Two typical cases of epithelioid sarcoma were examined by immunohistochemical stain using antibodies to epithelial membrane antigen, carcinoembryonic antigen, vimentin and cytokeratin. Both cases showed positive reactivity for the four kinds of antibodies. These results point to the fact that epithelioid sarcoma simultaneously expresses epithelial markers and characteristic mesenchymal phenotypes. Epithelioid sarcoma appears to be a tumor derived from a multipotential mesenchymal cell with multidirectional differentiation.

A 12-year-old girl presented with a 1-week duration of hair loss associated with splitting of the hair ends and whitish dots on the occipital hairs. On microscopic examination, a longitudinal splitting of the hair shaft with reconstitution of the normal hair distal to the fracture, nodular swellings, with the appearance of broomsticks pushed into one another, at the site of whitish swellings, and the flattening and twisting of the hair shaft around the long axis were demonstrated. Minor trauma to injury-prone hair is a common cause of hair shaft defects, however the reports with the combined conditions are insufficient in the literature. We describe a patient with central trichoptilosis associated with localized trichorrhexis nodosa and pili torti.

Ultrasound studies of sixty five patients with thyroid mass histologically proven at KyungPook NationalUniversity Hospital from June 1983 to May were retrospectively analized. No specific sonographic characteristicsof thyroid mass lesions was found on the basis of histological diagnosis. Authors consider that ultrasound studymight be mere useful for detection and localization of a lesion, and guide to needle aspiration, monitoring thesize of a mass following therapy as well.

A clinical analysis were made on 104 cases of congenital anomalies of the genitourinary tract in childhood who had been admitted to the Department of Urology, Maryknoll Hospital during the period from January, 1976 to December, 1982 and following results were obtained. 1. Among the total number of patients(1248 cases)admitted to the Urologic Department, 170cases (13.6%) were pediatric patients. 2. Among the total number of pediatric patients, 104 cases (61.2%) were congenital anomalies of genitourinary tract. 3. The ratio of male to female was 51:1. 4. Age distribution of the congenital anomalies showed higher concentration between age of 6years and 12 years. 5. The frequently involved organs of the genitourinary tract in anomalies were genitalia (77.9%), and followed by urethra (16.3%) and Kidney (3.8%) 6. The incidence of complications among the urinary tract anomalies was 4 cases (17.4%). And the most frequent complication were hydronephrosis (75%), and followed by pyelonephritis(25%) and vesicoureteral reflex (25%). 7. The most frequent anomalies according to pathological features were cryptorchism (47.5%) among the total number of genitourinary tract anomalies and other were hypospadias (15.3%), hydrocele (10.2 %), phimosis (5.9 %) in frequency of orders.

Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.

Hydroxyurea is an effective treatment for a variety of myeloproliferative disodrers. A distinct cutaneous reaction to long-term administration of hydroxyurea has been characterized and designated hydroxyurea dermopathy. Epidermal dysmaturation refers to histologic changes that may be observed in the epidermis after any significant cytoreductive therapy. We report a patient with hydroxyurea-induced dermatomyositis-like eruption showing epidermal dysmaturation who developed an erythematous scaly patches on the dorsal aspects of the hands while on long-term administration of hydroxyurea for chronic myelogenous leukemia.

Condyloma acuminatum is a common viral disease which is transmitted by sexual intercourse. We experienced a case of condyloma acuminatum occurring in a patient of systemic lupus erythematosus who has been treated with various immunosuppressive agents for 10 years. This condylorna acuminatum was unusual in that it was very rapidly growing, recurrent and reluctant to various treatrnents. We investigated the type of human papillomavirus by Southern blot hybridization and schieved partial improvement by bleomycin intralesional injection together with 5-FU topical application.

The increasingly successful results of hair restoration surgery in the last years have developed the interest and the confidence of patients and it is the most frequently performed esthetic surgery among male patients. Currently, various kinds of techniques for hair restoration surgery including hair transplantation, scalp reduction, and scalp flaps are performed in our clinic. Among these, hair transplantation is the basic and the most popular procedure, which can be performed not only by itself but also in conjunction with other procedures. 123 consecutive cases of hair transplantations were peformed from Jan. 1995 to Feb. 1996 for male pattern baldness, traumatic alopecia, and female pattern baldness under out patient base. The authors introduced a new classification for male pattern baldness, which are the type M, O, C, U, M-O, and C-O after alphabet to make simple and easy for clinical application. The ancillary procedures were scalp reduction, preauricular flap, and scalp expansion. An ellipsis of hair bearing scalp taken from the occipital area was sliced into slit-, mega-, mini-, and micro-grafts. The survival rate of the grafts was over 90% with minimal complications. This hair transplantation technique enabled us to achieve a good density and more natural looking hair with avoidance of cobble stoning and apparent scar.

Trichorrhexis nodosa(TN) denotes small node-like swelling with a loss of cuticle of the hair shaft through which the hair readily fractures. The basic cause of TN is mechanical or chemical trauma, and a contributing factor is an inherent weakness of the hair shaft. We report a case of localized TN in a 37-year-old male. He had an ovoid hair patch with multiple small white-gray dotted and stubby hairs localized to the right occipital scalp. TN is known to be the commonest of all hair shaft anomalies (Price, 1975). However TN is rarely reported, and there have been only four reports in Korean dermatological literature, to our knowledge, which might be due to underdiagnosis of this disorder. We postulated that diagnostic difficulty lies in the discrepancy between terminology and gross morphological findings.
