Fibrous histiocytomas are characterized by a variable combination of cells with fibroblastic and histiocytic features. They exhibit a distinctive but inconstant cellular arrangement referred to as a storiform or cartwheel pattern. Considerable corfusion has enveloped these tumors as a result of their various terminology-fibrous histiocytoma, dermatofibroma, sclerosing hemangioma, fibroxanthoma, subepidermal nodular fibrosis, xanthogranuloma, giant cell tumor of tendon sheath. A histologically benign but locally infiltrating, 15 * 20cm sized, fibrous histiocytoma was found in the posterior aspect of left thigh of a 17-year-old man. The tumor was incompletely excised due to adhesion of the tumor mass to sciatic nerve and then radiation therpy was combined, Histogenesis and prognostic aspects of the tumor are discussed.

The onset of systemic scleroderma in the first. decade of lif occurs in less than 1.5% of instances. Systemic sclerodrma in childhood have been characterized by less severe visceral involvement and a benign course We report a boy, aged 7 years, with a history of Raynaid; phenomenon and dysphagia. He had a mask-like face, flexion contracture of hands and knee joints, digital pitting scars, ichthyosiform skin change on leg and hyperpigrnented induration on all extremities and trunk. Antinuclear antibodies were positive in nucleolar type and Scl-70 antiocy was also present. On radiologie study, the pattern of reflux esophagitis and resorption of the listal ends of all phalanges were nated. Histopathological findings were compatible with sclerodma. He was treated with Penicillamine-D and oral corticosteroic with good improvernent.

PURPOSE: To assess the role of the preoperative portal vein embolization (PVE) in patients in need of major hepatectomy. MATERIALS AND METHODS: Total of 11 cases consisted of Klatskin tumor (n:6), gallbladder cancer (n=2), and hepatocellular carcinoma (n=3). After percutaneous transhepatic puncture of portal vein (right:7, left:4), the embolization of 1st order branch of right portal vein was done with Gentamicin soaked Gelfoam cubes. Radiologically, the angle between the middle hepatic vein and the inferior vena cava was measured on pre- and post-PVE CT (F/U :10 days) to evaluate the hypertrophy of the left lobe. Clinically, amount and nature of the drained bile through the PTBD tube of both lobes were analyzed in 5 patients with Klatskin tumor. The interval between PVE & operation was 10-24 days. Operative findings & the changes of postop. total bilirubin were analyzed and the complication after procedure was checked. RESULTS: There was decrease in mean angle between the middle hepatic vein and the inferior vena cava from 35.9 degree to 23.9 degree, but it was insignificant statistically (p=0.09). The embolization of right portal vein was done and there was increase in amount of drained bile from the nonembolized left lobe by 2-3 folds 8-14 days after PVE. The color and consistency between both lobes were significantly different; right lobe was darker in color and softer in consistency. Postoperative total bilirubin increased by 2-3 folds 1 to 4 days after PVE and normalized 10 to 14 days after PVE. Most of the patients had mild abdominal pain and fever after PVE and 1 patient had localized hematoma at puncture site which was subsided spontaneously. CONCLUSION: The preoperative portal vein embolization is a useful method for minimizing postoperative liver failure in patients in need of major hepatectomy.

This retrospective study was undertaken to investigate the current clinical trend in the management of ectopic pregnancy. 562 patients of ectopic pregnancy were admitted and managed at the Department of Obstetrics and Gynecology, Chonbuk National University Hospital from Jan. 1. 1985 to Dec. 31. 1996. All cases had a reliable medical record and were divided into two groups, of which group A includes patients admitted from Jan. 1. 1985 to Dec. 31. 1990, group B from the Jan. 1. 1991 to Dec. 31. 1996. The results were obtained as follows. 1. The number of cases of ectopic pregnancy were 248 in group A and 314 in group B. 2. The age group of 20 to 29 years of age was top ranked in group A(49.6%) as well as in group B(46.8%). The age group of 30 to 39 years was 43.2% in group A and 46.6% in group B, respectively. 3. In group A, the case who experienced two deliveries was 31.9%, and nulliparous woman was 30.6%. In group B, the case who experienced two deliveries was 33.1%, nulliparous woman was 33.1%. 4. On reviewing the past medical history, ectopic pregnancy was 11.2% in group A, 10.8% in group B, respectively. Pelvic inflammatory disease was 8.1% in group A and 11.0% in group B, respectively. 5. The interval between the last menstrual period and the onset of symptoms was prevalently in 4 to 8 weeks(64.5% in group A, 61.8% in group B). The terval of 12 weeks or more was 2.0% in group A and 6.0% in group B, respectively. 6. In considering the chief complaints, low abdominal pain was 85.9% and vaginal spotting was 69.0% in group A. On the other hand, low abdominal pain was 91.4% and vaginal spotting was 76.4% in group B, meanwhile nausea and vomitting was 8.6% and dizziness was 3.5% in group A, there were 23.4% of nausea and vomitting and 9.7% of dizziness in group B,7. In relation of the diagnostic methods, the positive rate of culdocentesis in group B was lower than the rate in group A. Diagnostic laparoscopy was done in 5.6% of group A and 14% of group B. The detection rate of adnexal mass and fluid collection in the pelvic cavity was higher in group B than in group A on the ultrasonographic examination. 8. Initial hemoglobin value of 10.1mg/dl or more was 70.9% in group A and 73.2% in group B. The value of 8.0gm/dl or less was 6.4% in group A and 7.0% of group B, respectively. Initial systolic pressure of 110mmHg or more was 74.6% in group A and 66.6% in group B. The systolic pressure of 90mmHg or less was 3.6% in group A and 8.3% in group B.9. The conceptus was almost implantd in the fallopian tube. The ampullary portion was the most common site of ectopic implantation in both groups. 10. Intraabdominal hemorrhage of 500ml or less in amount was 52.4% in group A and 61.1% in group B, individually. However transfusion was not given in 55.6% of group A and in 71.0% of group B. 11. In the therapeutic modalities, laparotomy was performed in 96.8% of group A and in 82.8% of group B, respectively. The pelviscopic operation was done in 2.4% of group A and in 22.3% of group B. In conclusion, ectopic pregnancy was diagnosed increasingly prior to the onset of the hypovolemic symptoms according to developement of high-resolution ultrasonogram, diagnostic laparoscopy and beta-hCG test, therefore the use of minimally invasive techniques in the management of ectopic pregnancy was increasing.

