[Desmoid Tumor Treated by Wide Resection of the Anterior Chest Wall] [Article in Japanese]

Summary

We report the case of a 72-year-old man with a desmoid tumor arising from the anterior chest wall which invaded neighboring organs extensively. The patient complained of dyspnea on exertion and appetite loss and was referred to our hospital. Chest computed tomography revealed an anterior chest wall tumor 12 cm in diameter adjacent to the right lung, diaphragm, and sternum. An ultrasound-guided biopsy was conducted, and the tumor was diagnosed as a desmoid tumor. He underwent right-sided anterior chest wall resection with combined resection of the right lung, diaphragm, and sternum body. The chest wall defect was reconstructed using an expanded polytetrafluorethylene mesh (dualmesh). Although initial active surveillance has recently been recommended for asymptomatic patients with non-progressing desmoid tumors, our patient underwent resection because of his symptoms.
