first dose, the patient’s skin displayed neither clinical or histologic evidence of any residual cancer. We believe that this is the second reported case of the 9-valent HPV vaccine successfully treating non-melanoma cutaneous malignancies.
