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.

7.Four Cases of Eccrine Spiradenoma.

Korean Journal of Dermatology 1995;33(1):140-144
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.

Lichen nitidus, characterized by its typical clinical and histopathologic findings, is an uncomrnon chronic dermatosis of unknowned etiology. The distribution of this disease is most often localized, but in some cases it may becorne generalized. Some authors suggested that lichen nitidus is a variant of lichen planus in terms of its coincidence, ultrastructural and immunophenot,ypic studies. We report herein a case of lichen nitidus which presents dark brown linear, grouped, or confluent papules on the face, cheat, and upper extremities, accompanying with the histopathologic findings of pigmentary incontirence in the portion of claw clutching a ball appearance. This report suggests that lichen nitidus shows hyperpigmentation clinically and could be one of the dermatoses which exhibit pigmentavy incontinence in a histopathologic study.
