A retrospective morphological study was conducted on 1677 lymph nodes which were removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic carcinoma, chronic gastric ulcer, and superficial lymph nodes nuder the diagnosis of reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years from 1980 to 1984. The hematoxylin and eosin stained sections were examined to evaluate for any vascular changes. In selected cases further levels were prepared from the paraffin blocks for Gomori's reticulin stain. The vascular abnormalities were divided into 3 groups, such as hemangiomatoid, pan-nodal vasodilatation and miscellaneous types. The miscellaneous type included the proliferation of smooth muscle which encircled numerous small hilar arteries and veins. The results obtained were as follows: 1) The hemangiomatoid lesions were localized lesions which appeared to be associated with local malignancy, but infrequent in incidence. 2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to affect many nodes in a single group and is relatively associated with chronic gastric ulcer. 3) Miscellaneous lesion was nonspecific and appeared both local malignancy and chronic inflammation. 4) All three vascular reactions were somewhat more frequent in female than male.

Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

This study is performed to evaluate usefulness of dermal measurement of benzidine and benzidine based dye as one of the occupational exposure assessment method for these compounds. We selected one benzidine manufacturing factory and one dye manufacturing factory in Incheon area. Eleven workers were for benzidine manufacturing factory and twenty four for dye. We analyzed relationships among air level, amount on skin and concentration of urinary metabolites for these compounds. Airborne levels of benzidine and dye were measured by NIOSH 5509, 5013 methods. Amount of these compounds on skin was measured with skin wipe method. Concentration of benzidine metabolites in urine was measured by High Performance Liquid Chromatography after alkaline hydrolysis. The amount of benzidine on hand skin was 25.05( - 233.2) ng/ur, and the amount of the neck was 2.01 ( - 11.9) ng/cm2 in the benzidine dihydrochloride manufacturing factory. The amount of benzidine on hand and neck skin has positive correlation with concentration of urinary monoacetyl benzidine (r=0.644, p < 0.05) . The amount of benzidine based dye on hand skin was 55.75( - 457.7) ng/cm2, and the amount of the neck skin was 18( - 284.7) ng/cm in benzidine based dye manufacturing factory The amount of dye on hand and neck skin has positive correlation with concentration of urinary benzidine for dye workers (r=0.467, p < 0.05). When assessing the exposure of workers who deal with benzidine, the amount of benzidine on skin should be measured for an accurate exposure assessment.
