The automation in surgical pathology, particularly in the reporting and encoding system using personal computers has been greatly improved in recent years, but the computerization of microscope slide labelling has not been improved. The authors have developed database program for slide labelling using FoxPro 2.5 and FoxBASE SCOUNIX 2.1.2: For I year during trial an effect has been put forward to simplify and organize the labelling work in routine surgical pathology. The program is now become easily applicable to the labelling work without disturbing the normal flow in a pathology laboratory. It is possible to get information concerning how many paraffin blocks and H&E slides have been made, as well as what kind of special stains have been requested for each case. The authors think that the computerization of labelling work in routine surgical pathology is a fairly easy task, and this should simplify the labelling work at a lower cost, diminish the workload of a typist or technician, and indirect information concerning the workload in a pathology laboratory can be calculated.

There is no definite histological criteria which can predict the biologic behavior of meningiomas, although resectability is the most important factor in terms of recurrence. For grading meningiomas, various factors have been studied, such as hypercellularity, nuclear pleomorphism, small cells with high N/C ratio, prominent nucleoli (PN), frequent mitosis, loss of architecture, focal necrosis (FN). We investigated 116 meningiomas to evaluate the correlation between the factors and the proliferative activity using AgNORs and MIB-1 labelling index (LI). They were divided into 3 groups: Group A includes meningiomas with none of the factors; group B with one of the factors; group C with two or more factors. MIB-1 LI was correlated with each factor, but AgNORs was not. There was a statistical difference among group A (<1.28%), B (2.7%) and C (5.1%) (p<0.05) using MIB-1 LI. FN was the most frequently associated with other factors, and it had the highest MIB-1 LI (6.31%). MIB-1 LI of group B was 5.1 2.3%. In group B, the most frequent combination was FN and PN, and it showed the highest MIB-1 LI (5.74%). This study indicates that FN and PN are important for diagnosis of atypical meningioma, and MIB-1 LI appears to be a useful method for estimating the proliferative activity of meningiomas, and 5% or more of MIB-1 LI could help in making a diagnosis of atypical meningioma.

We report a case of kerion celsi caused by Trichophyton verrucosum in a 4-year-old male. He presented painful, tender, indurated, boggy masses discharing pus on the vertex and occiput. Kerion celsi caued by T. verrucosum was diagnosed by the characteristic gross and microscopic findings of the colony on the Sabourauds glucose. agar. The possible source of infection was searched and wq found that he raised the cattles in his house. They had multiple, scaly, whitish plaques on the skin and T. verrucosum was identified from the hairs of the lesions. He had been treated with griseofulvin and prednisolone, and all lesions were cleared leaving partial alopecia in 2 months.

T. verrucosum Infection has been reported for the first time in 1986 in Korea and has been increasing progressively. To evaluate the progress of clinical and histopathological change of dermatophytosis caused by T. verrucosum, inoculation study, using T. verrucosum isolated from infected human (human strain) and from infected cattle (cattle strain), was done in 24 male albino Hartley guinea pig. Their clinical and histopathological changes were evaluated. In addition, comparison for the growth rate between human strain and cattle strain on Sabouraud's glucose agar was made. The results were as follows: 1. Growth rate on Sabouraud's glucose agar: Cattle strain showed significantly more rapid growth rate than human strain on Sabouraud's glucose rate at 25℃ and 37℃. And cattle strain showed more rapid growth rate at 37℃ than 25℃. But human strain showed no significant difference of growth rate at both temperature. 2. Clinical findings: Initial erythema, scale and crust were developed about 8th after inoculation. All three findings reached maximum severity about 12th to 16th day and disappeared about 30th to 34th day after inoculation. There was no significant difference in progress of erythema, scale and crust between cattle strain and human strain. 3. Histopathological findings: Although mild acanthosis was noticed on the 3rd day after inoculation, the other findings including parakeratosis, intraepidermal abscess, spongiosis and vascular change, cellular infiltration were found on 9th day after inoculation. They reached maximum severity on the 12th day and lasted to the 25th day after inoculation. After that, all three findings were decreased gradually between 29th day and 33th day. On the PAS staining, hyphae and spores were found on the 6th day and disappeared on the 21th day after inoculation. 4. In trichophyton skin test, all of the 24 guinea pigs became positive within average 9.83±1.17 days These findings suggested that dermatophytosis caused by T.verrucosum induced rapid cell mediated immunity and contributed to rapid resolution of the lesion.

The mixed gangliocytoma-pituitary adenoma is a very rare intracranial neoplasm, and it is frequently associated with endocrine symptoms; acromegaly, Cushing's disease, galactorrhea and amenorrhea. Morphologically it shows a mixture of gangliocytoma and pituitary adenoma in various proportions. In the area of gangliocytoma, there is no neoplastic glial component. The portion of pituitary adenoma consists mainly of chromophobe cells. There are three hypotheses in its histogenesis. We report a case of a 41 year-old lady presented with acromegaly and amenorrhea existing for 3 years. On magnetic resonance image, there is a dumbell-shaped mass in the sellar region. Histologically it showed typical features of mixed gangliocytoma-pituitary adenoma. This case is presented in the view of its rarity and interesting possible histogeneses.

