title: In situ benign growth after radical radiation therapy of head and neck cancers--report of eight patients.
abstract: Eight patients who developed benign growth at the primary site after radical radiotherapy of head and neck cancers (two laryngeal cancers, six nasopharyngeal carcinoma, NPC) are reported. Most of the lesions appeared as spheral or nodular growth with few symptoms. All were properly diagnosed and treated, but two of them had been wrongly diagnosed and treated as local malignant recurrence. The authors point out that repeated biopsies, before treatment, are very important for differentiating a malignant recurrence from a benign growth. Conservative treatment can cure these lesions.
