This study was conducted to set up a common mechanism for varying phases of focal segmental glomerulosclerosis(FSGS) by comparing the morphological differences between human FSGS and changes in 5/6 renal ablation animal model, which has been accepted as experimental prototype for hyperfiltration theory as pathogenesis of FSGS. Both the human and the experimental rats showed very similar changes such as segmental glomerulosclerosis, vacuole formations or inclusion of small granules of podocytes, appearance of foamy cells in the capillary lumina, eosinophilic deposits along the mesangial area, and focal atrophy of tubules with associated interstitial fibrosis. The halo, frequently seen in human FSGS, is due to detachment of visceral epithelium from basement membrane, however, did not appear in the experimental rat specimen. On the other hand, the foamy cells and hyalinization were more frequently noted in the rat series and even involved the arterioles. The mesangial proliferation never appeared in the rat series occasionally found in human FSGS. In conclusion, the pathogenesis of FSGS cannot depend solely on the hyperfiltration theory of hemodynamic derangement, but has complex impairment of visceral epithelium and cells forming the constituents of basement membrane.

Carcinosarcoma, often referred to as "malignant mixed tumor" is a rare neoplasm, but this tumor occurs in various organs, including the gallbladder. We report herein a carcinosarcoma of the gallbladder which consisted of adenocarcinomatous and undifferentiated sarcomatous ares, the latter differentiating towards abundant osteoid and calcified but nonlamellated bony trabeculae formation. There are 18 reported cases of this type tumor of the gallbladder in the literature.

A 65-year-old female patient experienced melena for 10 days. Gastroduodenoscopy revealed a tumor in the duodenum, a portion of which was taken for biopsy, which showed a malignant tumor. She underwent pancreatoduodenectomy, and the final tumor pathology revealed invasive ductal carcinoma from the breast, which was confirmed using immunostaining of milk fat globule antigens. Nineteen years before, she had received a radical mastectomy due to invasive ductal carcinoma of the right breast. Hematogenous metastasis occurs in 33% of patients with breast cancer, mainly to the liver and lung, in invasive ductal carcinoma (IDC), and to the gastrointestinal tract, peritoneum, and retroperitoneum in invasive lobular carcinoma (ILC). Solitary metastatic duodenal tumors from breast cancer, especially IDC, is rare, particularly after a long time. This rare case is presented with a literature review.

Thirty nine cases of multiple primary malignant tumors examined at the Department of Pathology, Keimyung University School of Medicine during the period from November 1974 through March 1986 were analysed clinicopathologically. The findings are as follows: 1) Thirty nine cases had synchronous lesion and six cases metachronous lesion. The second primary malignancy occurred mean 4.7 years after the first malignancy in patients with metachronous lesion. 2) The age at diagnosis of the first malignancy ranged from 26 to 76 years, the average being 51.8 years. The male-female ratio was slightly less than 1:1.2. 3) The most commonly involved site in multicentric origin was gastrointestinal tract (44.4%) with all adenocarcinoma and the second urogenital system (29.6%). In cases of different tissues or organs (11 cases), ovary was the most frequent site (5 cases), followed by cervix (4 cases). 4) Multiple primary malignant tumors of urogenital system were all eight cases and six cases among them (75%) had smoking and drinking habits. 5) The detailed informations about possible environmental, familial and host factors necessary for the investigation of multiple primary tumors were lacking in most cases. Therefore, the history taking with special attention to these factors must be carefully recorded. And also, we suggest that in the high-risk individuals, careful follow-up and thorough search for early cancer detection or prevention should be taken.

A case of multiple hemangioendothelioma of the cauda equina nerve roots and conus medullaris is described. This case is the first report of intradural multiple hemangioendothelioma in Korea. A 74-year-old woman presented with a 4-month history of progressive bilateral leg weakness and lancinating leg pain especially at night. Magnetic resonance image revealed multiple enhancing nodular masses in the cauda equina nerve roots and pial surface of the conus medullaris. We performed total removal of conus medullaris mass and partial removal of two nerve rootlets masses. Two lesions were histologically examined and found to be hemangioendotheliomas

BACKGROUND: The purpose of this study was to investigate the association between diabetes and depressive symptoms among Korean women. METHODS: We performed an analysis of data for 6,572 women aged 30 or over obtained from the Fifth Korean National Health and Nutrition Examination Survey conducted in 2010 to 2011. We examined the presence of depressive symptoms and the treatment of depression according to diabetes status. RESULTS: The presence of depressive symptoms was observed in 22.6% of subjects with diabetes. In the multiple logistic regression model, diabetes was associated with an increased risk of depressive symptoms (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.20 to 1.21) but the treatment of depression among diabetics was less common (OR, 0.54; 95% CI, 0.54 to 0.55). Uncontrolled diabetes (glycosylated hemoglobin > or = 7%) was associated with an increased risk of depressive symptoms (OR, 1.71; 95% CI, 1.69 to 1.73) among diabetics. CONCLUSION: Physicians should manage individuals with diabetes in consideration of the presence of depressive symptoms, especially in those with uncontrolled diabetes.

Small cell carcinoma does originate from APUD cells of any parts of the body. Usually the cases discovered in the lung and have poor prognosis. In esophagus only about 100 cases are reported world widely after McKneown reports in 1952 and only 2 cases were reported in Korea. There was a cese of small cell carcinoma developed multiple lesions in esophagus but no reports said that small cell carcinoma developed syncronously in esophagus and other organs. We are to report a case that showed a multiple lesions in esophagus and cardia. The patient 60 yeata old man, has suffered from the substernal discomfort and significant weight loss for one month.

The characterisitic finding of hypertrophic cardiomyopathy is left ventricular hypertrophy without dilated chamber. Echocardiographic studies of patients with pheochromocytoma in the past have revealed both dilated and hypertrophic cardiomyopathies, as well as obstruction of the left ventricular outflow tract. We report this case because we experienced a pheochromocytoma patient who had reversible hypertrophic cardiomyopathy which might be related with circulating catecholamine level.
