AbstractAbstract PDF
To fine out the changes of DNA ploidy and cellular proliferation activity during carcinogenesis and evaluate correlation between flow cytometrically determined S-phase fraction and proportion of proliferation cell nuclear antigen(PCNA, PC10) immunoreactive cells, the authors studied on malignant fibrous histocytoma induced by intra-articular injection of 9, 10-dimethy1-1, 2-benzanthracene(DMBA) in the rats. Forty Wistar rats were used. The results obtained were as follows. 1) Firstly, tumors were palpated 5 weeks after the last injection of DMBA and formed in 27 rats at sacrificed. Histologically, these lesions showed storiform, indicative of malignant fibrous histiocytoma. 2) Three cases of DNA aneuploidy were observed at 4 and 5 months after the last injection of DBMA and one of them, which was DNA diploidy at main mass, was found at daughter mass. 3) Flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells in malignant fibrous histiocytoma induced by DMBA were much higher than in control groups and slightly increased according to sequential changes after formation of mass. The comparison of flow cytometrically determined S-phase fraction and proportion of PCNA(PC10) immunoreactive cells showed significant correlation(r=0.6092, p<0.001). Above results strongly suggest that ploidy pattern may evolve into aneuploid type during the development of tumor and proliferation activity increases during the carcinogenesis.

AbstractAbstract PDF
The c-erbB-2 oncogene, which is a new human proto-oncogene similar to EGFR structurally, generates a glycoprotein of tyrosine kinase family with a molecular weight of 185,000 To evaluate the prognostic significance of c-erbB-2 oncogene expression in colorectal carcinoma, We analysed 73 colorectal carcinomas in paraffin sections immunohistochemically, using the monoclonal antibody specific for the c-erbB-2 oncogene product and correlated with clinicopathological data. The results were as follows 1) The immunoreactivity for c-erbB-2 oncogene was localized to cell membrane of the tumor cells and occasionally observed within the cytoplasm. 2) The positivity of c-erbB-2 oncogene expression was 71.2%(52/73) of the colorectal carcinomas overall. According to the histological types, the positivity of c-erbB-2 oncogene in adenocarcinoma(77.4%) was higher than that in mucinous carcinoma(36.4%)(p<0.05). 3) Expression of c-erbB-2 oncogene was significantly correlated with lymph node metastasis or distant metastasis(p=0.0117), Dukes stage(p=0.0432), and TNM classification(p=0.0102). These results suggest that c-erbB-2 oncogene expression may be used as a prognostic factor of colorectal carcinoma because of its correlation with other clinicopathological prognostic factors.

AbstractAbstract PDF
This study was designed to answer the question; (1) How does the DNA ploidy pattern change in hepatocarcinogenesis? (2) How does the nuclear morphology change in hepatocarcinogenesis? Diethylnitrosamine(DEN) (16.5 mg per kg) was subcutaneously injected to female Sprague-Dawley rats(150~200g) by weekly interval for 30 weeks. DNA ploidy and parameters of nuclear morphology were measured by image analyser(IBAS 200, Kontron, FRG). The DNA ploidy pattern was divided into three basic patterns(diploid, polyploid, and aneuploid modes). In 8 cases of saline-injected control rats, the DNA histograms showed all polyploid pattern. Inhepatocyte nodules(hyperplastic nodules), DNA diploidy was the most frequent pattern, being followed by polyploid and aneuploid DNA patterns, contrast to hepatocelular carcinomas in which polyploid DNA pattern was most frequently noted being followed by diploid and aneuploid DNA pattern. Although the nuclei of hepatocytes in hepatocyte nodules and hepatocellular carcinomas were larger and more pleomorphic than those of normal hepatocytes, they were as same as those of normal hepatocytes in regard to nuclear hyperchromasia. DNA content, which was increased in hepatocarcinogenesis, was significantly related to the nuclear area.

AbstractAbstract PDF
Body stalk anomaly represents an extreme maldevelopment of embryonic body folding and is characterized by absence of the umbilicus and umbilical cord. The failure of complete obliteration of the extraembryonic coelom is responsible for the absence of the umbilical cord formation and the wide-based insertio of the amnioperitoneal membrane onto the placental chorionic plate. We have analyzed 10 autopsy cases of various midline anomalies of the body that could best be classified into body stalk anomaly. All cases were either stillborns or dead immediately after birth. The pregnancy was interrupted due to this anomaly in 6 cases, and their gestational ages varied from 17 weeks to 37 weeks. The affected fetuses were characterized bt absent or vestigial umbilical cord, and ruptured amnion with direct amnioperitoneal connection without the mediation of the umbilical cord. Exomphalos with abdominal wall defect and serve scoliosis were characteristic components of this anomaly, that provided important clues in differentiating other similar anomalies. Other associated anomalies included neural tube defect, intestinal atresia, genitourinary and skeletal defects, pulmonary hypoplasia, single umbilical artery and narrow-spaced chest and abdomen, etc. These findings strongly suggest that anomaly of body stalk represents mechanical teratogenesis due to early amnion repture and subsequent effect, and should be categorized into amniotic band disruption syndrome.

