Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.

Two cases of carcinoid tumor of the uterine cervix were reported with emphasis on the histologic, cytologic, histochemical and electron microscopic appearance of tumor cells. Based on the light microscopic findings, one case was a well differentiated carcinoid with acinus formation, and the other was a poorly differentiated anaplastic type, being composed of small cells similar to those of oat cell carcinoma of the lung. Both tumors demonstrated scattered argyrophilic cells on Grimelius stain, and contained neurosecretory granules on electron microscopy. They were in stages II b and IV, respectively, at the time of presentation. The latter patient was treated with vinblastin, platinol and bleomycin, but died in 9 months after the initial diagnosis. The former was lost to follow-up study. Importance of distinction between this highly malignant tumor and other varieties of cervical cancer was emphasized.

One hundred twelve cases of cervical intraepithelial neoplasia (CIN) were reviewed to detect the condylomatous lesion characterized by koilocytotic cells. Condylomatous lesions were present in 12 cases (30.8%) of 39 cases with mild dysplasia, 3 cases (15.0%) of 20 moderate dysplasia, 2 cases (13.3%) of 15 severe dysplasia and 4 cases (10.5%) of 38 cases with carcinoma in situ. These 21 cases with condylomatous lesions were subjected to the study on demonstration of human papillomavirus (HPV) antigen with peroxidase antiperoxidase reaction and 6 simple condylomatous lesions of the uterine cervix were included for control. Twenty seven cases with simple cervical condyloma and condylomatous lesions associated revealed 22 cases of flat type, 3 cases of exophytic type, 1 spiked type, and 1 inverted type. Cells showing a positive reaction for HPV antigen were identified in 5 cases (55.6%) of 27 cases with condylomatous lesions. HPV antigen positive nuclei were found chiefly in koilocytotic cells. The prevalence of HPV antigen positive cells was well correlated with the extent and intraepithelial level of the koilocytotic changes. The results of this study provide a confirmation of the presence of HPV antigens in CIN, and suggest that the HPV may be an important factor in the etiology of CIN.

Gross deciduosis in pregnancy is rare. A case of disseminated deciduosis peritonei studied by light and transmission electron microscopy is reported. The pathogenesis of deciduosis peritonei and relationship with leiomyomatosis peritonealis disseminata are discussed in view of the present findings and those previously reported.

BACKGROUND/AIMS: There is considerable variance in individual susceptibility to hepato-toxic effects of ethanol as evidenced by the finding that only about 10-20% of alcoholics develop alcoholic liver cirrhosis. The aims of this study were, 1) to get the data on the genetic polymorphisms of three major ethanol-metabolizing enzymes (ADH, CYP2E1, ALDH) in normal Korean adults, and to search for the specific genotypes influencing alcohol drinking behavior by the comparison of allele frequencies between healthy control group and heavy drinker group with or without liver disease, 2) to investigate the influence of the genetic polymorphisms of these enzymes on the susceptibility to alcoholic liver disease by the comparison of allele frequencies between heavy drinker group without liver disease and alcoholic liver cirrhosis group. METHODS: Healthy control group included 53 healthy males in military service without evidence of liver disease or alcoholism. Heavy drinker group without liver cirrhosis included 29 males who had been drinking 80g or more of alcohol daily for more than ten years but did not have any clinical evidence of liver disease. Alcoholic cirrhosis group included 43 male patients who had drunk 80g or more of alcohol daily for more than ten years and had clinical evidences of overt cirrhosis. Subjects with hepatitis B surface antigen or anti-hepatitis C antibody were excluded. Genotypes of the three enzymes were determined by PCR (polymerase chain reaction) and restriction fragment length polymorphism (RFLP) with genomic DNAs extracted from peripheral leukocytes. RESULTS: 1) In healthy Korean males, allele frequency of ADH22, ADH31, CYP2E1 c2 and ALDH22 was 81%, 94%, 30% and 14%, respectively. 2) The absence of ALDH22 or CYP2E1 c2 allele were significant risk factors for being a heavy drinker (odds ratio,' 0.09, 0.42, respectively). 3) Although it was not associated with the polymorphism of each ethanol-metabolizing enzymes, the susceptibility to alcoholic liver cirrhosis was significantly associated with combined genotypes of ADH2(22) & ADH3(1+1)& CYP2E1 B or C. COMCLUSION: Genetic polymorphisms of ethanol-metabolizing enzyrnes are significantly associated with the suseptability to alcoholic liver disease as well as alcohol drinking behavior.

We report a rare case of carcinosarcoma arising in the stomach. The tumor is presented in the posterior wall of the gastric lower body and antrum of a 56-year-old man. Grossly the tumor has polypoid appearance with diffuse surface ulceration and measures 5.5 cm in diameter. The tumor is accompanied with three separate well differentiated early gastric adenocarcinomas (two EGC type IIc & IIa). Microscopically, the tumor consists of moderately well differentiated adenocarcinoma in the periphery, and lobulated sarcomatous areas in the center, which shows chondroid differentiation. Transitional areas between adenocarcinoma and chondrosarcoma are evident. Immunohistochemical studies show positivity for cytokeratin and carcinoembryonic antigen in the epithelial component, and for vimentin and S-100 in the sarcomatous component. The transitional areas are positive in carcinoembryonic antigen, vimentin, S-100, and cytokeratin. The tumor extended to the subserosa and showed metastasis of only adenocarcinomatous component in six out of 47 dissected perigastric lymph nodes.

Intestinal obstruction is the commonest cause for emergency surgical intervention in the newborn. An extremely rare cause of intestinal obstruction in the neonate is a congenital abnormality consisting of segmental absence of intestinal musculature with intact serosa and mucosa. This report represents not only the fourth reported case of this anomaly but also the first case associated with long segment Hirschsprung's disease in English-written literatures.

Lobular carcinoma of the male breast is very rare, because of the absence of lobules in the normal male breast. Herein, a case of lobular carcinoma of the male breast with cellular features of signet ring cells is described. A 57-year-old man presented with a left breast mass. Histologic examination showed classic invasive lobular carcinoma with in situ component. Most infiltrating tumor cells had a prominent signet ring cell appearance. The patient was phenotypically male and had fathered children. There was no history of predisposing factors to breast lesion, such as hormone use or gynecomastia.
