Adenoma pleomórfico gigante en paladar. Reporte de caso y revisión de la literatura

Pleomorphic adenoma is considered the most frequent benign tumor found in the salivary glands. Histologically it is characterized by presenting epithelial as well as mesenchymal elements. The present study targets the report of a clinical case of a large size pleomorphic adenoma found in a 45 year old patient. The patient was treated at the Oral and Maxillofacial Surgery Unit of the Eastern General Hospital «Dr. Domingo Luciani». The patient reported onset of the disease approximately 17 years before, with a progressive volume increase in the palate. A surgical Brown type II B maxillectomy was planned, with placement of a shutter plate. At a 10 month post-surgery control, tissue formation was observed in the region of the surgical bed, this formation exhibited similar appearance to the surrounding mucosa, with no signs of recurrence and presence of an oral-nasal fistula measuring approximately 2 cm in diameter. Presently, the patient is programmed to receive a fistula closure procedure by means of local flaps as well as subsequent prosthetic rehabilitation.
