Thymomas comprise about 1% of all mediastinal tumours and are rare in children. Typically, these tumours are aggressive, with a poor outcome. The current treatment of invasive thymoma is often multidisciplinary. We report a 16-year-old boy with invasive thymoma who was successfully treated with systemic chemotherapy, surgical resection and irradiation. The patient has been in continuous remission for 6 years without radiographic evidence of tumour recurrence.
We report a case of squamous cell carcinoma of the base of the tongue in a 27 years old patient with Rothmund-Thomson syndrome (RTS). An abnormal DNA repair mechanism in some RTS patients predispose them to malignancy and influence the tolerance to radiotherapy.
