View detailsPharyngeal tumor
Pharyngeal tumors are clinically classified into benign and malignant tumors. Benign tumors include papillomas, hemangiomas, nasopharyngeal fibromas, and pleomorphic adenomas. In addition, schwannomas, neurofibromas, lymphangiomas, lipomas, and chondromas may also occur, but these are all relatively rare. Among malignant pharyngeal tumors, nasopharyngeal carcinoma is the most common, while tonsil cancer, malignant lymphoma, and rhabdomyosarcoma are less common. Leiomyosarcoma and malignant melanoma are rare.
