RESUMEN

Necrotizing sialometaplasia is a benign condition first described in minor salivary glands of the soft palate with morphological changes which can be misinterpreted as squamous-cell carcinoma. Similar lesions have been subsequently reported in other locations including major salivary glands, lip, breast and skin (the term syringometaplasia has been applied for the latter). We report three cases of such a process involving submucosal glands in the trachea following prolonged translaryngeal intubation.