AbstractAbstract PDF
To obtain a useful method for the identification of mycobacteria in tissue section, we evaluated 118 cases of tuberculosis: 48 pulm onary, 14 lymph nodal and 56 synovial tuberculosis. Seventy nine of these cases underwent the culture study. Sections stained with anti-Mycobacterium bovis were compared with the results of the Zieh1-Neelsen stain and culture. The immunohistochemical stain for Mycobacterium bovis in al examined cases was not any more sensitive than the Zieh1-Neelsen stain(p>0.05). Neverthless, the immunohistochemical stain was a useful method for the localization of mycobacteria because of the striking contrast between its background and the wider dimension of a positive area. Immunoreactive areas demonstrated a few intact mycobacteria showing a positive reaction in the Zieh1-Neelsen stain. In conclusion, double staining method using the immunohischemical stain for Mycobacterium bovis and the Zieh1-Neelsen stain is an efficient technique in oder to confirm the diagnosis of tuberculosis.

AbstractAbstract PDF
The post-mortem investigation (PI) system in a jurisdiction varies greatly with its lagal and social system and culture. Korean PI system considred as "judical autopsy prime" is not well astablished. To develop our own system, it is neccessary to overview the forensic autopsis performed in Korea. Three hundred forty two forensic autopsies were performed prospectively, every 7 to 15 days among the cases of National Institute of Scientific Investigation (NSI), Ministry of Internal Affairs, during the period from October, 1987 to March, 1989. Cases were those registered to NISI on the author's duty day, not selected or rejected. For each case, autopsy protocols, autopsy reports and police's investigation reports were reviewed. The postmortem hours prior to autopsy were about 60 hours in average, mainly due to the defective PI system. The commonest cause of death(COD) among the natural deaths was the circulatory diseases, followed by diseases f the digestive system. As to the manners of death(MOD), the proportion of the natural deaths was now, comparing to those reported in America and Japan, partly because of our PI system where the public prosecutors determine whether autopsy is necessary on the particular area or not. For the proper application of medical knowledge to the practice of law, the independent institute and qualified specialist for the forensic medicine are mandatory.

AbstractAbstract PDF
Dedifferentiated chordoma is a rare pathologic entity presenting an additional sarcomatous component in otherwise classical chordoma. It has been also emphasized that this neoplasm is classified as a distinct entity because of its different clinical settings and aggressive behavior. Dedifferentiation is a peculiar phenomenon but its histogenesis has remained controversial. A 50-yera-old man developed a huge tumor mass in the retrorectal, presacral area, featured with two histological components. The one was a typical chordoma accounted for approximately 60% of the mass and the other was made up of highly cellular, plemorphic, undifferentiated tumor cells, reminiscent partly to the cells of plemorphic malignant fibrous histiocytoma. Ultrastructural features and immunoreactivity against cytokeratin, S-100 protein and alpha-1-antichymotrypsin in both portions support that histologically different components of this neoplasm derive from the same origin. To our knowledge, this is the first case of dedifferentiated chordoma in Korea.

AbstractAbstract PDF
Gastric lesion in familial polyposis coli is commonly presented with fundic gland hyperplastic polyps, but duodenal and gastric adenomas together with their carcinomatous transformation have been rarely described in familial polyposis coli mostly by case reports. We present three cases of gastric adenomas in familial polyposis coli with one in synchronous development of gastric adenocarcinoma in Korea. All three cases had the family history related to familial polyosis coli and received proctocolectomy because of synchronous development of colonic adenocarcinoma. One patient developed gastric polyposis and adenocarcinoma 8 years after colectomy, and the remaining two presented with multiple polyps either in the stomach or duodenum synchronously at the time of the diagnosis of familial polyposis coli with colonic adenocarcinoma. None disclosed any evidence of Gardner's syndrome. We conclude that association of gastric adenomas in familial oplyposis coli is not uncommon and gastric adenoma-carcinoma sequence is an another important participating mechanism to understand the histogenesis of gastric carcinoma in Korea.

AbstractAbstract PDF
We report a case of angiosarcoma of the jejunum in a 65-year-old female. This angiosarcoma developed 20 years after postoperative irradiation for cervical carcinoma of the uterus. Grossly, the resected jejunum showed a 8 cm long segmental hemorrhagic lesion with multiple, small hemorrhagic nodules or cysts on its serosa and mesentery. Microscopically, the wall of jejunum was infiltrated by epithelioid or polygonal tumor cells arranged in solid nests or lining irregular vascular spaces. The case is of interest that the tumor occurred in the very unusal site for angiosarcoma and the patient had a past history of irradiation for uterine cervical carcinoma 20 years ago. In addition, the resected intestine showed histologic changes of chronic irradiation effect. Therefore, this case supports the view that there is cause and effect relationship between irradiation adn angiosarcoma.

