Squamous cell carcinoma of the auricle arising from keloid after radium needle therapy.
The squamous cell carcinoma (SCC) of the auricle was one of the common tumors of not only skin but also ear. SCC of the auricle was described to be the carcinoma of old age with some predisposing factors and keloid was known to be one of the predisposing factors for malignant tumors. Keloid and radium needle therapy were risk factors, latter the major, independently from each other and were reported to conclude in SCC depending on the duration for the keloid and the dose for the radium needle therapy. The increased age with the long duration of these predisposing factors should have to be kept in mind in every situation when these treatment modalities had been planned to. Surgical interventions should always be the first choice in the treatment of not only the carcinomas but also in keloids in selected cases.
