Subcutaneous fat necrosis is manifested by erythematous tender nodules on the legs, buttock or trunk and is associated with pancreatic disease including acute and chronic pancreatitis, pancreatic carcinoma, pseudocyst, pancreatic stone and other diseases. Its histologic findings are pathognomonic and reveal foci of subcutaneous fat necrosis with "ghost-like" anucleated cells with thick "shadowy wall" and surrounding inflammatory infiltrate consisting of polymorphonuclear cells, eosinophils, lymphocytes, histiocytes, foam cells and foreign body giant cells. We experienced a case of subcutaneous fat necrosis associated with pancreatic adenocarcinoma manifested by subcutaneous nodules in the buttock and lower extremities and by arthralgia of the left knee in a 67-year-old woman. Therefore, we are reporting to emphasize the importance of the skin findings of the internal disease.

Balancing the rates of cell proliferation and cell death is important in maintaining normal tissue homeostasis. The relationship among apoptosis, cell proliferation and factors influencing apoptosis according to the histologic types in chemically induced mammary tumorigenesis appears important in understanding the pathogenesis of breast carcinoma. In this study, we investigated alterations in the kinetics of cell proliferation and apoptosis during rat mammary tumorigenesis induced by 7, 12-dimethylbenzanthracene (DMBA) and we related these changes to the expressions of bcl-2, p53, and TGF-beta. Seven-week-old female Sprague-Dawley rats were divided into an experimental group (20 mg/ml DMBA by oral intubation) and a control group. The results were as follows. 1. In the experimental group, breast tumors occurred in twenty two of fifty nine rats(37.3%, 22/59), and the total number of tumors was 100 (4.5 2.0/rat). The histological classification was infiltrating ductal carcinomas (n=5), ductal carcinomas with focal invasion (n=10), intraductal carcinomas (n=36), adenomas accompanied with intraductal proliferation (n=35), intraductal proliferation (n=9), and adenomas (n=5); 2. The differentiation of terminal end bud into alveolar bud (AB) in the experimental group was significantly lower than that of the control group (p<0.05); 3. BrdU labeled tumor cells were mainly located at the peripheral portion of tumor cell nests. BrdU labeling indices were highest in ductal carcinomas, less pronounced in intraductal proliferation, and lowest in adenomas, whereas apoptosis levels were highest in adenomas, less pronounced in intraductal proliferation, and lowest in ductal carcinomas (p<0.05); 4. p53 protein was not expressed in any breast tumors. Although the expression of bcl-2 protein was highest in infiltrating and focal infiltrative ductal carcinomas (58.3%), compared with adenomas, intraductal proliferation, and intraductal carcinomas (p<0.05), the extent of its expression was less than 1% of all tumor cells; 5. TGF-beta was mainly expressed in the central portion of tumor cell nests rather than in peripheral portion, and TGF-beta immunoreactive tumor cells displayed good differentiation and did not reveal BrdU immunoreactivity. TGF-beta labeling index of infiltrating and focal infiltrative ductal carcinomas was significantly higher than that of intraductal carcinomas, intraductal proliferation, and adenomas (p<0.05). Based on these results, it is thought that high cell proliferation and the suppression of apoptosis are closely associated with DMBA-induced rat mammary carcinogenesis. However, the suppression of apoptosis is not related to p53 mutation, bcl-2, and TGF-beta. TGF-beta seems to be reversely related to tumor cell proliferation but closely associated with the progression of the tumor, especially an invasion of breast carcinomas.

Congenital hypoprothrombinemia is a rare congenital coagulation defect. The clinical signs are manifestation of generalized tendency such as; mucosal bleeding, hypermenorrhea and post tooth extraction hemorrage. It is associated with prolongation of PT and PTT with normal thrombin time and decreased serum prothrombin level. A case with congenital hypoprothrombinemia was experienced by the authors. A 36 days old male baby was admitted with palor skin and vomiting started one day before admission. Right side brain parenchymal hemorrhage and left shift of lateral ventricle were on brain CT scan. Prologation of prothrombin time and partial prothrombin time with decreased serum prothrombin level were resulted. Serum factor I, V, VII, VIII, IX and X were within normal level. We report a case congenital hypoprothrombinemia with a brief review of relaed literatures.

On a total 233 sera from the VDRL reactive patients without a history of syphilitic symptoms or treatment for syphilis, TPHA and 19S(IgM)-FTA tests were performed, Also the reactivities of the 19 S (IgM)-FTA test in relation to the VDRL and the TPHA titers were observed. The results are summarized as follows: 1. Among 233 sera, 103 sera(44%) showed negative results in the 19S(IgM)- FTA test. 2. Reactivities of the 19 S(IgM)-FTA test were significantly increased in relation to the VDRL, titers arnong 233 sera reactive in the VDRL test: 47% in the VDRL titer 1: 1, 61% in 1: 2, 71% in 1: 4, 62% in 1: 8, 96% 1: 16 or more. 3. There was no relationship statistically (IgM)-FTA test and the TPHA titers. It can be derived from the above results that when a person with no history of treatment for syphilis and clear of any signs of syphilis shows a positive reaction in the VDRL test, he is less likey to be a syphilis patient when the VDRL titer is low.

An immunoperoxdase technique in electron microscopy was used to investigate the ultrastructural site of keratinolytic proteinase (KPase) of M crosporum cans in sections of skin from guinea pigs infected with the same organism. Ultrastructurally, the KPase was present only in the cell walls of the invading dermatophytes as a continuous deposition of the electron-dense reaction product on the inner and outer aspects of the cell wall of the fungal hyphae without deposition in the keratin surrounding the invading hyphae. Our results suggest that the KPase may not play an absolute role in the invasion of dermatophytes into keratinized tissue in vivo.
