In 1983, Nora et. al. reperted 35 cases of bizarre parosteal osteochodromatous proliferations of the hands and feet. All lesions occured on proximal phalanges, metatarsals, or metacarpals. The gross appearance was typically that of a small osteochondroma. Radiologically, the proliferations lacked both central continuity of the tumor with the underlying osseus medulla and flaring of the adjacent cortices. Histologically, the lesion exhibited marked proliferative activity, irregular bohy cartilaginous interface, and enlarged, bizarre, and binucleate chondrocyte. The authors experienced a case of bizarre parosteal osteochondromatous proliferation of the right foot in a 61 year-old female which arised from the proximal phalanges of second toe, hostologic and radiologic findings were consistent with the bizarre parosteal osteochondromatous proliferation. The mass was treated by excision, and neither recurrence, nor malignant change was observed up to one year follow-up period.

Longitudinal growth acceleration of the femoral shaft after fracture in children has been recognized since the late nineteenth century, Orthopaedic surgeons have attempted to compensate for the leg length discrepancy by allowing union to occur with some degree of shortening, but logitudinal overgrowth following fractures of the tibial shaft in children has been rarely studied. Thirty-one children, treated for fracture of the shaft of tibia, were studied prospectively to assess the consequent increase in longitudinal growth of the tibia. The material presented in this paper is the result of the study of thirty-one children with fractured tibia who were treated in the Department of Orthopaedic Surgery of Kangnam Sacred Heart Hospital of Hallym University, since 1986 October, the age of the child varied from 3 years to 13 years, these cases have been followed from 30 months to 40 months. We have made a radiologic study of fracture of the tibial shaft with a view to analysing the results according to a number of factors, including the sex and the type, site and degree of overriding of fracture, and method of treatment, and then the degree of overgrowth was compared with unaffected side. 1. The average tibial overgrowth following tibial shaft fracture is 7mm. 2. Growth of the femur was not affected by the tibial fracture.

PURPOSE: The purposes of this study were to analyze the MR findings of medulloblastoma, and to evaluate the subarachnoid dissemination and the significance of contrast enhanced MR of brain and spine for tumor.. MATERIALS AND METHODS: The preoperative brain MR studies of 18 patients (9 males, 9 females;mean age, 9.4 years) with surgically proved medulloblastomas were retrospectively reviewed to characterize these neoplasms with regard to their location, size, MR signal intensity, appearance after contrast enhancement, presence of cyst and necrosis, subarachnoid dissemination, and other associated findings. In 14 patients postoperative spine MR studies were evaluated for staging and therapeutic planning. RESULTS: The most frequent location of medulloblastoma was the inferior vermis and the mean tumor size was 4.1 x 3.6 x 3.9 cm. On Tl-weighted image, medulloblastomas generally had low to intermediate signal, predominantly hypointense relative to white matter. On T2-weighted image, medulloblastomas showed modetately high signal, hyperintense relative to white matter. Inhomogeneous contrast enhancement was demonstrated in 13 patients(72.2%) after injection of gadopentetate dimeglumine(Gadolinium). Cyst and necrosis within the tumor were visualized in 15 patients(83.3%). Subarachnoid disseminations of medulloblastomas were noted in 11 patients(61.1%), of which 6 demonstrated intracranial and 2 intraspinal dissemination. Three had both intracranial and intraspinal dissemination. In nine cases with intracranial lesions, there were intraparenchymal mass formation(7), subarachnoid nodules(5), infundibular lesions(2) and diffuse gyral enhancement(I). In five cases with intraspinal lesions, there were extramedullary intradural small nodules(3), central canal nodules(2), intradural masses(I)and fine nodular and sheet-like leptomeningeal enhancement(1). Other associated findings included intratumoral hemorrhage(11.1%), per/tumoral edema(44.4%), tonsillar herniation(44.4%), hydrocephalus(88.9%) and calcification(44.4%). CONCLUSION: Medulloblastomas revealed low to intermediate signal intensity on Tl-weighted image and intermediate to moderately high signal intensity on T2-weighted image, relative to cerebellar white matter. Medulloblastomas were solid tumors with cystic necrosis, which showed inhomogeneous enhancement and subarachnoid disseminations to the intracranial and intraspinal spaces after Gd-DTPA enhancement. Gd-enhanced MR of brain and spine was an useful diagnostic modality in preoperative diagnosis and in staging of postoperative cases of medulloblastomas, which was superior to postcontrast CT or precontrast MR.

PURPOSE: To analyze angiearchitecture of arteriovenous malformations(AV malformation) in order to clarify the angiegraphic risk factors for intracerebral hemorrhage and other nonhemorrhagic symptoms. MATERIALS AND METHODS: Eighty-five patients with angiegraphically-proved brain arteriovenous malformation were included in this study. Retrospective review of clinical history and angiography was done. Topographic analysis and evaluation of 17 angiearchitectural characteristics were conducted. RESULTS: Deep-seated and cortico-callosal type, small nidus size, intranidal pouch, one draining vein, deep venous drainage only venous stenosis and venous aneurysm were the most discriminating or predictive characteristics of hemorrhage in brain arteriovenous malformation. And those with large nidus size, dural supply and venous hypertension were correlated with nonhemorrhagic symptoms such as seizure, headache and neurologic deficit. CONCLUSION: Detailed analysis of the angiearchitecture of brain arteriovenous malformations is needed to identify the features that are correlated with prognostic implications for the treatment of patients with ^V malformations.

Superficial migratory thrombophlebitis (SMT) represents multiple, tender, often cordlike nodules, usuallyion the legs but occationally on the arms. In some instances the nodules slowly migrate along the course of a vein. It can occur in association with carcinoma of internal organ or other diseases but also idiopathically. In 1865 Trousseau first wrote about that patients who have carcinoma involving an internal organ are prone to develop thrombophlebitis in one or more superficial veins so he drew attention to the fact that thrombophlebitis may be a first presenting sign of carcinomatosis. In fact, it is not uncommon for the ordinary thrombotic lesions to be observed several months or even a year before the carcinoma would otherwise diagnosed. So the clinical manifestation of SMT may be very important dermatologic finding to find hidden cancer of visceral organ. We present two cases of SMT, first case is a 25-year-old male patient who had multiple, tender nodules on both lower extremities and second case is 32-year-old male patient who had multiple, tender, linear, often cordlike nodules along the inner aspect of right lower extremity. Because we could not find any internal carcinoma or other diseas esexcept histories of hepatitis, we regard them as idiopathic type, but continuous follow up observation must be needed under the importance of possible presence of internal carcinoma.

Herpes Gestationis is a rare polymorphous, vesiculobullous disease of pregnancy and puerperium. It is characterized by rapidly progressive skin eruption heraled initially by severe generalized pruritus. Erythematous papules and urticaria like plaques rapidly appear followed by grouped, tense, vesiculobullous eruptions. A 23 year-old pregnant woman was admitted to our departrnent of dermatology hecause of erythematous patches with pruritic vesiculobullous and pustular eruption on the whole body since third week of conception, Biopsy specimen of bullous skin lesion showed spongiosis of epidermal cells, mild necrosis of basal cells, subepidermal bulla, edema, of papillary derrnis and perivascular infiltration of inflammatory cells. Ultrastructural findings showed mild necrosis of basal cells, bulla above or below basement membrane zone and partial separation of basal larnina. Direct immunofluorescences of bullous lesion and normal appearing skin demonstrated deposition of IgG in linear pattern along basement rnembra,ne zone. After treatment with systemic corticosteroid and antihistamin, the lesions were cleared, leaving residual hyperpigmentation, and she delivered normal female baby.
