Lymphomatoid papulosis is a chronic disease of cutaneous atypical lymphoid infiltration characterized clinically by involuting and recurring papules, plaques, and sometimes nodules. A 51-year-old man presented with a single, coin sized, nontender, erythematous nodule on the left thigh of a 2-week duration. There was a history of recurrence and spontaneous healing of similar asymptomatic eruptions five to six times over 20 years. A biopsy specimen showed a dense, wedge-shaped dermal infiltrate that was patchy and perivascular. The cellular infiltrate was polymorphous and consisted of large atypical cells, small lymphocytes, eosinophils and neutrophils. The large atypical cells were strongly CD30(Ki-1) positive. We report a case of lymphomatoid papulosis unusually presenting as a single nodular eruption, in which the differential diagnosis between lymphomatoid papulosis and CD30(Ki-1)positive large cell lymphoma is exceedingly difficult.

PURPOSE: The incidence of clinical nephritis is much higher especially in younger ages and in about one half of the cases, it also shows nephrotic syndrome. Thus, we examine the clinical and pathologic consideration of children with lupus nephritis and their treatment modality to improve the prognosis. MATERIAL AND METHOD: Among 67 cases of children under eighteen who were diagnosed SLE, 50 patients with hematuria and proteinuria from Jan. 1980 to Dec. 1996 were selected for the review. RESULTS: The ratio of the male to female patient was 1:3.5 and the average age at the diagnosis was 11.85+/-3.2 years old. Most common clinical manifestations at the time of the diagnosis were fever and skin rashes and the common laboratory results were proteinuria, hematuria, Out of 50 cases, 33 cases had renal biopsy. The results were 17 cases of Class IV, 7 cases of Class lll, 5 cases of Class lll, 3 cases of Class V and 1 case of Class l. Different treatment modalities were carried out; Corticosteroid only 21 cases, Corticosteroid+Azathioprine 25 cases, Corticosteroid+Cyclophosphamide 3 cases, and Corticosteroid+Cyclosporine A 1 case. However, there were no significant difference in the recurrence and complete remission rate of lupus nephritis in between each treatment groups. Average follow-up period was 37+/-23 months. Of all the follow-ups, 7 patients were dead. CONCLUSION: Early diagnosis should be carried out with renal biopsy, and should be considered for vigorous therapy, which currently includes high doses of corticosteroids and immunosuppressive drugs. Among these immunosuppressive agents, azathioprine has a lower incidence of long-term complications and low costs might be recommended. In addition, regular check-up for anti-DNA antibody, serum complement concentration and appropriate moniroting and management for the adverse effects of the treatment should enable to reach the continuous remission.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acelluair basement membrane material in the lumen, and 3) cells lacking true nuclear molding and having bland chromatin pattern. The mcrphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

Angiogenesis is an essential process in tumor growth and metastasis. VEGF has been considered a leading candidate inducing tumor angiogenesis. VEGF expression was significantly correlated with clinical stage, lymph node matastasis, and prognosis of cancers of various parts of body. However, little has been known about the correlation between VEGF expression and clinicopathologic parameters in oral squamous cell carcinoma. The aim of this study was to correlate VEGF expression with the clinicopathological parameters and microvessel density. Forty six oral squamous cell carcinomas were analyzed using immunohistochemical method with primary antibodies to VEGF and CD31. VEGF expression was detected in 33 (71.7%) of the 46 cases. The microvessel density was significantly correlated with VEGF expression (P=0.002). There was no correlation between microvessel density and tumour size, clinical stage, and lymph node metastasis, respectively. VEGF expression did not correlate with the histological grade of tumour differentiation, tumour size, and clinical stages. The VEGF-positive rate seemed to be higher in patients with cervical lymph nodal metastasis than in those without it, but it was not statistically significant. In conclusion, the overexpression of VEGF in the oral squamous cell carcinoma seemed to be associated with a more aggressive course of the disease. Further study is necessary to define the role of VEGF in oral squamous cell carcinoma.

