The model of lymphocyte differentiation described for Lukes-Collins' classification of non-Hodgkin's lymphoma is related particularly to morphological alterations of nuclei of follicular center lymphocytes by antigenic stimulation. The authors carried out ultrastructural and morphometric studies to investigate morphological alterations during lymphocyte transformation on the nuclear profiles of follicular center, parafollicular and mantle zone lymphocytes in ten tonsillectomy cases of chronic hypertrophic tonsillitis. The nuclear parameters measured included nuclear area, contour index, frequency invagination and cleft, depth of invagination and nuclear diameters. Follicular centers contained a mixed population of lymphocytes consisting of untransformed (type 1), partially transformed (type 2) and fully transformed (type 3) lymphocytes. During lymphocyte transformation in both follicular, and parafollicular and mantle zones, the nuclei had a gradual and progressive increase in size. The nuclear contour index of type 2 nuclei of both follicular and parafollicular and mantle zones tended to be higher than those of type 1 and 3, indicating a greater degree of irregularity and variability of nuclear profiles. Invaginated and cleaved lymphocytes were not confined to me transformed lymphocytes. A considerable portion of lymphocytes had invaginations and clefts in parafollicular and mantle zone as well as follicular center. No difference on the depth of invagination was noted in type 1, type 2 and type 3 lymphocytes. The results indicate that some promise of the Lukes-Collins conepts of follicular center cells and the process of lymphocyte transformation in follicular centers may be necessary to revise

We presented a case of perifolliculitis capitis abscedens et suffodiens associated with acne conglobata in 40-year-old rnale. He had a sausage-shaped plaque containing many fistular tracts on right temnporal area and cicatrizing alopecia on occiput. On the middle portion of upper back he had a adult fist-sized plaque containing many fistular tracts. Histopathologically epidermis showed mild byperkeratosis and keratotic plugging and in the dermis most hair follicles were destroyed and replacel by fibrous tissue but there were moderxte cellular infiltration composed of neutrophils, lymphocytes a.nd hist.iocytes around the remained hair follicles. On serum electrophoresis alpha,-globulin was elevated and gamna globulin was the upper liviit of nornal variation. Skin tests with murnps vaccine, dinitrochloro benzene (DNCB) and old tuberculin disclosed the evidence of de reased c "ll-mediated immunity(CMI). All th se findings suggest thzt immune rriechanisni r,-ay be concerned ivith the pathogenesis in this case. He wa.s treated with th internal administration of antibiotic and corticosteroid and with surgical opening and curettage of fistular tracts

Coronary artery calcification(CAC) is found frequently in the atheromatous plaques CAC is known to have increased frequency above 40 years. CAC without evidence of atherosclerosis in young adults is quite rare, however, CAC combined with aneurysms in young adults have been infrequently reported in patients with a past history of a Kawasaki disease in child. We report an autopsy case showing CAC and aneurysm in the absence of macroscopically identified atherosclerotic lesions in a healthy 23-year-old man. The autopsy examination revealed aneurysmal dilatation of the right coronary artery which was connected with calcified lesion. A calcified lesion of the left anterior descending coronary artery was aslo noted. Microscopically, aneurysmal wall was non-specific except for hyalinized wall and foci of calcification. A striking histologic finding of calcified mass was ring calcification along the wall of the coronary artery. Antecedent Kawasaki disease in the past was suggestive as other reports.

Aortic dissection may be considered the result of a discrepancy between the strength of the aortic wall and the intramural pressure. And factors that predispose to aortic dissection may include systemic hypertension, cystic medial necrosis, Marfan's syndrome, atherosclerosis, disease of aortic valve, pregnancy, giant cell arteritis, hyperthyrosis, disease of aortic valve, pregnancy, giant cell arteritis, hyperthyroidism, and blunt chest trauma. A few of aortic dissection may extend retrograde toward the aortic valve and involve the coronary arteries. Coronary artery occlusions due to mural dissection are an uncommon but well documented cause of myocardial infarction. Although rare, extramural hematoma compressing the coronary artery is another cause of myocardial infarction. At autopsy of 43 years old male who had no critical external wound, pericardial sac was distended and contained 400ml of dark red and clotted blood. Examination of the aorta revealed only minute atherosclerosis, intact aortic valve, and patent coronary ostia. 0.5cm sized aortic rupture was noted at the 3.5cm distal to the aortic valve. DeBakey type II aortic dissection was found to involve the ascending aorta and brachiocephalic trunk. Three intimal tears were 1.5cm, 8cm. 11.5cm distal to the aortic valve and two false lumens which had intact area between them extended 3.5cm distal to the third intimal tear and proximally in a retrograde fashion to the aortic root. Microscopically, sections of aorta showed relatively intact arrangement of smooth muscle and elastic fibers, except mild vascular ectasia and scattered several foci of the small sized aggregation of foamy histiocytes, and there was no evidence of cystic medial degeneration in aorta. Sections of both coronary arteries did not show mural dissection or atherosclerosis. Sections of right atrium and sinus node showed inflammatory reaction, extensive replacement of myocardium by active fibrous tissue consistent with infarction. There was no histologic evidence of myocardial infarction in the walls of other chambers or septum of the heart. We believe that extramural compression of the artery to sinus m\node by the dissecting hematoma was the cause of myocardial infarction involving the right atrium and the sinus node.

Rheumatoid arthritis is considered to be a collagen disease which mainly involves articular structures, sometimes has extraarticular manifestations. It is generally accepted now that periarticular osteoporosis develops in early phase of rheumatoid arthritis and generalized osteoporosis in late period. Of several methods of non-invasive measurement of bone mass, single photon absorptiometry was introduced by Cameron and Sorenson(1963) and it has been used for measuring bone mass by many authors with its precision, reproducibility and objective quantification. We tried to observe the quantitative changes of bone mass in rheumatoid arthritis patients with single photon absorptiometry technique. Through the study of bone densitometry in 30 rheumatoid arthritic women compared with age-matched 60 healthy controls, we obtained follow results. 1. Bone mineral density of the rheumatoid arthritis group was lower than that of the control group, but had no significant statistical difference. 2. Bone mineral density of the 40–49-year-old group and 50–59-year-old group was considerablely different in the rheumatoid arthritis group and control group. 3. Bone mineral density of the group whose rheumatoid arthritis history was over 2 year was lower than that of the group below 2 year.
