A Rare Case of Recurrent Cervical Bronchogenic Cystadenocarcinoma Treated with Reconstruction of Tracheal Wall

Abstract

We experienced a case of recurrent cervical bronchogenic cystadenocarcinoma on the inner wall of the trachea. The patient is a seventy-one-year-old woman. After total thyroidectomy and anterior neck dissection were performed, the tumor relapsed on the inner wall of the trachea immediately. The tracheal wall cartilage with recurrent tumor was resected. Pieces of rib cartilage and dental impression materials (plastic silicone) were used to reconstruct the tracheal wall. To acquire sufficient structural strength, an outer frame of the trachea was made with pieces of rib cartilage. A rubber medical glove filled with dental impression materials was placed into the tracheal lumen as an inner stent. Three years after operation, there was no evidence of tumor recurrence, and the tracheal wall was reconstructed and retained adequate strength as a respiratory tract. We concluded that dental impression materials are very useful for reconstructing the inner lumen of the trachea.
