A 45-year-old man presented with dysphagia. Computed tomography and magnetic resonance imaging showed an abnormal shadow in the paraesophageal mediastinum, which a thoracoscopic biopsy revealed to be a desmoid tumor that had infiltrated the surrounding tissues. We attempted esophageal stent placement; however, the esophageal stenosis could not be dilated, and bypass surgery was performed first, with tumor resection postponed, and radiation and hormonal therapy were added. Mediastinum desmoid tumors are rare, with only 22 other cases reported in the English language literature. Herein, we report the details of our patient and provide a review of other cases.
