Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.

We have experienced a case of Vogt-Koyanagi-Harada Syndrome in 35 years-old male. The Voght-Koyanagi-Harada Syndrome is characterized by severe chronic bilateral Ilveitis associated with alopecia, poliosis, vitiligo and signs of meningeal irritation. In presented case, there was extensive posteriar synechia, numerous mutton fat K.P. in addition to cataract, poliosis, vitiligo, headache and dysacousia. Steroid was administered over period of 6 monthes in gradual decreasing dosage, but there was no appearent effect on the course of the disease.

An isolated granulocytic sarcoma (chloroma) of the left ovary occured in the absence of leukemia in a 12-year-old woman. This lesion is defined as a localized tumor mass composed of immature cells of the granulocytic series. Granulocytic sarcomas can occur at extramedullary sites including ovary but, isolated myelosarcoma in the absence of usual manifestations of AML may be rare and has some difficulties in diagnosis. Contrary to findings in other series, granulocytic sarcoma arising in this nonleukemic patient did not progress to acute leukemia during two years she has been followed.

Despite a recent trend toward increased screening and public awareness for colorectal cancer, 30% of patients present with incurable disease. This study was designed to identify objective criteria that might help surgeons decide which patients with incurable colorectal cancer will benefit from palliative resection. Among 33 patients considered incurable colorectal cancer, twenty one patients underwent palliative resection and twelve patients had bypass surgery. Incidence of postoperative complication after palliative resection was 61.9%(13 cases), and after bypass surgery was 58.3%(7 cases). Among patients treated by palliative resection, one patient required reoperation for postoperative bleeding. The operative mortality after palliative resection was 19%(4 cases), and after bypass surgery was 25%(3 cases). The median survival was 11.4 months for patients treated by palliative resection, and was 9.7 months for patients treated by bypass surgery. These results show that palliative resection can be done safely and effectively in patients with incurable colorectal cancer. We believe this approach improved the quality of the remaining life in these patients.

Glanzmann's thrombasthenia is a rare autosomal recessive hemorrhagic disorder characterized by prolonged bleeding time, ad deficient or absent clot retraction in the presence of normal platelet count. The major underlying abnormality in this disease is grossly defective first-phase aggregation of platelet, which are unresponsive to ADP or other platelet agonists such as epinephrine, collagen, thrombin in any concentration. This disability is caused by a decrease or absence of the platelet membrans glycoprotein IIb-IIIa complex, a member of the integrin family of adhesive receptors involved in cell-cell and cell-matrix fibronectin, and vitronectin On the development of surface labeling technique, a variety of biochemical techniques such as radioimmunoassay, crossed immunoelectrophoresis and SDS-PAGE have been used to study the structure and the function of platelet membrane glycoproteins, and to detect the platelet functional defect. But all of these techniques demand a relatively large amount of homogeneous paletelet population that requires manipulation through isolation and washing procedures before analysis. In order to eliminaste such an intricate procedure, we have applied method for analyzing platelet surface components in whole blood using monoclonal antibody and flow cytometry to recognize the absence of severe reduction of platelet membrane glycoprotien llb-llla complex. Platelet analysis by flow cytometry is a successful alternative rapid diagnostic technique for Glanzmann's thrombasthenia patients as well as well as for carriers of this disease. Fow cytometry technique provides a sensitive tool for investigating platelet functional defects caused by altered expression or deficiency of platelet surface proteins.

The authors report series of 360 cases of transthoracic fine-needle aspiration cytology (TFNA) from Oct. 1982, through Aug. 1986 at the Seoul National University Hospital. A diagnosis of neoplastic lesion was established in 50.3% of the cases. A non-neop- lastic diagnosis was made in 38.5%, nondiagnostic one in 6.5% and inadequate one in 4.7% of the total. Statistical findings on cytological diagnoses were as follows. Specificity was 100%: sensitivity, 92%; predictive value for positive, 1.0: predictive value for negative, 0.9; concordance rate, 84.2%: diagnostic accuracy in non-neoplastic lesion, 65.4%, and typing accuracy in malignant tumor, 0.77.

The management of malignant left colon obstruction remains a difficult problem. Conventional surgical treatment is muti-staged and each stage carries its own morbidity and mortality. The purpose of this study is to identify the feasibility and safety of one stage operation in patients presenting with acute obstruction of the left colon. From January 1991 to June 1996, 29 patients received one stage resection for acutely obstructed carcinoma of the left colon at Soonchunhyang University Chunan Hospital. Subtotal colectomies were performed in 9 patients(31.0%), left hemicolectomies in 6(20.7%), low anterior resection in 6(20.7%), sigmoid colectomy in 4(13.8%), anterior resection in 4 patients(13.8%). Subtotal colectomy was performed in patients with massively distended colon of dubious viability and to contain ischemic lesions at proximal colon. Total operative mortality was 6.9%: 5% in the immediate resection with anastomosis group, 11.1% in subtotal colectomy group. Complications included wound infection(4), fecal incontinence(2), intestinal obstruction(2), anastomotic leakage(1), upper G-I bleeding(1), postoperative bleeding(1), pulmonary complication(1). Our results suggest that resection and primary anastomosis can be performed with acceptable morbidity and mortality in patients with acute malignant obstruction of the left colon.

We performed a retrospective study on evisceration and enucleation operated at Chosun University hospital and Chonnam University hospital during the period of 10 years from January 1982 to December 1991. The total number of cases was 550. The incidence was mow common in male. The male and female ratio was 1.85: 1(Male 64.9%, Female 35.1%). The frequency of enucleation and evisceration was as follows trauma; 281 cases(51.1%), glaucoma; 76 cases(13.8%), corneal ulcer; 69 cases(12.6%), panophthalmitis; 43 cases(7.8%), tumor; 33 cases(6.0%), phthisis bulbi, 26 cases(4.7%), others; 22 cases(4.0%). The most frequent cause of the trauma whitch had been eviscerated or enucleated was traffic accident; 129 cases(45.9%), followed by violence; 73 cases(25.9%), industrial accident, 37 cases(13.2%), toy and pencil; 19 cases(6.8%), sports; 12 cases(4.3%), unknown; 11 cases(3.9%). The age-related incidence was peak in the third decades 86 cases(15.6%), followed by fifth decades 85 cases(15.5%) and fourth and sixth decades 82 cases(14.9%), respectively. The mean annual incidince rate was significantly greater among males than females: 2.33 per 100,000 population and 1.93 per 100,000 population, respectively. The overall mean annual rate was 2.13.