About 40% of patients with rheumatoid arthritis show extra-articular manifestations. The presence of rheumatoid nodules is the most common extra-articular manifestation, which is commonly seen at pressure points. Rheumatoid nodules can also occur in the lung, heart, and larynx. Laryngeal rheumatoid nodules may lead to phonatory and respiratory symptoms and can be mistaken for other medical conditions such as inflammation and neoplasm. Recently, we encountered a case of rheumatoid nodules involving the larynx in a 56-year-old woman with a 3-year history of rheumatoid arthritis and Sjogren's syndrome. Herein, we report the case with a review of the literature.

Severe morphologic changes in the central nervous system(CNS) have been recognized in aucte carbon monoxide(CO) poisoning. These have been usually located in globus palIidus, hippocarnpus, substantia nigra, cerebral white matter, cortical gray mattr, and cerebellum. It is well known that lesions in the CNS are shown both in the globus pallidus and cerebral white matter on neuroradiologic studies using CT or MRI. However we recently experienced two patients of aucte CO poisoning with residual neurologic sequelae, showing the bilateral lesions in the globus pallidus and substantia nigra on MRI performed 10 to 11 days after acute CO poisoning. Experimental studies were performed to investigate the correlation between the physlological data, such as duratlon of CO exposure, change of blood pressure, and termmal carboxyhemoglobin (HbCO) concentration in the blood, and the severities of pallidal and nigral lesions in acute CO exposured cats. Twelve mature cats, weighing 2.7-3.8kg, were exposured to 0.3% CO gas for 95-215 min. using artificial ventilation. The systemic blood pressure and electrocardiograrn were monitored continuously during CO exposure. HbCO concentration in the blood was analyzed immediatelly when CO exposure was terrninated. One to 12 days after CO poisoning, animals were killed and the brain was examined morphologically. Then the correlation between the physiological data and the severities of ischemic change in the globus pallidus and substantia nigra was examined. The results were summerized as follows; 1. The duration of CO ex.posure was ranged from 95 to 215 minutes, and the degree of BP drop from 14 to 76%. There were various hnds of abnorrnalities, such as cardiac arrhythmia and ischemic pattem on EKG, and terrninal HbCO concentration in the blood was ranged from 36 to 79.3%. 2. Morphologically, there was focal necrosis with intense infiltration of macrophages in the globus pallidus of a cat. In the globus pallidus of the remaining 11 cats, the severity of ischemic change was 27.3 to 95.6%.

We report here a case of vascular Behcet's disease. 32-year-old young woman who suffered from chest pain was diagnosed with acute myocardial infarction four years before admission. At that time she manifested symtoms of Behcet's disease, such as oral ulcers, genital ulcers, multiple arthralgia, and a peculiar hyperirritability reaction to needle puncture. At this time she was admitted due to acute chest pain and intermittent abdominal pain. The diagnosis of an acute anteroseptal myocardial infarction was made on the basis of the electrocardiography findings. Cardiac catheterization revealed segmental stenosis up to 95% at the mid-left anterior descending artery without aneurysm formation at other coronary trees and there were no atherosclerotic changes. Coronary stent was inserted in the lesion. Abdominal CT showed inferior vena cava and right hepatic vein obstruction, which supports the diagnosis of Budd-Chiari syndrome. Our case demonstrated the followings which are not common to vasculo-Behcet disease; 1) initial clinicopathologic manifestations at the coronary artery, 2) abrupt total occlusion with clear cut lesion at left anterior descending artery, 3) recurrent myocardial infarctions, 4) Budd-Chiari syndrome, 5) combined superior mesenteric artery, inferior mesenteric artery and celiac trunk obstruction. Among the systemic manifestation of Behect's disease, cardiac involvement is very rare but should be considered as one of the most important features that influences the prognosis.
