Saccular mucocele and laryngeal cancer.

Saccular mucoceles are a definite entity and probably occur more frequently than is supposed. Confusion with internal laryngoceles is possibly due to lack of understanding of basic anatomy and physiology. A 49-year-old man had a saccular mucocele that was possibly associated with laryngeal cancer, although a definitive diagnosis was only made two years later. The laryngectomy specimen was serially sectioned and showed an internal laryngocele on the side that was not operated one. This patient remains alive and well four years after excision of a T4 carcinoma, although a unilateral radical neck dissection was performed two years ago.
