BACKGROUND: Acantholysis can be seen occasionally in the cutanous squamous cell carcinoma(SCC) as a result of degenerative changes of neoplastic cells. OBJECTIVE: This study was done to investigate the keratin attern and a wide range of immunohistochemical features of acantholytic cells of cutaneous SCC. METHODS: Seventeen cases of SCC showed acantholytic cells histoloieally and formalin-fixed, paraf-finembedded biopsy specimens from them were stained by ABC(avidin-biotin-peroxidase complex) staining. Fourteen biopsy specimens from 14 cases of SCC were staincd with 3 monoclonal anti-keratin antibodies(CAM 5.2, MAK-6, and 34bE12) and 17 biopsy spec:mcns from 17 cases of SCC were stained with antibodies agairist CEA(carcinoembryonic antigen), vitamin, S-100 protein, Factor VIII-R Ag, LCA(leukocyte common antigen), and lysozyme. RESULT & CONCLUSION: Acantholytic cells of 14 cases of SCC showed consistently negative staining with CAM 5.2. The acatholytic cells showed a wide range of reactivity with MAK-6 from negative to moderately strong positivity and with 34pE12 from negative to strong positivity. A few acantholytic cells of 6 cases of SCC showed weakly positive staining with anti-CEA antibody, but acantholytic cells of all 17 cases showed consistently negative staining wit,h the other antibodies.

BACKGROUND: Before the introduction of the antinuclear antibody test (ANA), the lupus erythematosus (LE) cell test was a useful diagnostic test for systemic lupus erythematosus(SLE) But, the ANA test has replaced the LE cell test in virtually all laboratories as the current routine test for SLE. However, because the LE cell test is still performed in some laboratories, the authors compared the LE cell test with the ANA test to reevaluate the LE cell test. METHODS: A total of 522 cases were evaluated from Aug. 1990 to Aug. 1994. In these cases, the LE cell test and the ANA test were performed simultaneously, and the results were compared. The authors defined the 'True LE Phenomenon' as only when the LE cell test results agreed with the anti-histone antibody pattern of the ANA test. RESULTS: Of the total 522 cases, 56 cases(10.7%) were SLE. The LE cell test was positive in 22 cases(39.3%) and the ANA test in 56 cases(100%). The LE cell test produced 6(27%) false positive cases and 3 (8.8%) false negative cases. Therefore, the sensitivity of the LE cell test that was verified by the ANA test was only 28.6%. On the other hand, the sensitivity of the ANA test was 100%. In 2 cases, the LE cell results were different in repetitive tests although the ANA results were the same. In 2 other cases, it was impossible to interprete the results of the LE cell test because of severe leukopenia. CONCLUSIONS: The authors concluded that the LE cell test showed markedly low sensitivity and a high false positive and false negative rates for SLE, and that the LE cell test was difficult to perform and interpret accurately due to numerous interfering factors. Therefore, for accurate diagnosis of SLE, the LE cell test must be replaced by more definitive and quantitative immunologic tests in all laboratories such as the ANA test.

The functioning filtering bleb constructed after trabeculectomy in glaucomatous patient might be fail after cataract operation probably due to transient collapse during cataract extraction and inflammatiry reaction of the filtering bleb which result in unsuccessful intraocular pressure control. To compare if the results were identical in cases with the use of encircling band to enlarge the aqueous absorbing scar tissue to trabeculectomy, intraocular pressure was followed for more than 6 months after cataract extraction and posterior chamber lens implantation in 7 eyes that previously underwent silicone tube insertion with the use of encircling band. There were no cases with increased intraocular pressure needed to control postoperatively. Therefore it could be possible to concluded that inflammatory reaction of the filtering bleb or transient collapse during cataract extraction has no negative influences on intraocular pressure in silicone tube implanted eye using encircling band.

Stein-Leventhal syndrome is a clinicopathological entity characterized by chronic anovulation and sclerotic ovaries. Clinically, the affected patients typically present their third decade with a history of premenarchal obesity and postmenarchal onset of oligomenorrhea or amenorrhea, infertility, and clinical evidence of increased androgen production. In some patients, there are estrogenic phenomena such as menometrorrhagia with or without endometrial hyperplasia or carcinoma. Several studies have indicated that there may be an increased incidence of ovarian neoplasia in polycystic ovaries. Recently, we experienced two cases of polycystic ovaries assotiated with endometrial carcinoma in premenopausal women, who had clinical characteristics of Stein-Leventhal syndrome; one of the cases had additional serous cystandenofibroma.

This is a report of the clinico-pathologic findings in six cases of histologically verified malignant meningiomas-three hemangiopericytic and three anaplastic types. They were three males and three females and two of them were reoperated for recurrence. The hemangiopericytic types had similar angiographic and macroscopic features and malignant characteristics such as increased mitoses. The anaplastic types lacked typical arrangement, but had a large number of mitoses, increased cellularity, focal necrosis, pleomorphism, anaplasia, and the adjacent normal parenchymal infiltration. However the metastasis was not yet proven in these cases.
