Pleomorphic adenoma - the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine.

Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma. The study confirmed the parotid gland as the most common location of tumor mixtus. In some cases, the large size of the tumor and its location were the cause of life-threatening complications.
