Histopathological examination was consistent with tracheal schwannoma. After 4 weeks of laser ablation, he underwent tracheal resection and anastomosis with en- bloc excision of the left thyroid lobe via cervical approach(Figure 3). 5 tracheal rings were excised in the procedure.
RESULTS: Final histopathological examination demonstrated a transmural tracheal mass abutting the left thyroid lobe consistent with tracheal schwannoma. Tracheal resection margins and lymph node were free of tumor. Tracheal tumor was abutting the thyroid lobe but no invasion was seen as thyroid capsule was intact(Figure 4).
