1.Ectopic Umbilical Liver Associated with Intrauterine Fetal Death: An autopsy case.
Korean Journal of Pathology 1996;30(3):269-271
Ectopic liver in the umbilicus is very rare, and a few cases have been reported in the world. It is thought that an increased intraabdominal pressure resulting in entrapment of liver cell nests causes the presence of liver in the umbilicus. It relates to neonatal problem such as infection. We report a case of ectopic umbilical liver in a stillborn male of 28 gestational weeks. His mother discovered loss of fetal movement 2 days before admission, and intrauterine fetal death was diagnosed by ultrasonography. Grossly, the umbilical cord was markedly swollen. On cut section, a well circumscribed, oval round, tan-colored soft mass was noted within the cord. Histologically, it consisted of hepatic cords without bile ducts. The umbilical vessels were distorted by the ectopic liver, and contained thrombi. These findings suggest that ectopic umbilical liver results in the intrauterine fetal death

S-100 protein is a mixture of three proteins, that is, S-100 ao(aa), S-100 a(ab) and, S- 100 b(bb). Twenty-two case, of sweat gland tumors were stained with immunoperoxidase technique (ABC method) for the presence of S-100a and b-subunit. Four syringomas, four eccrine poromas, two eccrine porocarcinomas, two ecerine spirdeiomas, one papillary eccrine adenoma, three clear cell hidradenomas, three mixed tumr rs of the skin, two papillary syringocystadenomas, and one cylindroma were included. All specimens were formalin-fixed and paraffin-embedded. The results were as follows : 1) The staining patterns of anti-S-100a and b-protein antibodies we e simillar to those of anti-S-100 protein antibody except in eccrine poroma and porocare nomal. 2) In eccrine poroma and porocarcinoma, scattered S-100-positive dendritic cells within tumor cell nests were stained by S-100-protein antibody (3/6), but not by anti-S-100a protein antibody. S-100p is present in normal Langerhans cells. Therefore this finding suggests that these cells niay be Langerhans cells

We report a case of hereditary angioedema in a 48-year old female patient. She experidenced facial edema and dyspnea 5 to 6 times for a year. Similar episodes developed on some members of her family, especially her sisters and father. We examined her and her sister's serum complement levels. The results showed decreased levels of C1 esterase inhibitor and C4, compared to normal levels. We treated the patient with danazol effectively.

There was no definitive reported cases of urinary calculi. This study is to estate the value of urinary calcium, magnesium, uric acid and magnesium/calcium ratio in cases of urinary calculi. The amount of calcium, uric acid and magnesium in 24 hour urinary excretion was measured by OCPC, Uricase and titan yellow method in 56 cases of upper urinary calculi compared with 35 control group.The results were summerized as follows.l. The mean values of 24 hour urinary excretion of calcium were 193+/-26mg/day in stone formers and 15l+/-25mg/day in control group. The 24 hour urinary excretion of calcium in the stone formers were significantly higher than those of the control group. 2. The mean values of 24 hour urinary excretion of uric acid were 498+/-40mg/day in the stone formers and 371+/-6mg/day in the control group. The 24 hour urinary excretion of uric acid in the stone formers were significantly higher than those of the control group. 3. Urinary magnesium values have not been shown any significant differences between the group with urinary calculi and those of control group. 4. The mean values of 24 hour urine of magnesium to calcium ratio was 1.01+/-0.95 in stone formers and l.42+/-1.31 in the control group. The magnesium to calcium ratio in the stone formers were significantly lower than those of the control group. These results suggest that increased urinary calcium and uric acid level may play some role in the genesis of urinary stone but urinary magnesium value was not different in the two groups. We think that a decrease in the urinary magnesium to calcium ratio was the results of increased excretion of calcium rather than lowered excretion of the magnesium for the stone formers.

BACKGROUND: A definition of granuloma is a focal chronic inflammatory response to tissue injury evolved by a poorly soluble substwice characterized by the accumulation and proliferation of the mono-nuclear histiocytic cells. The accuracy with which rnononuclear cells may be identified in skir. is much improved by the use of both heteroantisera and monoclonal antibodies directed against selected cellular antigens, OBJECTIVE: Our purpose was to examine the staining patterns of anti-lysozyme, anti-a-1-antitrypsin, anti-S-100 protein antibodies, and MAC-387 monoclonal anibody in granulomatous skin diseases. METHOD: We performed imminoperoxidase staining(the labelled str prvidin-biotin peroxidase complex method on the formalin-fixed, paraffin-embedded tissue specimens of granulomatous skin diseases. RESULTS: S-100 protein positive dendritic cells were demonstrated in the granulomatous infiltrates as scattered pattern and MAC-387 positive cells were predominantly found in the center of granulomas, The staining pattern and percentage of positively stained cells of a--antitrypsin were similar to those of lysozyme. A1Pha-1-antitrypsin and lysozyme positive cells w re present in the center as well as lymphohistiocytic infiltrates of granulomas. CONCLUSION: These data sugget that histiocytes are composed of heter igeneous groups of cells such as the mononuclear-phagocyte system and dendritic cell system.

