Abstract
A 47-year-old man, with complaints of dysphonia and snoring for 10 years, sought medical assistance and underwent physical evaluation and complementary tests that showed a non-infiltrative, well-delimited, approximately 3 cm-large nodular lesion in the supraglottic region, occluding the laryngeal aditus during inspiration. It evolved with need for tracheostomy, followed by lateral pharyngotomy for excision of the lesion. Histologic and immunohistochemical examinations confirmed the rare diagnosis of pleomorphic adenoma of the minor salivary gland located in the larynx. The patient is being followed up with improvement of the symptomatology and absence of lesion recurrence. Pleomorphic adenomas (PA) are heterogeneous benign tumors originating in the salivary gland.
