Abstract
The authors report a very rare case of pleomorphic adenoma in the epiglottis. A 46-year-old man complained of “unclear voice”. Initially he was diagnosed with an epiglottic cyst after laryngoscopy, lateral X-P, and CT. We performed a puncture of the tumor through a laryngoscope, and determined that this disease was not a cyst, but a tumor. Biopsy and tracheotomy was performed. Pathological diagnosis of the tumor was Pleomorphic adenoma. After 10 days, tumor resection was performed by pharyngotomia mediana suprahyoidea under general anesthesia.
For the diagnosis of pleomorphic adenoma in the larynx, biopsy is essential. It might be necessary to perform the biopsy several times because pathological diagnosis of pleomorphic adenoma in the larynx is not easy.
To treat pleomorphic adenoma of the larynx, surgical resection is primarily recommended. Determination of the method of the surgical approach depends on the tumor size. When the tumor is smaller than 2cm, surgery with a laryngoscope is recommended. However for larger tumors, a skin incision should be made.
