Pregnancy luteoma is composed of a single or multiple nodules of large lutenized cells that develop during pregnancy but involute during the puerperium. This lesion is usually an incidental finding at the time of cesarean section or postpartum tubal ligation. Microscopically, this tumor is difficult to be differentiated from various types of sex-cord stromal tumors including Leydig cell tumor, luteinized thecoma, adult or juvenile granulosa cell tumors with luteinization, and lipoid cell tumor. We report a case of pregnancy luteoma in a 34-year-old primipara without virilizing symptoms at the time of cesarean section in the right ovary. The mass measured 5x4.5x3.5 cm and 60 gm in weight. The cut surface was homogeneously yellow-orange with mulitple hemorrhagic spots. Microscopically, the tumor revealed solid, trabecular, or microcystic pattern of large granular eosinophilic luteinized cells and somewhat large nuclei with prominent nucleoli. Differentiation from Leydig cell tumor and juvenile granulosa cell tumor was difficult in this case.

In autopsy, the evaluation of the size and weight of th internal organs is very important for the understanding of the pathologic conditions. The normal data of the internal organs must have regard to size, weight, sex, age and body weight. There are many reports on the normal value of human organs in Japan and other Western countries. But there are some variations in normal value according to race, geographics and living standard. In Korea, Lee & Roh had reported on weights of various organs of Korean and their proportional weights to body weights in 1957, based upon autopsy records from 1929 to 1941. But, there has been many improvement in socioeconomic status during past half-century in this country. And the Korean body conditions have much improved. Upon the base of above consideration, normal data fit for present Korean is mandatory. We have analysed records of 45 cases of Korean young adults's autopsy cases which were performed from Jan. 1984 to Dec. 1985, and obtained following data. The results obtained are as follows: Heart : left ventricle thickness; 1.76+/-0.3 cm right ventricle thickness; 0.5+/-0.1 cm Aorta circumference; 6.1+/-0.5 cm Pulmonary a. circumference; 7.0+/-0.7 cm Weight : 338+/-54 gm Lung : size: left; length 23.3+/-2.78 cm, width 12.3+/-2.28 cm, thickness 6.4+/-1.55 cm right; length 24.1+/-2.65 cm, width 14.7+/-2.95 cm, thickness 6.6+/-1.31 cm Weight : left; 541+/-117 gm, right; 634+/-118 gm Liver : size: greatest transverse measurement; 28.5+/-2.7 cm vertical measurement; 16.6+/-1.74 cm great anterior-posterior diameter; 8.8+/-1.51 cm weight: 1,559+/-267 gm Spleen : length: 12.7+/-2.1 cm, breadth: 8.4+/-1.5 cm, thickness: 3.4+/-1.1 cm, weight: 155+/- 69.3 gm Pancreas : length; 16.7+/-2.8 cm, weight: 111+/-34.5 gm Kidney : size: left; length; 11.2+/-0.7 cm, width; 5.9+/-0.7 cm, thickness; 3.8+/-0.8 cm, thickness; 3.6+/-0.7 cm weight: left; 150+/-25 gm, right; 138+/-29 gm Brain : weight: 1,498+/-132 gm

Pseudomyxoma peritonei often have synchronous appendiceal and ovarian mucinous tumors. There has been considerable debate as to whether the ovarian tumors are secondary to the appendiceal tumor or they are independent primary ovarian tumors. It is important to reveal the primary site for treatment and prognosis of a patient. Five cases of synchronous mucinous tumors of the ovary and appendix were studied. Four cases had pseudomyxoma peritonei and pseudomyxoma ovarii. The ovarian tumors were bilateral in two cases, right in two, and left in one. The ovarian tumors were four mucinous cystadenoma of borderine malignancy and one mucinous cystadenocarcinoma, and the appendiceal tumors consisted of four mucinous tumors of borderline malignancy and one mucinous adenocarcinoma. The histology of the ovarian and appendiceal tumors was similar. Rupture of the tumor was seen in all appendiceal tumors and two ovarian tumors. It has been reported that cytokeratin 7 is a useful marker for distinguishing primary ovarian neoplasms from metastases of intestinal origin. All ovarian and appendiceal tumors showed positive reaction for broad-spectrum cytokeratin, but negative for cytokeratin 7. Based on the clinicopathologic and immunohistochemical features, it should be considered that the appendiceal tumors are primary and ovarian tumors are secondary in the synchronous presentation of the ovarian and appendiceal mucinous tumors.

