High-dose-rate endobronchial brachytherapy in endobronchial metastatic malignant chondroid syringoma.

A 65-year-old man with malignant chondroid syringoma (MCS) was found to have pulmonary metastases in the form of multiple pulmonary nodules 4 years after wide excision and adjuvant radiotherapy of a primary abdominal wall tumor. Atelectasis of the lingula due to obstructive endobronchial metastasis, resistant to combination chemotherapy, led us to perform high-dose rate (HDR) endobronchial brachytherapy for the first time in this rare tumor with a favorable response. This case emphasizes the role of HDR brachytherapy as a palliative procedure in endobronchial tumors not responding to other treatment modalities, even those considered to be radioresistant.
