A case of gastric duplication associated with marked atypism in an adult is reported. The patient was a 62-year-old woman presenting a mass in left upper quadrant of abdomen. The mass was a closed gastric cyst located in the greater curvature, measuring 11 9 cm in diameter. The cyst had common muscular layer with stomach. It showed gray-white firm cystic wall with yellowish brown soft necrotic tissue. Microscopically, the cyst was lined by columnar mucin-secreting epithelium having marked cellular atypism. The cyst wall was supported by layers of smooth muscle, accompanied with severe fibrosis and chronic inflammation.

A clinical and statistical study was done for 123 patients with histologically proven colorectal malignant tumor from 1983 to 1986 at the department of anatomical pathology. Yeungnam University Hospital. The results were as follows: 1. Ratio between male and female was 1.6:1 and incidence was most prevalent in 7th decades comprising 29.3%. 2. Location of tumor was the most frequent in rectum (65%). 3. Frequent symptoms and signs in case of right colon were pain, abdominal mass and bowel habit change. In left colon, they were pain, bowel habit change and bloody stool or melena. In rectum, they were bloody stool or melena, bowel habit change and pain. 4. Duration of symptom was 1 to 3 months (33.3%). 5. The most frequent histological type was adenocarcinoma (82.9%). 6. According to Duke's classification, 32.9% of the tumor were stage C2. 7. Operative procedures were Mile's operation (47.0%), right hemicolectomy (19.8%), and lower anterior resection (11.7%). 8. Polyps were the most frequent associated disease. 9. The most common complication was wound infection (11.1%).

Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body but occur primarily in the submucosa of the intestine and brpnchi. Carcinoid tumors synthesises numerous bioactive amines such as serotonin, and cause the carcinoid syndrome. Rectal carcinoids present as asymptomatic submucosal nodules less than 2cm in size. In contrast to other carcinoid tumors, distant metastasis are rare(less than 15%). Malignant potential is seen almost exclusively in patients with tumors larger than 2cm. Transanal local excision suffices for tumors less than 2cm, with radical surgery reserved only for larger tumors and those with histological evidence of invasion of the muscularis propria. I have experienced two cases of rectal carcinoid tumors less than 2cm, which do not invade the muscular wall of the rectum. These carcinoids were treated with endoscopic polypectomy.

Necrotizing lymphadenitis was first recognised as a self-limiting lymphadenitis by Japanese workers in 1972. It is a distinct clinicopathologic entity, but can be mistaken as malignant lymphoma. We have studied clinicopathologic features in 15 cases of necrotizing lymphadenitis. This disease occurs predominantly in young adult. Male-female ratio is 2 : 1. The commonest presentation is lateral cervical lymphadenopathy. Pain, tenderness, and fever can be seen. Biopsy of the lymph nodes from all patients demonstrates the characteristic histologic features : multifocal, relatively circumscribed nodules in the cortex and/or paracortex, consisting of a mixture of activated large lymphoid cells, histiocytes and Small lymphocytes. Numerous karyorrhetic debris are present. Neutrophils and plasma cells are strikingly absent.

For the more practical and convenient application of the Tzanck test, we evaluated several staining methods and cytological findings 98 cases of vesicobullous skin diseases. Fixation by air-drying of specimen aad modified Giemsa staining method were thought to be the most appropriate procedure in clinical use. The disease studied were chickenpox, herpes zoster & simplex, contact dermatitis, Id reaction, tinea pedis, urticaria pigmentosa, incontinentia pigmenti, farnilial benign pemphigus, hand-foot-mouth disease, erytherna multiforme, toxic epiderrzal necrolysis, fixed drug eruption, and septic vesicle. Among these, herpes and chickenpox vesicles shawed the most characteristic and specific findings. And degenerating giant cell could be added as an useful diagnostic marker for these diseases in relatively old lesions. In the other diseases, cytological findings were neither charcteristic nor specific. But these findings suggested the possibility of picking up useful findings by more elaborated study including more large number of cases.

Utrasonic evaluation has been suggested as a screening method for early ovarian cancer. This study was designed to evaluate the aceuracy of pelvic ultraesound to measure the ovarian volume as the preliminary study. The ovarian volume me ured. by ultrasound was compared with findings at. surgery. Subjects far this investigation were 25 menstruating patients and 12 climacteric patients who were scheduled for gynecologic surgery chiefly unrelated to adnexal masses. The mean nf ovarian volume with menstruating patients was 5.7+/-5.9cm3 and that of climacteric patients was 2.5+/-l.3cm3(P<0.01). The eorrelation coefficient between the ovarian volurne measurement made by two examiners was 0.80. The correlation coeffieient between the ovarian volume measured by transvaginai ultrasonography and ovarian volume at laparotomy was 0. 37 and poor, The ll ovaries(52%) among the 24 ovaries of 12 climacteric tients were not visualized. So, this study suggested that the ovarian volume measurements af the postmenopauml by transvaginal ultrasonograpy was not simple and demanded the skill and laboraus training.