The allopurinol hypersensicivity syndrome is a rare, but life thereaning immunologic reaction of allopurinol therapy, characterized by multiple abnormalities such as fever, rash, decreased renal function, hepatocellular injury, leukocytosis, and eosinophila. It may require prolonged hospitalization and occasionally involves residual morbidity. Three patients developed erythematous skin eruption three to five weeks after beginning therapy with allopurinol. The clinical, laboratory, and histologic findings of these patients were compatible with a allopurinol hyperensitivity syndrome.

BACKGROUND: Chronic cutaneous lupus erythematosus(CCLE) is a well-known disease entity. But there has been no data about its clinical behavior and histopathologic features in Korea. OBJECTIVES: This study was conducted to elucidate the clinical, laboratory, and histopathologic features of CCLE, and the relationship between CCLE and SLE. MATERIALS AND METHODS: We investigated 48 cases of CCLE that visited the department of dermatology at the Seoul National University Hospital from January 1990 to June 1997. Medical records and biopsy slides were reviewed.

BACKGROUND: It is a popular notion that cutaneous ageing includes two distinct phenomenon; true ageing, a universal presumably inevitable change attributable to the passage of time alone, and photoageing, changes attributable to chronic habitual sun exposure that are neither universal nor inevitable. Numerous investigations with experimental animals, in vitro skin models have been conducted, although, few histological studies to date have attempted to announce fundamental morphological changes with innate ageing. OBJECTIVE: We compared skin derived from the breast of old and young persons using light microscopy to discern structural changes in epidermal and dermal morphology with advancing age. METHODS: The histological, immunohistochemical studies were performed with normal skin sections of thirty donors who were diagnosed with breast cancer. They were classified into three age cohort groups; nine into group I (22 to 38), twelve into group II(40 to 52), and nine into group III(54 to 87). We chose the breast as an area that might closely resemble intrinsically aged skin. This region is relatively shielded from photoageing by its anatomical location. Analysis of data was performed using the Kruskal-Wallis and ANOVA test for dermal parameters based on a 5-point rating scale, and a simple regression test for a positive rate of immunoreactants. Results : 1. Light microscopic appearance of aged skin revealed a more flattened epidermis than young skin. There was no trend for an increase in epidermal melanin content per unit area on Fontana-Masson staining. There was an age-associated decrease in the Ki-67 positive rate(p<0.001), the density of Ki-67 positive cells declined approximately 1.16% per decade in photoprotected skin(p<0.001). The number of S-100 positive cells declined approximately 4.4/mm width along the dermo-epidermal juction per decade in photoprotected skin(p<0.001). The expression of differentiation markers(keratin 1, involucrin, filaggrin, loricrin) were not different among the three age cohort groups. 2. With advancing age, there was an attenuation in the number and diameter of elastic fibers in the papillary dermis and an increase in the number and straightness of the same fibers in the reticular dermis. The collagen fibers are arranged in sparse bundles in disarray, and/or aggregates of loosely woven, straight fibers in the aged skin. There was an apparent, age-related decrease in the stainability of ground substances in the papillary dermis on colloidal iron staining. Conclusions : Our data documents semi-quantitative differences among three groups in intrinsically aged breast skin and provide the framework for future research to evaluate the ageing process.

Hand tumorsare many and varied, although benign tumors are common. The pathology and histology of these tumors are not unlike these characteristics of the tumor when it occurs elsewhere. Early diagnosis and proper treatment of all hand tumors have been emphasized since the growth of tumors and pain can cause disturbance of intrinsic function of the hand. For the period of 10 years from 1977 to 1986, 105 cases of hand tumor were treated surgically and the results of clinical observation were as follows ; l. Among 105 cases, benign tumor was 101 cases(96.2%) Bone origin tumor was 20 cases, in which enchondroma and enchondromatosis were 17 cases(70%). Soft tissue origin tumor was 85 cases, in which ganglion was 54 cases(63.5%). 2. Among 105 cases, 42 cases were male and 63 cases were female. In age distribution, it showed even distribution. 3. In the duration of wymptom, 51 cases were below 1 year(48.6%). 4. The tumor occured 85 cases in soft tissue, 14 in phalanx, 7 in metacarpal and 1 in carpal bone. 5. The tumors were treated by excision or curettage and bone graft with good improvement, but postoperatively recurred in 2 cases of Hemangioma. Ampuation was performed in 3 cases of malignant tumors without recurrence.