Kaposi's varicelliform eruption is a more or less generalized infection of the skin, and sometimes of internal organs, with herpes simplex, vaccinia or Coxsackie virus A 16; it appears in people who have atopic dermatitis or some other skin diseases. There is a predilection for infants and children, but no age-group is exempt. We reported 3 cases of Kaposi's varicelliform eruption with atopic dermatitis. They had characteristic multiple umbilicated vesicles on the sites that atopic dermatitis had been involved. A 14-year-old boy and a 2-month-old infant had fever. A 17-year-old boy had wide-spread vesicles. All three patients showed multinucleated giant cells on Tzanck test, that suggests herpes simplex virus origin. They were treated with acyclovir. Within 1 to 2 days after the initiation of the therapy, new lesions had ceased to develop. Most of the lesions were cleared in 7 days without complication.

The search for a new flap with minimal donor morbidity has been pursued by many plastic surgeons. Numerous donor sites available for microsurgical composite tissue transplantation have been described owing to the tremendous advances made in the field of microsurgery. To be suifable for use as a free flap, a sizable vessel must be included within the tissue, leading to significant donor morbidity. There have been studies for prefabrication of an axial pattern flap in an effort to create a new flap, but most of these methods relied solely on revascularization of a preexisting composite tissue. Our experiment, using an isolated femoral artery and vein as the main pedicle, led to formation of a capsule flap through a normal foreign body reaction between 2 silastic sheet implants. On this induced capsule flap, a skin graft was performed and a total of 40 axial pattern capsulo-cutaneous flaps from 20 Sprague-Dawley rats were successfully obtained after nearly 12 weeks through 4 stages of experiment, including a delay procedure at the second stage. Pathology revealed neovascularization, and abundantly impregnated vascular structures near the pedicle were observed along with random pattern collagen fibers. The skin graft took 100% on this newlyformed axial pattern capsular flap and thus implied that the capsule structure was able to survive on it`s own and was able to support skin grafts. This new flap using only the isolated artery and vein structure can be induced according to various needs with minimal donor morbidity.

This study was conducted to assess the prognostic value of tumor angiogenesis and Cathepsin-D in breast carcinoma, by correlating them with other clinicopathologic prognostic factors. In order to estimate microvessels within the tumor, an immunohistochemical method using monoclonal antibodies for factor VIII-related antigens (DAKO-vWf, F8/86) was used, and they were counted (perx200 field) in the most active areas of neovascularization. For the expression of Cathepsin-D, an immunohistochemical method using monoclonal antibodies (Novocastra, NCL-CDm) was performed. The microvessel count ranged from 8 to 346 per x200 field and the mean (+/-SD) was 72.46+/-54.96. The microvessel count was correlated with the estrogen receptor status, and it was also correlated with the tumor size when it was graded into four groups (1-33, 34-67, 68-100, >100), but was not correlated with other clinicopathologic parameters. Cathepsin-D was expressed in 40% (46/115) of the cases, but it was statistically correlated with the tumor size only. In conclusion, the expression of Cathepsin D and the degree of angiogenesis in breast cancer showed a correlation with the tumor size only. Therefore, they do not appear to be good prognostic parameters, according to the present study.

OBJECTIVE: To study the clinical characteristics on translocation of intrauterine device and the methods of removal. METHODS: A retrospective review was performed on 77 cases of translocation of intrauterine device from June 1994 to December 2002. RESULTS: Among 77 cases undergoing removal of intrauterine device, 17 cases (22.1%) were translocted intraperitoneally. Fifteen cases were removed by laparoscopy, 2 cases were by laparotomy and there was no specific postoperative complication. The incidence of intraperitoneal translocation was not related to the type of IUD. Between intrauterine and extrauterine translocation, the incidence of symptoms were not different, but low abdominal pain were slightly increased in extrauterine (35.3%) than intrauterine (10.0%) group. The time lapse after insertion of IUD was ranged from 1 month to 35 year, the mean duration was 9.39 year, that was not related to the incidence of intraperitoneal translocation. In the cases of extrauterine translocation, the mean hospital day was significantly increased (p=0.001), the mean duration was 2.5 day (1-7 day), compaired with 0.7 day (0-6 day) of the cases of not translocated. CONCLUSION: As the type of IUD or symptoms, it is difficult to anticipate the possibility of the intraperitoneal translocation of IUD. But, in cases of extrauterine translocation of intrauterine device, the incidence of low abdominal pain was slightly increased, and ring type IUD was rarely extrauterne translocated. So, it is necessary to further study what factors contribute the extrauterine translocation of IUD.

This study was carried out to evaluate the aberrant expression of p53 protein using immunobistochemical method in 54 surgically resected liver cell carcinomas and to correlate it with clinical and pathological findings. Twenty five out of 54 cases(46%) showed positive reaction in the nucleus of liver cell carcinoma and negative reaction in associated 30 cases of cirrhosis, one case of adenoma and two cases of adenomatous hyperplasia. The p53 protein expression was associated with alpha-FP level(p<0.05), but not associated with HBsAg positivity. It was significantly associated with WHO classification, Edmondson-Steiner grade and nuclear grade p53(p<0.05), but not associated with tumor size, capsule formation, portal vein invasion, cirrhosis in surrounding tissue, Eggel classification, special cell type and mitosis. In conclusion, our results suggest that the aberrant expression of p53 protein can be an advisory factor, at least, for prognosis evaluation.
