Mixed tumor of the skin (chondroid syringoma) is a rare benign tumor composed of epithelial elements intermingled with myxoid or cartilagenous stroma which is not separated by basement membrane. It had been believed to originate from the eccrine gland but recently, it was described to be of apocrine gland origin in case of showing apparent apocrine secretion. We report on a 63-year-old man with a tumor on the right upper eyelid showing typical microscopic features of mixed tumor of the skin. Many apocrine decapitation secretions were seen in tubular structures and follicular differentiations were also seen, which represents the common origin of folliculo-sebaceous-apocrine unit.

Blue nevus is a benign melanocytic neoplasm and represents itself usually as a solitary blue or blue-black papule. It rarely occurs as multiple lesions grouped in a circumscribed area. How-ever, non-grouped disseminated blue nevi are exceedingly rare. We report a patient with acquired multiple blue nevi that was distributed over the entire body discretely and showed an increase in the number of the nevi without any causal factors.

Mesenteric fibromatosis is a rare nonmetastasizing fi brous tumor, characterized by fibroblastic proliferation without evidence of inflammatory response or definite neoplasia. It appears at any age, but mainly in the second to fifth decades as incidence of two to four desmoid tu mor cases per 1 million people per annum. It is pseudoen capsulated and locally invasive and has a tendency to recur, but metastases are rare. It is more frequent with Gardner's syndrome(adenomatosis coli) in which 50% of them will appear as mesenteric fibromatosis. Trauma, especially that of previous surgery, has been associated with the subsequent development of desmoid tumor. The treatment of choice is a wide margin resection of the tumor. we experienced a case of mesenteric fibromatosis without Gardner's syndrome 2 years after appendectomy in a 31-year old man and recurred at 21 months after resection and report with a review of literatures. 6

An endobronchial metastasis is defined as a subsegmental or a more proximal central bronchial metastasis of a nonpulmonary neoplasm in the bronchoscopically visible range. However, the frequencies of endobronchial metastasis range from 2 to 50% of pulmonary metastases from extrathoracic neoplasms by a different difinition of an endobronchial metastasis. Primary neoplasms of an endobronchial metastasis including breast cancer, colon cancer, renal cell carcinoma, and ovarian cancer are relatively common. However, an endobronchial metastasis arising from thyroid cancer, parotid gland tumor, bone tumor, bladder cancer, and stomach cancer has only rarely been reported in the literature. Here we report a case of an endobrochial metastases from a hepatocellular carcinoma

PURPOSE: To evaluate the usefulness of echo-planar FLAIR imaging in various cerebral lesions as compared with fast FLAIR imaging. MATERIALS AND METHODS: We obtained consecutive fast FLAIR and echo-planar FLAIR images in 33patients in whom MR imaging had revealed ischemic infarction (n=11), acute infarction (n=5), brain tumor (n=3), other conditions (n=3) or no abnormality (n=11). On both sets of images, percentage contrast and contrast to noise ratio (CNR) were calculated for white matter-gray matter and white matter-lesion. RESILTS: White matter-gray matter percentage contrast and CNR were lower on echo-planar FLAIR imaging than on fast FLAIR imaging (percentage contrast, 19 +/- 2 % vs 28 +/- 3 %, CNR, 2.77 +/- 0. 5 vs 4.86 +/- 0.7). White matter-lesion percentage contrast on echo-planar FLAIR imaging was similar to or greater than that on fast FLAIR imaging; 75 +/- 12 % vs 45 +/- 11 % in ischemic infarction, 80 +/- 12 % vs 78 +/- 11% in acute infarction, and 121 +/- 25 % vs 102 +/- 15 % for tumors. White matter-lesion CNR was similar on both sets of images: 8.3 +/- 0.9 vs 7.9 +/- 0.8 in ischemic infarction, 11 +/- 1.5 vs 9.5 +/- 1.2 in acute infarction, and 24 +/- 4 vs 27 +/- 3 for tumors. Due to high susceptibility to magnetization, echo-planar FLAIR imaging showed image degradation at the interface of the paranasal sinus and adjacent to the temporal bone. CONCLUSION: Echo-planar FLAIR imaging may be a useful pulse sequence in the diagnosis of various cerebral lesions.