Background: Studies have reported on the usefulness of whole spine magnetic resonance imaging (MRI) in evaluating specific diseases such as spinal tuberculosis, spinal trauma, spondyloarthropathies, and multiple myeloma. In studies concerning degenerative spinal disease, sample sizes were small and some did not provide information on how symptomatic coexisting lesions were treated. We evaluated the types and prevalence of coexisting spine lesions found on whole spine T2 sagittal screening performed at the time of routine cervical and lumbar spine MRI and evaluated the efficacy of such screening in degenerative diseases of the cervical and lumbar spine. Methods: We reviewed 1,757 and 2,266 consecutive cases where whole spine T2 sagittal screening had been performed with routine cervical and lumbar spine MRI, respectively, in patients with cervical and lumbar spinal degenerative diseases. Coexisting spine lesions were documented and statistical analysis was performed to investigate significant differences according to sex, age, and initial diagnosis. Electronic medical records were reviewed to determine whether additional interventions were necessary following such findings. Results: We reviewed 1,252 and 1,689 consecutive cases of routine cervical and lumbar spine MRI respectively, with whole spine T2 sagittal screening. Of the 1,252, 419 (33.5%) patients with cervical spinal degenerative disease had coexisting lesions in the thoracolumbar spine.Patients with ligament ossification disease of the cervical spine showed a higher prevalence of coexisting spine lesions. Sixty of the 419 (14.3%) patients with coexisting spine lesions warranted additional intervention or surgical treatment. Four hundred and eighty-one of 1,689 (28.5%) patients with lumbar degenerative disease had coexisting spine lesions in the cervicothoracic spine. Forty-eight of the 481 (10.0%) patients with coexisting spine lesions warranted additional intervention. In both patient groups, older patients showed a significantly higher prevalence of coexisting spine lesions than younger patients. Conclusion Considering the minimal extra time and cost in performing whole spine screening, its application to routine spine MRI can be considered in evaluating cervical and lumbar spinal degenerative diseases.

Reactive human mesothelial cells were examined by immunocytochemical stain with intermediate fiiaments (cytokeratin [CK1, CK7, CK8, CK18, CD19], vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen (CEA), MHC class II antigen (HLA-DR), LeuM-1 (CD15), alpha1-antitrypsin(ACT), alpha1-antichymotrypsin(ACMT), CD68(KP-1) and FcyRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients transudates. The results obtained are as follows. 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cytokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative r CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes/histiocytes(CD11b, CD14, CD16, CD68, lysozyme and alpha1-antitrypsin and alpha1-antichymotrypsin) were nonreactive in resting mesothelial cells, but lysozyme and alpha1-antitrypsin were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothellal cells show a newly aberrant expression of the vimentin and carcino-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothellal cells should be further evaluated.

PURPOSE: Kissing contusion between the posterolateral tibial plateau and lateral femoral condyle is frequently found in association with a tear of the anterior cruciate liagment (ACL). The purpose of this study was to determine which ligamentous and meniscal tears are associated with kissing contusion. MATERIALS AND METHODS: We retrospectively reviewed the findings depicted by 323 consecutive MR images of the knee and confirmed at arthroscopy. For the diagnosis of disruption, ligaments, medial menisci (MM) and lateral menisci (LM) were evaluated using accepted criteria. We compared the prevalence and location of meniscal and ligamentous tears between group I (44 knees with kissing contusion) and group II (279 knees without kissing contusion). For statistical analysis the chi-square test was used. RESULTS: ACLs were torn in all 44 knees (100%) with kissing contusion, and 78 (28%) of 279 without kissing contusion. There were ten medial collateral ligament (MCL) tears (23%) in group I, and 17 MCL tears (6%), five lateral collateral ligament (LCL) tears (2%) and ten posterior cruciate ligament (PCL) tears (4%) in group II. In group I, meniscal tears were found in 22 MM (50%) and in 19 LM (43%), while in group II, they occurred in 128 MM (46%) and 128 LM (46%). In group I, 17 (77%) of 22 MM tears and 13 (68%) of 19 LM tears were located in the posterior horn, while in group II, the corresponding figures were 97/128 (76%) and 60 of 128 (47%). The differing prevalence of ACL and MCL tears between the groups was statistically significant (p<0.05), but differences in the prevalence and location of meniscal tears were not (p>0.05). CONCLUSION: Although kissing contusion was a highly specific sign of ACL tears, its presence was also significant among MCL tears. There was no signifficant difference in meniscal tears with or without kissing contusion.
