There are many kind of diagnostic entities in submandibular or neck masses, and we can set up treatment plan and estimate treatment result, prognosis by accurate diagnosis. By reasoning medical and dental history, physical examination, anatomical consideration of masses in submandibular or neck area, location of masses, laboratory and radiographic studies, we can formulate a clinical diagnosis or differential diagnosis. Although a clinical diagnosis might suffice in some instances, a definitive(microscopic) diagnosis is frequently required for proper treatment. In order to get some information about making accurate diagnosis and setting up appropriate treatment plan, we did clinical study and histopathologic classification of 82 patients who visited and were operated for sudmandibular masses at Department of Oral and Maxillofacial Surgery in Seoul National University Hospital from 1988 to 1992. The result were as follows: 1. Submandibular masses occured most frequently in forties and fifties, and there was no sex predilection. 2. Chief complaints were in order of mass, swelling, pain and consistency were sofe mass, mobile hard mass, firm mass, diffuse swelling in descending order. 3. Most frequent pathologic finding was lymphadenitis. 4. Site of submandibular masses were submandible, neck, submental, retromandible in descending order, and there was no predilection between left and right side. 5. Accuracy rate between clinical impression and result was 51.2%.

Colon cancer is the second most common malignancy in Korea. It is classified as superficial type, the mass type, the ulcerative type, the ulceroinfiltrative type, the diffuse infiltrative type and the unclassified type according to the colonoscopic findings. We report here on a case of colon cancer that was initially misdiagnosed as acute infectious colitis at the initial presentation. A 64-year-old man visited to Yeungnam University Hospital for watery diarrhea and lower abdominal pain. Colonoscopy revealed long segmental edematous mucosa and hyperemic mucosa with stenosis in the transverse colon. He was diagnosed as having acute infectious colitis according to the colonoscopic finding. However, two days later after colonoscopy, he visited the emergency room for hematochezia. We performed computerized tomography (CT) and obtained blood samples to find the origin of the bleeding. We found thickening of the transverse colon lumen and ascites on the CT finding and an elevated level of tumor markers; we also obtained the results of the colonoscopic biopsy that was done via colonoscopy. He was finally diagnosed as having colon cancer with carcinomatosis, a poorly differentiated adenocarcinoma.

A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It is a persistent remnant of a vessel that is present as a counterpart of normal right-sided superior vena cava(SVC) in early embryological development but normally disappears later. Its diagnosis can be confirmed by many noninvasive and invasive tests, or it is incidentally diagnosed at insertion into the left subclavian or jugular vein or thoracic surgery. If it is not associated with other congenital cardiac anomalies, it is usually asymptomatic and hemodynamically insignificant. We describe the chest radiograph and CT findings of bilateral SVC with drainage to left superior intercostal vein, hemiazygos, azygos vein and right SVC, and no connection of coronary sinus.

Oriental herbal medicines were examined for mutagenicity in the reverse mutation test on Salmonella typimurium TA98/00 and chromosomal aberration test on cultured mammalina cells (Chinese hamster cell lines). The reverse mutation test was performed by a plate incorporation method with or without a metabolic activation system (S9 mix). Antaeeum, Aurantii Fructus and Kyoaekungkuetang significantly increased revertivle colonies on Salmonella typimurium TA 98 under the condition without S9 mix. Bojungikkitang significantly increased revertible colonies on Salmonella typimurium TA 100 under the condition with S9 mix than under the condition without S9 mix. The other tested herbal medicines did not significantly increased revertible colonies on any of the test strains under the condition with or without S9 mix. In the chromosomal aberration test. most tested herbal medicines did not significantly increased the number of aberrant cells under the conditions with S9 mix at concentrations of 1mg/ml, compared with the vehicle control. However, Gelatinum, Artemisiae Asiaticae Herba and Antaegumchultang, Kungsosan slightly increased revertivle colonies on any of the test strains under the conditions with S9 mix than under condition without S9 mix. These results indicate that most herbal medicines might be carefully used in obstetrics and gynecology, although they do not have the potent mutagenic potential under the present test conditions.
