Primary tumors of the adrenal cortex are comparatively rare. In the medical literature they are most frequently reported as single case. Because of their infrequent occurence some features of their clinical behavior and pathologic anatomy are not widely known. For this reason the recording of the 7 cases from the Department of Pathology, School of Medicine, Chungnam National University is thought to be worth while. Of the seven tumors, five were associated with primary aldosteronism, one Cushing's syndrome, and the remaing one virilizing syndrome. All were benign. Females were affected more frequently than males. Adrenocortical adenomas tend to be small, weighing less than 42 gm. The tumors associated with primary aldosteronism were composed of zona fasciculata-like cells and "hybrid" cells. The tumor with Cushing's syndrome consisted of zona reticularis-like cells. The tumor with virilizing syndrome consisted of zone reticularis-like cells.

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

Fordyce's disease is a condition known as ectopically located sebaceous glands on the vermilion borders of the lips and oral mucosa. Clinically, it is groups of minute, yellowish, globoid macules and papules. Histologically, it is characterized by sebaceous glands not associated with hair follicles. We report on a 40-year-old man with Fordyce's disease showing particularly wide distribution on the buccal mucosa and upper lip.

Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

9.Posterior Atalntoaxial Fusion with C1 Lateral Mass Screw and C2 Pedicle Screw Supplemented with Miniplate Fixation for Interlaminar Fusion : A Preliminary Report.

OBJECTIVE: To investigate the feasibility of C1 lateral mass screw and C2 pedicle screw with polyaxial screw and rod system supplemented with miniplate for interlaminar fusion to treat various atlantoaxial instabilities. METHODS: After posterior atlantoaxial fixation with lateral mass screw in the atlas and pedicle screw in the axis, we used 2 miniplates to fixate interlaminar iliac bone graft instead of sublaminar wiring. We performed this procedure in thirteen patients who had atlantoaxial instabilities and retrospectively evaluated the bone fusion rate and complications. RESULTS: By using this method, we have achieved excellent bone fusion comparing with the result of other methods without any complications related to this procedure. CONCLUSION: C1 lateral mass screw and C2 pedicle screw with polyaxial screw and rod system supplemented with miniplate for interlaminar fusion may be an efficient alternative method to treat various atlantoaxial instabilities.

OBJECTIVE: The purpose of this study was to evaluate the outcome and safety of vaginal delivery after previous cesarean birth. METHODS: This study was based on 303 cases of delivery with previous cesarean birth at Masan, Fatima Hospital from May, 1997 to April, 1998. Among them, 62 cases had performed trial of labor. We had made a comparison between elective repeat section group and trial of labor group by analizing the frequency, successful rate, maternal morbidity, perinatal morbidity and mortality. RESULTS: Among 303 cases with previous cesarean birth, trial of labor was done in 62 cases(20.5%). Among trial of labor group, vaginal delivery was done in 54 cases (87.1%) and repeat section was done in 8 cases(12.9%). Indications for elective repea section before the onset of labor were refuse trial of labor(51.9%), request for tubal ligation(17.4%), and previous section > or =2(7.5%), etc. The successful rate of vaginal delivery according to indication for previous cesarean birth was 85.0%(17/20) in the cases of dystocia and 88.1%(37/42) in the cases except dystocia. The successful rate was not influenced by the indication for previous cesarean birth(P>0.05). There were no maternal death or uterine rupture in the cases of trial of labor. There were no significant difference between elective repeat section group and trial of labor group in maternal morbidity, perinatal morbidity and mortality(P>0.05). CONCLUSION: Under strict indications, vaginal delivery subsequent to cesarean birth may be safe, and can reduce the rate of cesarean section that was increased constantly.
