Immunohistochemical staining was performed in 20 skin granulomas of 16 patients with leprosy using antisera against lysozyme and S-100 protein. In lepromatous leprosy, lysozyme positive cells and S-100 protein positive cells were rarely found in the dermis. However, the histoid leprosy specimen had large numbers of lysozyrne positive cells and S-100 protein positive cells in granuloma. In borderline group, lysozyme positive cells and S-l00 protein positive cells were found in the dermis. S-100 protein positive cells were diffusely distributed throughuut the granuloma in borderline lepromatous leprosy, while they were often found in lymphocytic mantle in borderline tuberculoid leprosy. In tuberculoid leprosy, lysozymal staining was encouritered in epitheloid cells and giant cells, but S-100 protein positive cells were predominantly found encircling granuloma. In the epidermis, great numbers of S-l00 protein positive cells were found in tuberculoid leprosy than in lepromatous leprosy.

The congenital ball-and-socket ankle joint is a rare condition and is associated with congenital shortening of the lower extrimity and various skeletal abnormalities of the foot. This disease entity was reported in the German literature by Politzer in 1931 and in the English literature by Lamb in 1958. Several series have been reported since, suggesting that the condition may not be as rare as generally thought. This case is, to our knowledge, the first reported in this country.

Radical cystectomy is the most common and effective treatment modality for invasive bladder cancer. However, in case of the elderly patient its application accompanies anxieties over the possible mortality and complications. We purposed to analyze the postoperative mortality and early complication of the elderly patients compared to those of non-elderly patients. We reviewed retrospectively the medical records of 27 elderly patients, over 70 years of age and 61 non-elderly patients, under 69 years of age who were not at high risk anesthesiologically and underwent radical cystectomies with ileal conduits for invasive bladder cancers during last 11 years. We compared mortality, early complications, and postoperative hospital days between two groups. There was no death related to operation in elderly group, but one of the non-elderly group died of sepsis and DIC(disseminated intravascular coagulation) postoperatively Overall early complications were significantly higher in elderly group(P=0.013). But the major complications that were life threatening or required reoperation revealed no significant difference between two groups. There was no significant difference in postoperative hospital days(16.8 days in elderly group, 16.1 days in non-elderly group) between two groups. In conclusion, radical cystectomy can be performed as an effective and safe modality for the treatment of invasive bladder cancer even in elderly patients if only they are not at high risk anesthesiologically.

8.Reconstruction of the Tissue Defects of Extremities with Anterolateral Thigh Free Flap.

For the reconstruction of various tissue defects, free tissue transfer has been a very popular method in recent years. A large thin flap is required for aesthetic and functional resurfacing of the extremity defects. As a result, anterolateral thigh free flap has been thought to be useful in reconstructing soft tissue defects requiring thin flap coverage of extremities. The anterolateral thigh flap is a septocutaneous flap based on the septocutaneous or musculocutaneous perforators of the lateral femoral circumflex system. It supplies a large area of skin on the anterolateral aspect of the thigh. The advantages of this flap are safe elevation, a long vascular pedicle, and large caliber vessel. The donor scar is inconspicuous and it could also be used in a sensated flap. From September 1996 to December 1997, 16 cases of soft tissue defect on extremities were resurfaced with anterolateral thigh free flap and the outcomes were satisfactory. This flap is considered useful in one-stage reconstruction of large soft tissue defects of extremities.

9.Expression of Retinoblastoma Protein in Cutaneous Squamous Cell Carcinomas and Basal Cell Carcinomas.

There is increasing evidence that inactivation of tumor-suppressor genes can promote tumor growth. Retinoblastoma protein (pRb) is the product of the retinoblastoma gene located on chromosome 13q14. pRb negatively regulates cell growth when functioning normally. Mutational inactivation of the Rb gene has been observed in retinoblastomas, osteosarcomas and soft tissue sarcomas. Recently, several other human cancers have also been shown to carry abnormalities of the Rb gene. The potential role of the Rb gene in cutaneous squamous cell carcinomas (SCCs) and basal cell caicinomas (BCCs), has not been determined and was the focus of this study. Immunohistochemical expression of pRb in 16 cutaneous SCCs and 17 BCCs was examined. The expression of PCNA was studied in parallel to assess the cellular proliferation rate in these lesions. The pRb and PCNA immunoreactivity were localized to the nuclei of tumor cells. A few pRb and PCNA positive cells were seen in normal squamous epithelium, sebaceous glands, sweat glands and hair follicles. The loss of expression of pRb was seen in 3 of 16 SCCs(18.8%) and 6 of 17 BCCs (35.3%). PCNA immunoreactivity was slightly high in pRb-negative or lower-positive cases. PCNA immunoreactivity was similar to that produced by pRb in some cases. These results suggest that mutational inactivation of the Rb gene may be related to the carcinogenesis of cutaneous SCC and BCC, though the frequency is relatively low.

10.Four Cases of Eccrine Spiradenoma.

Eccrine spiradenoma is a txnign, painful tumor of the skin, which probably originates in the coil of the eccrine sweat glands and presents a characteristic clinical and pa.hological picture. However recently, the weakness and inconsistency of the enzymes histochemican, actions and electron microscopic findings, and the presence of numerous undifferentiated and indetirn, inate cells suggest a rather low degree of differentiation. We present herein four cases of eccrine spiradenoma which show livrse histopat.hologic characteristics including typical rosette-like structure, ductal structure, vacuar structure and mixed type, respectively. This report may support the premise that eccrine spiridinoma is defived not only from the eccrine duct but also from pluripotential stem cells.
