Dyke-Davidoff-Masson syndrome is a rare clinical syndrome consisting of hemiatrophy of cerebral hemisphere, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. Its clinical manifestations are hemiparesis, several types of seizure, mental retardation and other neurologic deficits. We experienced a case of Dyke-Davidoff-Masson syndrome in a four months old boy who visited to our department due to right side upper extremity weakness and infantile spasm. The brain magnetic resonance imaging showed marked hemiatrophy of left cerebral hemisphere and enlargement of left lateral ventricle. So with the review of literatures, we report a case of Dyke-Davidoff-Masson syndrome with infantile spasm.

PURPOSE: To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. RESULTS: The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17. 4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). CONCLUSION: The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraaortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type.

Among total 108 cases of biopsy-proven fibroadenomas of the breast, which obtained from the files of the Asan Medical Center during one year period from October 1998 to September 1999, 23 cases cytologically diagnosed as high risk group were reviewed to retrieve the mis-leading factors. Initial cytologic diagnoses of 23 cases were proliferative breast lesion with atypia(high risk) in 21 cases(91.3%) and papillary neoplasm in 2 cases(8.7%). When we reanalysed 23 cases by Masood scoring system, they were classified as one non-proliferative breast lesion(4.3%), 16 proliferative breast lesions without atypia (69.6%), and 6 proliferative breast lesions with atypia(26.1%). None were subject to the category of carcinoma. Cytologic features leading to the overdiagnosis of high grade epithelial lesions were as follows; cellular dissociation without nuclear atypia, nuclear pleomorphism, anisonucleosis, and occasional macronucleoli without nuclear enlargement, lack of myxoid stroma, and few naked stromal cells. To avoid cytologic overdiagnosis of fibroadenoma, mild to moderate nuclear pleomorphism without nuclear enlargement, and cellular dissociation without nuclear atypia should not be regarded as criteria of high risk group.

The prefabrication by vascular induction into random patterned flaps is a method creating axial donor flap by implantation of nourishing pedicles prior to harvesting random patterned flaps. The purpose of this study was to evaluate the viability of a thin prefabricated flap prepared by the subdermal implantation of fasciovascular pedicles without subcutaneous tissue or muscular layer, by comparing with the prefabrication by the subpanniculus carnosus implantation of vascular pedicles, which is well known to a predictable survival rate by many authors. In the left abdomen of 40 Sprague-Dawley rats, the fasciovascular pedicles were implanted in the subdermal layer in group I(n=20) and sub panniculus carnosus layer in group II(n=20), respectively. 5 weeks later, 4 x 6 cm sized abdominal flap was elevated with implanted vascular pedicle as an island and reposed immediately. At the same time, in the right abdomen, conventional island flap was elevated and reposed. After 3 days later, the evaluation of the survival area was carried out in each side, in both groups. The mean proportions of the survival areas in group I were 74.2 and 91.8% in the prefabricated and conventional flap, respectively. And those in group II were 76.4 and 91.2% in the prefabricated and conventional flap, respectively. These results showed that there is no difference in the proportion of survival area between two types of prefabrication. In conclusion, it is possible to prefabricate a thin axial-patterned fascioutaneous flap without subcutaneous tissue and the viability of this prefabricated flap is reliable as much as that of other prefabricated flaps having subcutaneous or muscular tissue.

Transcatheter arterial chemoembolization(TACE) is an imperative method for the managment of inoperable hepatocellular carcinoma(HCC). It is well known that primary HCC frequently invades the portal venous system and forms a tumor thrombus obstructing the portal blood flow which makes unfavorable prognosis of patiebt. We retrospetively reviewed 58 patients who reveived TACE(minimum 3 times) of HCC invading into portal venous system. Group 1(n=29) which showed peripheral portal vein invasion had better clinical and laboratory response. Group 2(n=17) which showed first order portal branch invasion had similar response to Group 3(n=12), which had main portal invasion. Group 1 showed no difference in survival time between TAC and TACE, but, in Group 2 and 3, emboliation with chemotherapy made longer survival than chemotherapy only. Clinical level of AFP was meaningful in Group 1 and 2 as decreasing value. Our results provides that careful selection of TACE and case by case Coil/Gelfoam embolization can improve the mean survival and clinical response when HCC evidently invades portal venous system.
