Friction melanosis is frequently developed in thin, young woman, on thc covered skin of spinc, rib, elbow, knee and tibia. These lesions range from brown to rcddish-brown in color, appear in either band shapes or reticular patterns, and exhibit no overt syrnptoms. They do not show any inflamatory changes, and the skin remains smooth. According to histopathological findings, the main changcs arc perivascular melanophages on the papillary derrnis and upper dermis, and also increased melanin granules on the basal layer. The following case concern a relatively thin 20-year-o1d female patient. She had a syrwptoniless brown color changcs above the ribs of back, growing in dircction of the ribs for a period of three years. This change was band shaped, but there were no signs of inflammatory reaction, leaving the skin smooth. A biopsy was performed on the relevant tissue, and clinical-histopathological analysis was resulting in diagnosis of friction melanosis.

A 33-year-old man had multiple, dome shaped, pin-head sized, hard papules on the center of face and pigeon's egg sized hard tumors on the left upper arm and the trunk. The histopathological findings of the skin biopsy specimens from face and left upper arm showed tumor islands composed of basophilic cells of the same sppearance as basalioma cells, arranged in a lacelike and solid aggregates, without horn cysts.

Hemangioma are not rare tumor, they are found in almost all the vascular structures of the body. They are fairly common in the akeletal muscles. There Is no unanimity of opinion concerning the etlology and pathogenesis of hemangioma. It Is most llkely, however, that hemangioma are congenital in origin. The authors have experienced unusual huge skeletal hemangioma occurred in forearm and hand in infant. These huge hemangioma in infant ls very difficult to excise completely with the conventional methods. But we have obtained the excellent result by using recently advanced meticulous microsurgical technique.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

An arteriovenous fistula may be defined as a vascular abnormality in which there are one or more direct or indirect communication between an artery and a vein without any intervening capillary bed. Largely, such fistulas are divided into two groups-acquired (traumatic) or congenital in origin. There is a general agreement that congenital A-V fistula results from a failure in differentiation of the common embryonic anlage into true artery and vein. The authors have experienced a case of congenital A-V fistula formed in the 4th finger of the left hand. Such fistula is very difficult to excise completely with the conventional method. But we have obtained the excellent result by utilizing advanced meticulous microsurgical technique in excision.

In view of the problems with infection, traditional orthopedic teaching has held that the use of metalic fixation in open fractures is contraindicated. But the bone shortening and internal fixation of amputated limb is a principle for replantation. The authors experienced 23 patients of replanted limbs including femur, tibia, humerus, radius and ulnar among total 142 replantations and also analysed them in the respect of the relationship among soft tissue injury, fixatives, bone union and infection rate from February, 1975 to July, 1981 in this department. The rate of delayed union, nonunion and infection were 22.6%, 6.5% and 25.8% respectively. It seems that the union process of bone in replanted limbs is similar to that of the open fracture and also rigid internal fixation is the most useful for bony union.

A case of the brain death confirmed by isotope angiogrphy is described. Isotope angiography is a simple and noninvasive technic compared to carotid angiography, and is recommended as a reliable test for the diagnosis of brain death.

The authors present a case of posterior fossa arachnoid cyst associated with syringomyelia. A 58-year-old woman was admitted to our hospital due to progressive headache, gait disturbance, and pain at the left upper extremity. Magnetic resonance(MR) image showed a huge retrocerebellar arachnoid cyst associated with syringomyelia from the second to the sixth cervical vertebral level. After decompression of the posterior fossa including removal of posterior lip of foramen magnum and lamina of the atlas and fenestration between arachnoid cyst and subarachnoid space, the patient's symptoms were improved and the arachnoid cyst and syrinx were shrunken on follow-up MR imaging. The authors discuss the pathogenesis of the syringomyelia associated with a huge posterior fossa arachnoid cyst and the management option.