Gastric carcinogenesis has been studied in various aspects. Helicobacter pylori (Hp) infection and mutation of the p53 tumor suppressor gene have recently been argued to be important factors of gastric carcinogenesis. There have been many studies to determine the precise mechanism of how Hp is related to gastric cancer, but it is so far still unknown. We studied the relationship of Hp infection and p53 overexpression and tried to discover some significance in clinicopathologic factors such as age, sex, stage, site, differentiation and gross morphology. Ninety-six patients who were diagnosed with gastric cancer at Severance Hospital, Yonsei University Medical College from November 1995 to March 1996, and 96 control patients of non-ulcer dyspepsia (NUD) were studied by endoscopic biopsy of normal gastric tissue and cancer tissue. They also underwent the CLO (Delta West, Melbourne, Western Australia) test for Hp positivity and p53 immunohistochemical stain for p53 positivity. These data were analyzed for comparison with the clinicopathologic characteristics of gastric cancers. In conclusion, the differentiated group cancer had a significantly high Hp positivity and p53 positivity. There is a possibility that Hp infection and p53 tumor suppressor gene mutation might be significantly related in the gastric carcinogenic process of well- and moderately-differentiated adenocarcinomas, but further study is necessary to determine more direct clues on the carcinogenic roles of these factors.

We have experienced 19 patients of the cerebral arteriovenous malformation with subarachnoid hemorrhage, who were admitted to the Presbyterian Hospital, Daegu from January 1966 to July 1968, and to the Catholic Medical Center, Seoul from August 1968 to August 1971. All of the patients, who have the cerebral arteriovenous malformation, were proved by cerebral angiography. Since the site of lesions were considered to have close relation to the neurologic deficit and the result of surgery, various analysis of the clinical manifestations and the cerebral angiographic findings were attempted. Of the 19 patients, surgery was performed on 12 patients and its results were analyzed correlating to various types of surgical procedure. Following are the results. 1. From January 1966 to August 1971, there were 100 cases of cerebral vascular anomalies which were proved by cerebral angiography. Among the 100 cases, there were 71 intracranial aneurysms, 19 cerebral arteriovenous malformations, one cavernous angioma, 2 telangiectasis, 5 cerebral rete mirabile, and s Sturge Weber-Dimitris disease. The ratio of arteriovenous malformatons to aneurysms was 1: 3.7. 2. Age distribution of the bleeding arteriovenous malformations was ranged from 8 to 54, and 42 per cent of them were in the third decade. 73 percent of the group had bleeding from the cerebral arteriovenous malformation before the age of 40. The ratio of male to female was 1.9:1. 3. The parietal region was most commonly involved by the malformations. There were 8 parietal lesion, 4 temoroparietal lesions, one temporal lesion, one occipital lesion, and one tela chorioidea lesion. Simultaneous involvement of the both hemispheres occurred in one case. In lesions involving the cerebral hemisphere, there was a predominance of the left side. 4. In the past history, convulsive seizure was recorded in two cases and recurrent hemorrhages were reported in two. One patient was recorded to have suffered fourth hemorrhage and the other have sufferd third hemorrhge. 5. Meningeal irritation signs were most frequently observed in bleeding arteriovenous malformations. The incidence of weakness of extremities was higher in lesions involving the parietal area. Unconsciousness was occurred in 6 patients at the onset of symptom, of which transient loss of consciousness was seen in 3 patients. Transient hypertension at the onset was observed in two patients. 6. The feeding arteries of the malformations were most frequently seen from the middle cerebral artery and the draining veins from the malformations were into the superior sagittal sinus and internal cerebral vein in many cases. It was evident that the carotid artery of the sites of arteriovenous malformations was markedly dilated in 5 patients. 7. Ligation of the vessels feeding the arteriovenous malformations was carried out in 8 patients. One patient had neurologic deficit after the operation. Evacuation of intracerebral hematoma, resection of the anomaly or carotid ligation were carried out in 4 patients. Of the 12 patients who underwent various types of surgery, there was one death after evacuation of a large intracereral hematoma. 8. In our opinion, the ligation of feeding artery a choice of procedure to reduce the incidence of rebleeding, if the resection of the lesion was considered to have operative risk by the location of malformations.

The main symptoms of adult isthmic spondylolisthesis are frequently low back pain and radicular leg pain. Laminectomy and posterolateral fusion is somtimes unsuccessful because nerve roots are compressed by fibrocartilagenous tissue at pars defect, degenerated disc and slipped bony edge. The patients need complete neural decompression, reduction of slipping and stable fixation. We have operated 22 patients with PLIF using carbon cage and transpedicular screw fixation after posterior decompression by Gill's operation and complete removal of intervertebral disc. We studied the patients postoperatively to evaluate the symptomatic improvement, reduction rate of slipping and stability of lumbar spine. Twenty-two patients were operated from April, 1996 to June, 1997. Mean age was 46, ranging from 35 to 68. Mean follow-up duration was thirteen months. The levels of operarion were 9 at L4-5 and 9 at L5-S1, 4 at both levels. Mean preoprative slip was 17.2%, which was reduced to 11.3% postoperatively. Nineteen patients(86%) were satisfied with the result of operation. The fusion rate of PLIF was 86%. There was no breakage of instrumentation or postoperative instability. We consider that PLIF and transpedicular screw fixation for adult isthmic spondylolisthesis with radicular leg pain is a good methods to obtain complete neural decompression, reduction of slip and stable lumbar fixation.
