Segmental tracheal resection (nine rings) and reconstruction for carcinoma showing thymus-like differentiation (CASTLE) of the thyroid.

Abstract

Tumors invading the trachea are rare, and although literature often suggests five tracheal rings as the maximum limit of tracheal resection with primary closure, longer tracheal resections and primary closure are possible in many patients. One such locally invasive tumor with propensity for tracheal invasion is carcinoma showing thymic-like differentiation (CASTLE) of the thyroid.
