PURPOSE: To document the radiologic characteristic findings of atypical ductal epithelial hyperplasia, we analyzed film mammographic, ultrasonographic, and MRI findings of our cases. MATERIALS AND METHODS: We analyzed 23 cases of surgically proven ADH, excluding carcinoma in ipsilateral breast. Presence and pattern of neodensity, microcalcification, and architectural distortion were reviewed on mammography. Echo pattern and ductal parenchymal morphology were analyzed on ultrasonography, and enhancement speed and pattern analysis were performed on MRI. RESULTS: On film mammography, ADH showed tendency of neodensity(10 of 23 cases), m icrocalcification(11 of 23 cases), with less parenchymal distortion of surrounding structures(7 of 23 cases). On ultrasonography, ADH was demonstrated as inhomogenous to intermediate echoic nodule(16 of 20 cases) with ragged border(19 of 20 cases), however, its boundary was thin or nearly absent(16 of 20 cases), and showed smooth ductal echography(11 of 20 cases). Gd-DTPA contrast dynamic MR study showed relatively slow and less enhancement in 4 out of 5 cases, with progressive inclination of the speed curve of enhancement in later period of dynamic study. CONCLUSION: Multimodality image approach is needed for better evaluation of ADH, however, excisional biopsy is recommended for confirmative diagnosis and proper treatement.

BACKGROUND: The aim of this study was to assess demographics, clinical outcomes, and complications of classic floating elbow in adults. METHODS: Six patients with ipsilateral diaphyseal fractures of the humerus, radius, and ulna were reviewed retrospectively. All patients were treated operatively and available for follow-up at a minimum of 1 year after surgery. The average age of the patients was 45.2 years (22-64 years) and the average follow-up period was 37.0 months (14-103 months). They were evaluated with postoperative outcome measures, including a visual analog scale (VAS) for pain, Mayo elbow performance score (MEPS), and American Shoulder and Elbow Surgeons (ASES) shoulder score. Residual complications were also evaluated. RESULTS: Five patients (83.3%) had open fracture, and 4 patients (66.7%) presented with associated nerve injury. All fractures were united within postoperative 4 months, except 1 delayed union. The average VAS pain score, MEPS, and ASES shoulder score at the final follow-up examination was 2.5, 79.8, and 67.5 respectively. Three patients including 2 cases of joint stiffness with incomplete recovery from nerve injury and 1 case of complex regional pain syndrome had poor clinical outcome. CONCLUSIONS: Although the classic floating elbow is rare, these injuries potentially have associated problems such as open fracture or nerve injury. The presence of residual neurological symptoms predispose to poorer clinical outcomes.

We evaluated the characteristics of HMB-45 monoclonal antibody(MoAb) and compared it with a polyclonal anti-S-100 antibody in immunohistochemical staining of 22 primary melanomas of the skin ; 13 acral lentiginous melanomas(ALM), 3 superficial spreading melanomas(SSM), 4 lentigo maligna melanomas(LMM), 3 nodular melanomas(NMM). All speimens were formalin-fixed and paraffin-embedded, and were studied with the avidin-biotin-peroxidase complex technique. The results can be summarized as follows : l. In all tissue specimens, all or some of the melanoma cells in the dermis reacted with HMB-45 MoAb and anti-S-100 protein. 2. HMB-45 MoAb is more sensitive in detecting malignant melanoma cell heterogeneity t,han anti-S-100 protein. 3. Melanoma cells within the epidermis in 6 of 12 ALMs and 3 of 4 LMMs did not react with anti-S-100 antibody, whereas most melanoma cells within epidermis of 12 ALMs and 4 LMMs reacted with HMB-45 monoclonal antibody. These results indicated that immunohistochemical staining with HMB-45 MoAb and anti-S-100 protein is very useful in the study of biologic behavior of malignant, melanoma.

A statistical survey was made on 737 cases of cutaneous benign tumors that visited the Department of Dermatology at Seoul National University Hospital during a 11-year period from 1973 to 1983. The results were summarized as follows: 1) There were 329 cases of male(44. 6%) and 408 cases of female(55. 4%). The ratio of male to female was 1: l. 24. 2) Most patients with cutaneous benign tumors belonged to age ranged from 10 to 39 with the highest incidence in the 3rd decade. 3) According to Levers classification, 737 cases of cutaneous benign tumors were divided into following 6 groups: tumors and cysts of the epidermis(252 cases, 34, 2 tumors of the epidermal appendages(125 cases, 17.0%), tumors of fibrous tissue(98 cases, 13.3%), tumors of vascular tissue(158 cases, 21.4%), turnors of farty, muscular and osseus tissue(37 cases 5.0%), tumors of neural tissue(67 cases, 9. 1 %). 4) The distribution of the frequently observed cutaneous benign tumors was as fo]lows: epidermal cyst(12. 1%), nevus flammeus(11. 4%), neurofibroma(9, l%), linear epidermal nevus(7. 9%), syringoma(6, 6%), seborrheic keratosis(7. 9%.). nevus sebaceus(6. 0%), dermatofibroma(5. 8%), steatocystoma multiplex(4. 1%,), tuberous sclerosis(2. 8% ), granuloma pyogenicurn(2. 8%).

A histopathological study of erythema nodosum-like lesions in Behcet's disease was performed on 55 patients with incomplete and suspect types of Behcet's disease. Relatively common characteristics in histopathology of erythema nodosum-like lesions could be found in the patients with incomplete type of Behcet's disease. The histopathologic findings of erythema nodosum-like lesions in 21 patients with incomplete type of Behcet's disease were as follows : l. A moderate lymphocytic infiltration was found around the blood vessels and the sweat glands in the dermis. In the subcutaneous tissue, besides lymphohistiocytic infiltration, neutrophils were present in significant number in 9 cases (42.9%) 2. Vasculitis of small vessels was found within the periphery of fat lobules in 7 cases (81.0%), Five cases (23.8%) also showed thrombophlebitis. Seven cases (33.3%) showed histiocytic granuloma formation within the fat lobules. Microabscess formation in the subcutaneous tissue was seen in 5 cases (23.8 %), but it was not certain whether this was the charateristic feature.

A total of 68 primary melanorna cases diagnosed at Seoul National University Hospital for the past 10 years from 1978 to 1987 were included for this clinico pathological study. Among the 31 primary cutaneous melanomss, 19 cases (61.3%) occurred on hands or feet, especially on the plantar surfaces. The average age of patients with acral melanomas was 49.3 years at the tirne of diagnosis and the male to female ratio of 19 cases was 3.8 to 1. The clinical and histopathologic findings showed that most ecral melanomas, if not all, were the acral lentiginous type. A high incidence of metastasis (73.7%) was recognized in acral melanomas.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.
