A variety of tumors arising in the neck often provides a difficulty in the diagnosis. Here we present a retrospective clinicopathological study of 108 tumors on the neck except those due to thyroid or parathyroid diseases, in which histological diagnosis could be achieved by biopsy or surgery during a past 12-year period. An analysis of the causes revealed that tumors were as predominant as 73.1% (79 cases) followed by inflammation (15.7%) and congenital diseases (9.3%); and malignant diseases accounted for 15.7%. As to the locations, median cervical cyst was predominant on the anterior region of neck; tumor of salivary gland, on the bilateral regions of neck; and atheroma, lymphoma, and calcified epitherioma, on the posterior region of neck. There were 25 tumors of salivary gland including 20 tumors of parotid gland, 12 pleomorphic adenomas, 3 Warthin tumors, one lypoma, and 2 squamous cell carcinomas. Five tumors of submandibular gland were all pleomorphic adenomas. Neurinomas arised in the hypoglossal nerve in 2 and phrenic nerve in one cases. Thirty-three cases of lymphonodus diseases were comprised of 39.4% of simple lymphadenitis, 24.2% of metastasized cancer, 18.2% of malignant lymphoma and the like, 9.1% of nodular lymphadenitis, and the others. Congenital diseases included median cervical cyst in 6 cases, cyst on lateral region of neck in 3, cystic lymphangioma in one.
