Twenty cases of gallbladder cancers were examined using 5 mm stepwise tissue sections. We analyzed the clinicopathologic findings of the early (stage 1, II) and advanced carcinoma (stage III, IV, V) and those of carcinoma with or without metaplasia in the tumor. We also performed CEA and p53 immunohistochemical staining and compared their findings with those of normal mucosa and preneoplastic lesions. The results were as follow: 1) All of the early carcinomas (n=5) were incidentally diagnosed after the resection for the gallstone. They were compared to advanced carcinoma (n=15) in the absence of the lymphatic or angioinvasion, recurrence, metastasis and death. 2) Metaplastic and non-metaplastic carcinoma did not reveal any difference of the clinicopathologic findings except age distribution. 3) CEA and p53 were positive in preneoplastic and malignant lesions. The extent of staining was related to the degree of the atypia. From the above results, an early detection of gallbladder cancer is very important for the prognosis of the patients. Since preoperative diagnosis is difficult, thorough pathologic examination of routinely resected gallbladder is necessary for the early diagnosis. CEA and p53 immunohistochemical staining may be helpful in the differential diagnosis of non-neoplastic and neoplastic lesion of the gallbladder.

OBJECTIVE: Sarcoma of uterus is originated from uterine muscles and/or connective tissues and rare and most lethal of all primary uterine tumors. The purpose of this study was to evaluate the clinical outcome of 12 patients diagnosed primary uterine sarcoma at the Department of Obstetrics and Gynecology in Kyungpook National University Hospital between 1984 and 1998 for 15 years. METHODS: After review of chart in twelve patients, data including clinical and histologic findings, treatment and outcome were analysed. RESULTS: The most common histologic finding was leiomyosarcoma(6cases, 50%) and the age of patients ranged 24 to 69 years and the average age was 43.25 years and two patients were nulliparous. The most common sign was abnormal uterine or vaginal bleeding(48%), and pelvic cavity or vaginal mass(16%), pelvic pain(16%), no symptom(16%), in order of frequency. The distribution by FIGO clinical stage was four cases(33%) for stage I, one case (8%) for stageII, one case(8%) for stage III, six cases (50%) for stage N. The nine cases received hysterectomy with or without BSO. Two cases received myomectomy to preserve fertility. The mean follow-up duration was 39.6 months. CONCLUSION: Uterine sarcoma is an uncommon and aggressive tumors with a poor prognosis. Leiomyosarcoma is the most frequent histologic type(50%). Stage I uterine sarcoma with or without adjuvant chemotherapy has better prognosis than other stages.

The correlation of metaplasia to dysplasia and carcinoma in the gallbladder has attracted the attention of many investigators. We mapped and examined a total of 263 cholecystectomized gallbladders to analyze the mucosal changes in the carcinogenesis of the gallbladder. Stones were present in 59.7%, hyperplasia in 28.5%, metaplasia in 55.5% (gastric 37.6%, intestinal 17.9%), dysplasia in 17.1% (low grade 9.1%, high grade 8%) and carcinoma in 7.6%. Metaplasia was more frequently identified in the stone-positive group (62.4%) than in the stone-negative group (45.3%) (P<0.05). Especially, the incidence of intestinal metaplasia was significantly higher in the stone-positive group. Dysplasia and carcinoma were more frequent in the metaplasia-positive group (dysplasia 26.7%, carcinoma 11%) than in the metaplasia-negative group (dysplasia 5.1%, carcinoma 3.4%) (P<0.05). Their incidences were significantly higher in the intestinal metaplasia than in the gastric metaplasia. Forty four percent of the dysplasia-positive cases were associated with carcinoma in the adjacent mucosa but carcinoma was absent in the dysplasia-negative cases. Hyperplasia did not reveal any significant correlation with metaplasia, dysplasia and carcinoma. These results suggest that gallstone is causally related to the metaplasia in the gallbladder and the metaplasia-dysplasia- carcinoma sequence exists in the gallbladder.

A case of Toxic epidermal necrolysis in 19 th years old man is presented. This patient has been suffering from erythematous patches and bullae over entire body including vesicles, erosions, and fissures on both lips since 2 days ago after taking some drugs (analgetics, aspirin, chloramphenicol, sulfisoxazole, erythromycine.) for treatment of tonsillitis. Furthermore, it is very difficult for us to say why the disease has occured. Toxic Epidermal Necrolysis (TEN) by talking drugs or Staphylococcal Scalded Skin Syndrpme (4S) by staphylococcus aurues because staphylococcus aureus was found on bacteriai culture from his throat swab. He was treated with corticosteroid, antibiotics and fluids for 20 days with good result. Literature was briefly reviewed.