AbstractAbstract PDF
In contrast to the nodular renal blastema which is defined by nests of primitive metanephric cells after 36 weeks of gestation, the nephroblastomatosis is characterized by neoplastic proliferation of the primitive cells. This lesion is presumed to be closely related to the development of Wilms' tumor. We report a case of bilateral nephroblastomatosis associated with Wilms' tumor in a child. This 4 1/2 year-old girl was admitted because of a 10 cm-sized round mass in the right kidney, and smaller nodules in the left kidney and the lung. After three cycles of chemotherapy and subsequent disappearance of the nodules in the left kidney and lung, she underwent a right nephrectomy and a wedge resection of the left kidney. A round Wilms' tumor mass was seen in the lower pole of the right kidney. Remaining right renal cortex showed multiple, slightly depressed gray-white nodules associated with multiple samll cysts. They were comprised of multifocal subcapsular nests of primitive nephrogenic cells with focal tubular or glomerular differentiation. They resembled fetal renal tissue. In the left kidney, similar nests of primitive cells were also noted. These lesions were interpreted as multifocal perilobar type of nephroblastomatosis.

AbstractAbstract PDF
Compared with osteosarcoma of bone, primary osteosarcoma of the soft tissue is very rare. Extraskeletal osteosarcoma is also a highly malignant pleomorphic sarcoma composed of cells exhibiting primarily osteoblastic, and to a lesser extent, chondroblastic differentiation. A case of extraskeletal osteosarcoma in the right sole is presented in a 67 year old male. The patient had noticed a progressively enlarging soft tissue mass, during about 14 months. This sarcoma was located in the soft tissues without attachment to the skeleton, as determined by examination of the X-Ray findings. The mass of right plantar portion was simply excised and pathologically confirmed to be an extraskeletal osteosarcoma. The clinical and pathological features of this sarcoma are described, and brief review of the literature is made.

AbstractAbstract PDF
Hamartoma of the bladder is quite a rare entity which is composed of a disorderly admixture of mature cellular elements normally present in the urinary bladder. There is a great controversy regarding the pathogenesis of this lesion. Whether it is a true hamartomatous lesion or metaplastic lesion developed secondary to the inflammatory process. Similar or identical lesions has often been given by other names such as florid examples of cystitis glandularis. We prefer to cell florid examples of cystitis glandularis rather than hamartoma when it was occurred in an old age higher then 50th decade. Here we report a case of hamartoma of the urinary bladder in 44 years old man. Cystoscopic examination revealed a papillary polypoid mass which was attached to the fundus of bladder by long stalk. The mass measured 1.5 cm in greatest diameter. It was composed of epithelial nests resembling von Brunn's nest, cystitis glandularis or cystitis cystica dispersed in a stroma rich in smooth muscle and fibrous tissue.

AbstractAbstract PDF
The Pleomorphic xanthoastrocytoma(PXA) is considered as a special subgroup of gliomas because of its distinctive characteristics: onset in young subject; predilection for the temopral or parietal lobe and a superficial location; frequent appearance as a yellow encapsulated mass with a grossly visible tumor-associated cyst; marked histological pleomorphism; little or no mitosis and no necrosis; presence of a rich reticulin network; and demonstrable GFAP in many of the fusiform and giant cells; most importantly, the relatively favorable prognosis despite plemorphism and bizzare giant cells in the microscopic picture. The objective of this report is to add one more case of pleomorphic xanthoastrocytoma to the medical literature.

AbstractAbstract PDF
Microcystic adenxal carcinoma is an unusual, locally aggressive neoplasm that has recently been recongized as a clincopathologic entity. Its histologic appearance includes both pilar and eccrine differentiation. Microscopically, the tumor consisted of small cysts and gland-like structures in superficial portion. In other area, basaloid cell nests and abortive hair follicles in the sclerotic stroma were seen. The cysts were filled with secretory eosinophilic material, which was positively stained with Periodic acid-Schiff and carcinoembryonic antigen. Immuno-peroxidase staining for carcinoembryonic antigen supported the dual differnetiation of this neoplasm. Despite the benign histologic appearance, there was deep and extensive infiltration of the subcutaneous tissue.

AbstractAbstract PDF
Spindle cell carcinoma of the upper aerodigestive tract mucosa was usually presented as polypoid mass and shows squamous cell carcinoma or dysplasia in the surface and underlying spindle cell proliferation. The spindle cell area discloses a variable pattern of sarcoma including rare osteosarcoma of 0~20% incidence. The histogenetic origin of the spindle cell component is now considered a metaplasia of squamous cell carcinoma. We experienced a case of spindle cell carcinoma of larynx showing massive underlying bone formation with proliferation of osteoclast-like cells in 75 year-old man. The immunohistochemical study demonstrates positive reaction with cytokeratin in area of squamous cells and with vimentin in area of spindle cells and osteoclasts. There are very focal reactivity for high molecular weight cytokeratin in spindle cell area.
