Neurogenic tumors are the most common type of mediastinal tumor and constitute the majority of neoplasms of the posterior mediastinum. Schwannomas originating from the intrathoracic vagus nerve are extremely rare. The present study describes the case of a 58-year-old man with a large vagal schwannoma in the left superior mediastinum. A large tumor with a round shape was identified in the left superior mediastinum. The tumor originated from and encased the vagus nerve. Using video-assisted thoracoscopic surgery, the tumor was completely excised with amputation of the vagus nerve encased within in the tumor. One year post-surgery, the patient was free of recurrence with no symptoms other than hoarseness.

Abstract. Angiolipoma is a rare benign tumor that most commonly occurs in the extremities and trunk. Angiolipomas originating in the bronchial tree are extremely rare. To the best of our knowledge, only one such case, confined to the bronchus intermedius, has been reported to date. The present study describes the case of an asymptomatic 74-year-old man with a yellowish round mass incidentally discovered at the orifice of the right lower bronchus during a routine health check. The tumor originated from the membranous part of the right inferior bronchus. Using a high-frequency electric snare and argon plasma coagulation under general anesthesia, successful bronchoscopic resection of the tumor was performed. At 15 months after the surgery, the patient remained recurrence-and symptom-free.