Malignant mixed mullerian tumor (MMMT) is an unusual tumor composed of malignant epithelial and nonepithelial components in the same lesion and is subdivided into homologous and heterologous types. Epidemiologically, these tumors are associated with prior pelvic irradiation, functioning ovarian lesions, exogenous estrogen therapy and rarely endometriosis. We experienced a case of uterine MMMT which arose from adenomyosis in a 47-year-old woman who had no specific past medical history. The posterior uterine corpus showed a 3.5x3.0x2.0 cm sized, relatively well defined tumor mass within the background of the adenomyosis. The tumor was composed of well differentiated endometrial adenocarcinoma and sarcomatous stroma with foci of rhabdomyosarcomatous differentiation confirmed by immunohistochemical and electron microscopic studies. Through the immunohistochemical study, both the epithelial and nonepithelial components were positive for cytokeratin and it suggested that the sarcomatous area originated from metaplasia of the adenocarcinoma component. From the overall findings, it is regarded as an uterine heterologous MMMT which arose from adenomyosis.

Obstructive colitis is an ulceroinflammatory lesion of the large intestine at a distance proximal to the obstructing or potentially obstructing lesion of any etiology. It has been suggested that a rise in the intraluminal pressure related to the obstruction results in a fall in the intramural blood flow with subsequent ischemic necrosis. We examined 7 cases of surgically resected obstructive colitis associated with distal constrictive adenocarcinoma of the large intestine. Two cases of the obstructive colitis were radiologically suspected prior to surgery either as a separate tumor mass or diverticulosis, and another case was suggested to be a tumor seeding by colonoscopy. Grossly, five cases presented with single or multiple, shallow, well-demarcated ulcerative lesions, and the remaining two were featured with a segmental ulcerative lesion the with pseudopolypoid area. The ulceroinflammatory lesions were separated from the distal obstructive carcinoma by a skipped zone of relatively normal mucosa measuring 4-43 cm. The proximal colon to the obstructive lesions were obviously dilated except in one case. Microscopically, mucosa and submucosa were replaced by granulation tissue, and showed inflammatory cell infiltration and fibrin exudates. Muscle coat often accompanied ischemic contraction. Fissuring was noted in one case. The recognition of these lesions prior to or during surgery is stressed based on the morphological features corresponding to an ischemic change in the proximal mucosa to the primary obstructive lesion.

To analyse the clinical characteristics of children with atrial flutter(AF1), we reviewed(the medical records of the children who had been admitted and diagnosed as AF1 or 12 leads surface ECG during the period between February, 1986 and Octobe, 1990. The onset age of 25 children was evenly distributed between gestational period and upto 14 years of age. The sex ratio between boys and girls was 11:14. The cardiac abnormalities were detected in 21 children(dilated cardiomyopathy in 3, congenital heart defect in 18). In 4 children, AF1 occured in apparently normal heart. In 9 children, AF1 developed without relation to cardiac surgery(4 in normal heart, 3 in dilated cardiomyopathy, 2 in preoperative CHD). AF1 developed in 9 children within 30 days postoperatively(group A) and in 7, after 30 days postoperatively(group B). In group A, various types of operation were done. In 2 of them, AF1 persisted beyond the immediate postoperative period and 1 died of cardiac decompensation 3 months postoperatively. In group B, operative procedures before AF1 were Senning operation in 2, Fontan operation in 2, operation for tetralogy of Fallot, ventricular septal defect with severe tricuspid regurgitation, endocardial cushion defect in 1 each. Five children in group B( except 1 Senning operation and 1 Fontan operation) had significant residual atrioventricular regurgitation. The associated rhythm disturbance besides AF1 could be determined in 23 children. The sinus node dysfunction was associated in 8 ; the supraventricular dysrhythmia in 10; the ventricular dysrhythmia in 6; the atrioventricular conduction disturbance in 3, and no other associated rhythm disturbance in 6. The efficacy of various methods in conversion of AF1 to sinus rhythm were 57.1%(4/7) with DC cardioversion, 38.5%(5/13) with digoxin and other antiarrhythmic drug(amiodarone, beta blocker, quinidine, verapamil, flecainide), 25%(5/20) with pacing in esophagus or endocardium. The follow-up evaluation was possible in 24 children. Eight children were dead : 5 due to chronic decompensation, 2 due to sudden cardiac arrest, and 1 due to sepsis. Of the 16 alive children, 14 had recovered the normal sinus rhythm and the other 2 had persistent AF1. Twelve children without AF1 and 1 with persistent AF1 were on medication, Although there were none cardiac death in children without persistent AF1, 7 out of 9 children with persistent AF1 were dead. Of the 7 children with significant atrioventricular regurgitation, corrective procedures were done in 4. There were no death in these 4 children, despite of 2 cardiac death out of 3 children on whom corrective procedure were not done. In conclusion, the atrioventricular regurgitation was a significant factor in relation to the occurrence and persistence of AF1 and the prognosis was bad in children with persistent AF1. It is recommended to trat the children with AF1 associated with atrioventricular regurgitation promptly and more aggressively.

We describe a case of polyposis coli, which was followed by development of desmoid in the rectus adbominis muscle and fibromas in the mesentery during an interval of two years. This case supports the hypothesis that, in Garder's syndrome, the traumatic injury by colectomy triggers an unusual fibrous proliferation in the peritoneal cavity and incision site under the possible genetic basis.
