Lumps of the neck are easily found by patient and physicians due to inspection and palpation. Tuberculosis, nonspecific inflammation and metastatic lesions are commonest.
Abundance of lymph nodes in the neck and centropedal drainage of the body lymphatics into the neck region makes the neck favorite metastatic site of the neoplastic lesions of the facimaxilla,thorax and systemic.
During the past 8 years and 7 months from May 1972 to Dec. 1980, 517 cases of neck mass confirmed by pathological examination.
The results were as follows.
1. Histopathologically congenital lesions were 6.2% inf lammatoty lesions 51.5%, benign tumor 10.2 Yo, primary malignant tumor 8. 1 Yo, metastatic malignant tumor 21. 5% and others 2.3%. Most common lesion is tuberculous lymphadenitis which is 36.8%.
Primary lesions of metastatic malignant tumor show 27% of lung and bronchogenic 12.6/ of stomach, 6.3% of liver
2. Classification of lymphoma shows 71.4% of Non-Hodgkin´s lymphoma, 16.7% of Hodgkin´s disease and 11. 9% of reticulum cell sarcoma. In Non-Hodgkin´s lymphoma, nodular type were 47.6% which most common type is mixed cell type as 26.2 % and dif fuse type is 16.7 Yo.
3. In sex incidence, male was 48.5% and female was 51.5%. In age incidence, 2130 years old age group was 24% which is most common.
Congenital lesion, primary malignant tumor and metastatic tumor show higher inc idence in male than female as 2.2 : 1, 3. 8 : 1 and 1. 7 : 1, respectively.
Inflammatory lesion shows higher incidence in female especially on tuberculous lymphadenitis.
4. Regarding the site of, lesion, right side was 34.4% of total case left side was 36. 6 %, bilateral was 10. 6 %, anterior portion was 3. 1 %, posterior portion was 3. 2 Nineteen percent of lymphoma was developed bilaterally. Metastatic carcinoma was developed at supraclavicular area, 79.3%.
5. Forty-five percent of total case developed within I year.
6. The tumor size measures up to I Cmw as 25.7%, within 1-3Cm was 38.3f/o.
7. Most common symptom and sign was palpable mass in 60%. In metastatic carcinoma, respiratory and G-I symptom were 430/6. In tuberculous lymphadenitis, fever and chill with respiratory symptoms were 27.8% and the positive lesion in chest X-ray was 29.6% of 71 checked case, and 63.4% was normal findings.
