This clinical study was based on 491 cases of neck mass during 10 years from January 1974 to December 1983 at the department of general surgery, National Police Hospital. Thyroid lesions and acute inflammations were excluded from this analysis.
1) In the histological analysis of neck tumors, tuberculous lymphadenitis was the most common lesion (39.5%) and nonspecitic lymphadenitis was the next(20.6%).
2) The most common age group in neck tumors was 2nd decade(32.0%) and the next was 3rd decade(19.1%).
3) Nonspecific lymphadenitis was the most common lesion under 10 years age group, tuberculous lymphadenitis between 11 to 40 years and metastatic malignant tumors over 41 years.
4) Of the overall sex distribution, male was 255 patients and female was 236. Congenital lesions showed the sex ratio of male to female, 1 = 1.2; tuberculous lymphadenitis 1 : 1.4; benign neoplasm 1 : 1.1; nonspecific lymphadenitis 1.5 : 1; malignant lymphoma 1.2 : 1 and metastatic malignant tumor 2.2 : 1.
5) In the male, tuberculous lymphadenitis was the most common lesion(32.2%) and nonspecific lymphadenitis was the next(23.5%). In the female tuberculous lymphadenitis was the most common lesion(47.5%) and nonspecific lymphadenitis was the next(17.4%).
6) Of the metastatic tumor of 83 cases, Primary site were known in 26 cases. They were 11 stomach cancers, 8 lung cancers, 4 thyroid cancers, 2 breast cancers and 1 oropharyngeal cancers.
7) Considering the site of lesion, tuberculous lymphadenitis and malignant lymphoma were bilateral in 53.1%, and 54.3%, respectively. The others were unilateral. Metastatic malignant tumor was 5.4% on the left and 38.6% on the Right.
