Airway recanalization of bronchial metastasis and obstruction by smooth muscle tumour of uncertain malignant potential by a silicone OKI-stent™.

There is no standard treatment for smooth muscle tumour of uncertain malignant potential (STUMP) but it usually has a good prognosis. Airway stenting is performed to manage central airway patency. In the present case, it was no treatment for STUMP, but performance status was good, so airway stenting was performed.