Giant cell arteritis is a focal granulomatous inflammation of arteries of medium and small size that affects principally the cranial vessels, especially the temporal arteries, in older individuals. It appears to be a localized process; its significance apparantly depends on the organ affected. A 67-year-old man was admitted to hospital because of the left scrotal mass and pain lasting for 1 month. On physical examination, the hard masses were palpated at the superior part of the left epididymis without tenderness. Histologically, the spermatic cord showed granulomatous arteritis involving the small and medium sized arteries with a transmural inflammatory infiltrates centered on the inner media, and composed of lymphocytes, histiocytes, some eosinophils and multinucleated giant cells. The elastic tissue stain revealed the fragmentation of the internal elastic lamina along with numerous epithelioid histiocytes and giant cells.

Infantile myofibromatosis with systemic involvement is a very rare disease and is characterized by numerous nodules composed of spindle cells of a myofibroblastic nature. There are often disseminated throughout the subcutis, muscle, skeleton and viscera. We report an autopsy case of infantile myofibromatosis in a stillborn female fetus of 32 weeks of gestation. The nodules, Imm to 2 cm, were found over the whole body and viscera. The involved viscera were the heart, tongue, esophagus, gastrointestinal tract, portal areas of the liver, spleen anc pancreas. There were also associated malformations, viz., frontal meningoencephalocele, flexion defer-mities, syndactyly, cleft palate, agenesis of corpus callosum, pachygyria, diaphragmatic hemia, renal hypoplasia, etc. Multiple basaloid follicular hamartomas of the skin were noted on the face and extremeties. There are no previous reports in the literature of infantile myofibromatosis in conjunction with the above skin lesion and congenital malformations.

Studies on the correlation between proliferative activity of biopsied specimen and pathologic findings of resected specimen have been carried out to find the prognostic factors. To estimate the proliferative activity, 100 cases of biopsied specimen of gastric adenocarcinoma were tested for the PCNA (proliferating cell nuclear antigen) and the AgNOR (argyrophilic nucleolar organizer region) by the immunohistochemical and histochemical stainings, respectively. The resected tumors classified by histologic type, differentiation, depth of invasion, and nodal metastatic status were followed by cell cycle analysis using flow cytometry. The PCNA LI (labelling index) were higher in well or moderately differentiated tumors (P<0.01) than the poorly differentiated ones and the aneuploid tumors (P<0.05) more than in diploid ones. However, there were no correlations among histologic types, depth of invasion, nodal metastatic status and PCNA LI. The AgNOR counts were higher in advanced tumor than in the EGC (early gastric cancer) (P<0.01). In cases with nodal metastasis, most of them showed the AgNOR counts higher than those without nodal metastasis. There were no correlations between the AgNOR counts and the DNA ploidy, histologic type, or differentiation. High PCNA LI and high AgNOR counts were shown in cases with advanced tumors (P=0.000) and nodal metastasis (P<0.05). No correlation was shown with the histologic type or differentiation. The results show that proliferative activity of the biopsied specimen of gastric adenocarcinoma is correlated with the differentiation and the invasion depth of resected specimen. Especially, better correlation is obtained by analyzing both the PCNA LI and the AgNOR counts than by analyzing each.

The authors experienced a case of pulmonary alveolar proteinosis. A 58-year-old woman presented with 6 months duration of cough sputum and multiple patch mottled densities in both lung fields. Major histologic finding was filling of the alveoli by Periodic-Acid-Schiff-positive proteinaceous material with maintenance of normal alveolar architecture. Osseous metaplasia was seen in the alveolar space, focally. Ultrastructural study revealed numerous lamellar bodies in alveolar spaces. The immunohistochemical study using antibody to surfactant apoprotein revealed positive reaction in proteinaceous material.

