The treatment of scar contracture has a relatively long history in the department of plastic surgery. Flap surgery, including Z-plasty and skin graft has been a common surgical modality for the treatment of scar contracture. However, the 'deficiency' of the tissue is basically responsible for the limitations of this treatment. The concept of tissue expansion has contributed to the solution of tissue deficiency and thus tissue expansion is currently widely used for various purposes in plastic and reconstructive surgery. Nevertheless, tissue expansion has not yet clearly solved the problems in cases of seven deficiency of surrounding normal tissues, or in cases of multiple and diffuse scar contracture. We have tried to 'expand the scar tissue' to overcome these limitations. The authors 'several decades of experience in tissue expansion has taught us to find the usefulness of incidentally expanded scar tissues. Thirty-one patients with scar contracture urderwent expansion of surrounding normal and/or scar tissues, including 5 cases of pure scar tissue expansion. The postoperative results were satisfactory with a minimal complication rate. In conclusion, scar tissue expansion was usefully applicable for the scar contracture with no surrounding normal tissues. Scar tissue could be expanded safely and sufficiently, designed to various flaps, and the flap survival was reasonable. The functional and aesthetic quality of the scar tissue seems to improve following tissue expansion. In addition, meticulous planning is essential from the initial operation, including the area of expander insertion, flap design considering the aesthetic unit and functional aspect.

PURPOSE: To evaluate the radiologic manifestations of the rectal leiomyosarcoma. MATERIALS AND METHODS: We reviewed CT and barium study of 2 cases of rectal leiomyosarcoma, which were operated and pathologically proved. RESULTS: In both cases colon studies showed a huge smooth marginated filling defect in the rectum. Precontrast CT scans showed a well-circumscribed, slightly Iobulated, inhomogeneous mass without calcification. Postcontrast scans showed minimal enhancement with internal low-density areas. In pathologic specimens there were large areas of necrosis and hemorrhage in the masses. Pericolic fat infiltration, lymph node metastasis, or distant metastasis were not detected. CONCLUSION: Leiomyosarcoma is rarely developed in the rectum, but general radiologic findings are similar to that of other part of the gastrointestinal tracts except for the tendency of intraluminal growth due to narrow pelvic space.

BACKGROUND: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament. MATERIALS AND METHODS: Twenty two patient who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function. RESULTS: Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (p<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group. 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray. CONCLUSION: Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.

BACKGROUND: Photodynamic therapy(PDT) is a type of photochemotherapy that is designed to kill targeted tumor cells. OBJECTIVE: The Clinical effects of PDT were analysed for response rates, post-treatment healing and adverse effects on several cutaneous carcinoma in situ. METHOD: PDT with topical 5-aminolevulinic acid-based irradiation of corresponding 630+5nm light was performed in 6 carcinoma in situ patients who had actinic keratosis, Bowen' disease or cutaneous squamous cell carcinoma. RESULT: In all patients the clinical results were exellent with respect to initial complete responses and cosmetic outcome. CONCLUSION: PDT might be chosen as a first line treament for cutaneous carcimoma in situ.