The clinical and pathological features of a case Malignant mixed mullerian tumor of the ovary in 45 year-old female patient with a brief review of the literature are presented. She had both ovarian tumors. The masses are multilocular cystic tumor with interspersed solid component. The cystic component is filled with serous fluid. Microscopically the tumor is composed of epithelial element & intimately related mesenchymal element. The epithelial element shows the findings of adenocarcinoma of solid, glandular and papillary growth. The mesenchymal element is composed of malignant-looking stroma with cartilage formation.

Medroxyprogesterone acetate(MPA) is one of the most commonly used hormonal agents for the treatment of advanced or recurrent endometrial adenocarcinoma. However, the progesterone receptor content of endometrial carcinoma varies directly to the degree of differentiation and inversely with stage of the tumor. Thus one would predict that MPA therapy would be less effective in advanced and poorly differentiated tumors. In addition, MPA has been shown to reduce progesterone receptor content of both normal and malignant endometrial cells, which could result in loss of hormone responsiveness. Tamoxifen, which is often used in breast cancer therapy, has also been used in the treatment of patients with advanced and recurrent endometrial carcinoma. Tamoxifen is known to have some estrogenic effects at low concentration and one of these effects is induction of progesterone receptor both in normal and malignant endometrium. This property has focused interest on sequential or simultaneous use of tamoxifen and MPA in the therapy of endometrial carcinoma. The growth inhibitory effects of MPA and tamoxifen were tested on six longestablished endometrial carinoma cell line(HEC-1-A, HEC-1-B, RL 95-2, AN3CA, KLE) and on SCHE-1, a new endometrial carcinoma cell line established in our laboratory. MPA and tamoxifen were used in growth experiments either alone, simultaneously or sequentially. The MCF-7 breast cancer cell line was used as a control. Only 20% reduction in cell number was achieved after 10 days of exposure to the drug, even with the highest MPA concentration tested(10micronm) in endometrial carcinoma cell lines. But in MCF-7 cells, 60% reduction in cell number was achieved with the same concentration of MPA(10um). Ten days of feeding with 5micronm tamoxifen produced a 96% reduction in cell number in MCF-7, a 91% reduction in HEC-1-A, a 88% reduction in HEC-1-B, a 98% reduction in AN3CA and a 71% reduction in KLE cultures. In SCHE-1 cultures a 83% reduction in cell growth was seen and no viable cells remainde in RL 95-2 cultures after 10 days of feeding with a 5uM tamoxifen. In AN3CA cultures, simultaneous exposure to 5um tamoxifen and 5um MPA resulted in partial reversal of the tamoxifen-induced growth inhibition. In RL 95-2, HEC-1-A and HEC-1-B cultures, simultaneous use of these drugs had the same effect as tamoxifen alone, whereas in KLE and SCHE-1 cultures a slight additive growth effect was observed. All six endometrial carcinoma cell lines resumed logarithmic growth when medium containing tamoxifen of logarithmic growth under these conditions was slower than that in the other endometrial carcinoma cultures. Our results show that MPA does not have growth inhibitory effects in these endometrial carcinoma cell cultures, whereas tamoxifen has been shown to have potent endometrial carcinoma cells. These findings are of special importance since patients who are most likely to need adjuvant therapy for advanced or recurrent endometrial carcinoma are those with estrogen receptor and progesterone receptor negative tumors.

Background: Reporting rate of notifiable communicable diseases has been assumed to be low in Korea. To encourage timely reporting of notifiable communicable diseases and to improve the reporting process by the Infection Control Unit, a disease code-based electronic surveillance and in-house electronic reporting system was developed and implemented in February 2003. We evaluated the reporting rates of notifiable communicable diseases before and after the implementation of the electronic reporting- system. METHODS: The electronic reporting system, which was integrated to the computerized physician order entry system, was designed to monitor KCD-4 codes at the time of every order entry. Whenever the system recognized the predetermined codes of notifiable communicable diseases, it generated an alert box to recommend reporting: and then a physician could fill up an electronic report form, which was collected and faxed to the local public health authority by the Infection Control Unit. Reporting rate of notifiable communicable diseases in 2002, when the conventional paper-based reporting system was used, was assumed comparing the number of cases reported actually and that of cases identified to be reported by reviewing the medical records and electronic database. RESULTS: From March to July 2003, 181 cases with tuberculosis and 14 with other communicable diseases were reported whereas 106 and 9 cases were reported respectively for the same 5-month period in 2002. Reporting rate using the conventional reporting system in 2002 was assumed to be 61% and 39% respectively. Conclusions: Using a disease code-based electronic reporting system, reporting of notifiable communicable diseases could be improved compared with conventional paper-based reporting system.
