INTRODUCTION: The most important long-term effect of radiotherapy is induction of secondary cancers. A rare radiation-induced tumor is a squamous cell carcinoma of the external auditory canal. Case reports have been described in Asian patients after radiotherapy for nasopharyngeal cancer.

CASE DESCRIPTION: We describe an unusual case report of a 53-year-old Caucasian man who developed squamous cell carcinomas of the right and left external auditory canal, respectively 29 and 30 years after radiotherapy for a pituitary adenoma.

CONCLUSION: In young patients with benign tumors, we should always evaluate whether the benefits of radiotherapy outweigh the risks and side effects. After radiotherapy, screening programs should be developed since early detection improves salvage treatment of these secondary and often morbid tumors.