Heat shock protein(HSP), first found in the MCF-7 human breast tumor cell line is one of the estrogen-regulated proteins and its synthesis is stimulated by estradiol. In this study, immunohistochemical staining was done for estrogen receptor(ER) and HSP on formalin-fixed, paraffin-embedded tissue sections in twelve normal cyclic and twenty carcinomatous endometria. 1) During the proliferative and early secretary phases, the nuclei of surface and glandular epithelial cells and stromal cells had moderate to strong staining for ER, whereas during the mid and late secretary phases, the glandular epithelial and stromal cells had weak staining for ER. The surface epithelial cells had positive staining of variable intensity. 2) From the early proliferative to mid secretary phases, the glandular and surface epithelial cells showed a positive reaction of variable intensity for HSP. In the late secretary phase, the glandular and surface epithelial cells showed a weak positive or a negative reaction for HSP. During the menstrual cycle, the stromal cells remained negative for HSP. 3) In adenocarcinomas of the endometrium, 8 of 11 (72.7%) well differentiated carcinomas were positive for both ER and HSP, while only 3 of 9(33.3%) moderately and poorly differentiated carcinomas were positive for ER and HSP. In conclusion, ER and estrogen-regulated heat shock protein(HSP) were closely related in normal and carcinomatous endometria and the reactivity was decreased according to poor differentiation.

BACKGROUND AND OBJECTIVES: The heat-shock response modulates contractility of vascular smooth muscles. With complementary deoxyribonucleic acid microarray, we tried to identify the novel genes that are involved in the regulation of vascular contraction after heat shock. MATERIALS AND METHODS: Human radial artery strips were mounted in organ baths, exposed at 42degrees C for 45 minutes, and returned to equilibrate at 37degrees C. This study examined gene expression profile associated with heat-shock response in radial arteries of patients with hyperlipidemia by using a microarray that contained 5763 human cDNA. The results of microarray hybridization experiments from the radial arteries of 4 different subjects were analyzed and classified by the cluster program. RESULTS: Among these differentially-expressed genes, Hsp70, Hsp10, alphaB-crystallin, and Hsp60 were significantly increased by the heat shock response. Of non-HSP genes, 15 genes increased, while 22 genes decreased. Among these 37 genes, alphaB-crystallin (CRYAB) (up 1.92-fold), myosin, light polypeptide kinase transcript variant 8, 6 (up 1.70-fold, up 1.68-fold), catenin (cadherin-associated protein, alpha-like 1) (down-0.57 fold) and tropomyosin 3 (down 0.68-fold) were thought to be related with the contraction. Real-time quantitative polymerase chain reaction showed that Hsp70, Hsp10 and alphaB-crystallin were significantly increased. CONCLUSION: Gene expression profile by heat shock provides information about genes implicated in augmentation of vascular contraction after heat shock.

The present study was carried out to investigate the HHsAg in the normal skin, dis- eased skin and skin specimens of window period of HBsAg positive patients in their serum with normal liver function. This study was done by immunoperoxidase techniques using the monoclonal antibody to hepatitis E3 surface antigen and by electron microscopy. Immunoperoxidase staining was dane on twenty specimeris of normal skin Group .D twenty specimens of diseased skin (15 cases of dermographism, 2 cases of purpura, 1 case of follicuht,is and 1 cases of morbilliform eruption) (Ciroup II ) and three specimens of normal skin af window period (Group III ) of HBsAp positive patients in their serum. Twelve cases of Group I, eleven cases of Group IL (1(J cases of dremographism and 1 rase of purpura) and two cases of Group II were stained positively for HBsAg. Positive sites were keratinocyte of epidermis, sweat gland, blood vessel and hair follicle. Electron microscopy failed to reveal viral particle, The above resuts suggest the possibility of transmission of viral hepatitis B thraugh the skin and skin appendages.
