IntroductionThe incidence of papillary thyroid carcinoma (PTC) has rapidly increased worldwide over the past 15 years. Although most PTCs are non-aggressive, but some patients may have poor outcomes due to extracapsular (EC) extension, lymph node (LN) involvement, and distant metastases (1).The trachea is in close proximity to the thyroid gland and can be affected by thyroid cancer spreading beyond the gland. Tracheal invasion by invasive thyroid cancer is rare. Symptoms of tracheal invasion range from none to fatal, including airway obstruction and bleeding. Hoarseness, hemoptysis, and respiratory distress have been reported in some patients with obvious tracheal invasion. Surgery remains the best management for most patients with PTC. Most surgeons follow a special approach, depending on preoperative diagnostics and intraoperative assessment, by means of shaving, partial resection or transverse circumferential (sleeve) resection of the trachea(2). Here, we report a case of PTC with tracheal invasion in a 69-year-old man with successful seven centimeters of trachea resection followed by anastomosis in intact area of trachea.
