Unknown primary melanoma shows only metastatic malignant malanoma without obvious primary tumor. These unusual instances of unknown primary melanoma have reported incidences of 1.0~8.7%. This 51 year old patient had many intra-abdominal and mesenteric masses without visible primary tumor. The most commonly accepted explanation for unknown primary melanoma is spontaneous regression of a primary skin lesion.

Bowing of one or both bones of the forearm in children following acute trauma was first recognized by Borden in 1974. Since then, a total of 30 cases have been reported in the English literature. The injury is a result of an acute plastic deformation of the tubular bones due to mainly a longitudinal compression force, and is charactcrized by: 1) a broad fixed curvature of the entire bone, 2) absence of periosteal new bone formation on later roentgenograms, and 3) partial correction of the curvature through cortical remodeling in young children. In this paper, three cases of traumatic bowing of the tubular bone in children are presented: one traumatic bowing of both forearm bones in 15 years old girl and two traumatic bowing of fibulae in combination with fractures of diaphysis of the tibiae of the same legs in 6 years old girl and 6 years old boy respectively. Manipulative reduction for the bowing of the both forearm bones corrected remarkably the plastic curvature, whereas manipulation for the bent fibulae with fractures of the tibiae failed to reduce the curvature, causing no delay in fracturt healing. These three cases are of special interest from two points of view. The first case was caused by tangential force instead of a longitudinal one and was associated with ulnar nerve paralysis which has eventually been recovered. The other two cases occurred in the lower leg in which plastic deformation, according to previous report, would not develop because of the lack of intrinsic curvature of the tibia and fibula.

BACKGROUND & OBJECTIVE: Recent studies suggest that anticoagulation, or antiplatelet therapy is safe and effective for the prevention of cardiogenic embolic stroke. However it has not been studied in Korea how the patients with cardioembolic source were managed in practice for the prevention of stroke. This study was done to assess the current status of primary and secondary prevention of cardioembolic stroke. METHODS: Retrospective study was undertaken in 124 patients with cardiogenic embolic stroke, following items were examined, previous anticoagulation or antiplatelet therapy, previous stroke, Insight of the heart disease, and International Normalize Ratio(INR) value on arrival at the hospital. RESULTS: In 124 patients cardioembolic sources were constituted of non-valvular atrial fibrillation (NVAF) in 54, rheumatic heart disease In 40, prosthetic cardiac valve In 14, dilated cardiomyopathy(D-CMP) in 6, left ventricular akinetic segment in 7(including 3 cases of LV thrombi), recent myocardial infarction in 3. In 93 patients with no previous stroke, 44 patients had regular medical follow-up because of his/her cardiac problems and primary prevention of stroke was made only in 12 (27%) patients (8 on anticoagulation and 4 on antiplatelet therapy). The rate of primary prevention varied according to the type of cardioembolic source; 100% with mechanical prosthetic valve, 33.3% with valvular atrial fibrillation, 6.7% with NVAF, and none with D-CMP and bioprosthetic valve. Previous stroke was found in 31 patients, among whom 24 had been followed regularly. Twenty patients(83%) were under secondary prevention of cardioembolic stroke (anticoagulation in 11 and antiplatelet agents in 9). Among 19 patients who developed stroke in spite of anticoagulation, INR values were lower than 1.5 in 12(63%), between 1.5 and 2.0 in 5(26%), and above 2.0 in 2(11%). CONCLUSION: Our results suggest that cardioembolic strokes have not been prevented properly. Many physicians seem to be reluctant to anticoagulate their patients with cardioembolic source, and even with anticoaguation the dosage is frequently insufficient to prevent stroke.

We decribe the CT findings in a case of mediastinal hemangioma. Precontrast enhanced CT demonstrated a homogeneous soft tissue mass with weveral nodular calcifications indicating phleboliths. Contrast enhanced CT revealed some areas of enhancement similar to that of adjacent vascular structures. Hemangiomas of the mediastinum, although rare, should be included in the differential diagnosis of enhancing mediastinal masses.

Melorheostosis is a rare entity while causes pain and stiffness in a limb and has an unknown etiology. It is characterized by roentgenographic appearance of melting wax dripping down one side of a candle along the major axis of long bone. The present case represents a melorheostosis of the left tibia accompanied by synovial chondromatosis in the left knee. Good result was obtained by arthrotomy of the left knee and removal of the bony masses in the joint.
