Successful Treatment of Two Cases of Squamous Cell Carcinoma on the Ear with Intra-Arterial Administration of Peplomycin through a Superficial Temporal Artery

Abstract

Cutaneous squamous cell carcinoma (SCC) is the second most common non-melanoma skin cancer and tends to develop in sun-exposed cosmetic areas, including the ear. In this report, we describe two cases of SCC on the ear successfully treated with intra-arterial administration of peplomycin through a superficial temporal artery. In addition to this selective chemotherapy, we administered oral tegafur, which achieved complete remission of the tumor. These findings suggest that intra-arterial administration of peplomycin with tegafur is one of the optimal therapies for the treatment of SCC developing on the ear.
