We present a case of acquired, bilateral nevus of Ota-like macules in 50-year-old women, She had deeply brownish, confluent or solitary macules and patches distributed symmetrically on the both side of the forehead and temple, since years ago. But there was no involvement (of ocular and oral mucosa. Histopathologic findings showed flattening of the rete ridges and elongated or irregular shaped melanocytes containing many melaiiin granules, in upper-and mid-dermis. And most of melanocytes showed positive reactions on Dopa stain.

We experienced a case of scrotal calcinosis which was considered to be developed from the trichilemmal cysts of the scrotum. This 22 year-old male patient has been suffered from pea-sized hard muliple yellowish nodules of the scrotum since. about 5 years ago. Histopathologic findings revealed multiple cysts or calcium lumps surrounded by variable a.mounts of granulomatous inflammatory infiltrations in the dermis. The cysts were lined by stratified squamous epithelium without intercellular bridge and surrounded by scanty inflammatory cells. Several cysts contained homogenous keratinous material but most cysts contained calcium deposits within the homogenous keratinous materials or only the calcium lumps in the intact epithelial linings. Most of calcium lumps which had partially or completely disintegrated epithelial linings were surrounded by active granulomatous inflammatory infiltrations and a few calrium lumps with completely disintegrated epithelial linings had no surrounding inflammatory cells. Observing the above histopathologic features, we could consider that this case of scrotal calcinosis was developed from the scrotal trichilemmal cyst and some cases of idiopathic scrotal calcinosis, previousely reported, were the end stage of the above process.

A clinical and histopathologic study was done on 48 cases of cutaneous tuberculosis among 43, 209 out-patients in Dermatologic department of Korea t.Jniversity Hospital during the period of 15 years and 9 mont4s from January, 1969 to September, 1984. These 48 cases were consistent with skin tuberculosis in histologic and clinicalI finc1ings, The result were summarized as follows: ]. The incidence of skin tuberculosis was 0 I 1 g among 43, 209 cases of outpatients. 2. Localized type of skin tuberculosis was 3. 2 times more frequent than disseminated type. Frequent skin tuberculosis was lupus vulgaris (57 3%), erythema induratum (12, 5%), tuberculosis verrucosa cutis(8.3%) and lupus milaris disseminatus faciei (8. 3%). 4, The ratio between male and fenmle was 1: l. 1. 5 The ages of onset were variable according to the types of skin tuberculosis. but 45 8% of all cases developed in the age group between 10 and 29 years. Seasonal incidences of skin tuberculosis were 52. 1% in spring, 85%, in winter, 18. 8% in summer, 4, 2%, in autumn. 7 In histopathologic findings, there were tubercle or tubrculoid structures in all cases and typical tubercle structures were observed in 18.8% The ratio of accordance between the histopathologic diagnosis and clinicopa thologic diagnosis was 81.3%.

The relative merits of cartilage scoring versus suturing in techniques for correcting the prominent ear remains a subject of debate among leading plastic surgeons. We compared a variety of echniques for correcting the prominent ear in 72 rabbit ears using scoring, horizontal mattress sutures, and combination scoring and suturing. The ears were splinted with a right-angle fold for 3 postoperative weeks, and the animals were sacrificed after 8 weeks. Suturing techniques in combination with scoring maintained an angulation significantly closer to the desired 90 degrees than cartilage scoring or cartilage suturing only(p<0.05). Histological analysis demonstrated a significant increase in cartilage hyperplasia by suturing alone, whereas the other techniques achieved only mild to moderate increases. We recommend cartilage scoring and suturing through skin incision on severe degrees of prominent ear, and cartilage needle scoring and buried suturing through slit incision on mile-to-moderate degrees of prominent ear.

Thirty-six cases of paroxysmal supraventricular tachycardia which were observed at the Department of Pediatrics, Seoul National University Hospital from 1976 till October 1982, were analyzed. 1. The sex ratio was 1.8:1, male predominance. Sixteen cases (44.4%) were under 1 year of age and 11 cases (30.6%) were under 4 months of age. 2. Cases without known heart disease were 22(61.6%). Among Known etiology, most frequent one was 7 cases(19.4%) of W-P-W syndrome. 3. The sex ratio of group without known heart disease was 2.1:1, and that of group with known heart disease was 1.3:1. Under 4 months of age, there were more cases without known heart disease(72.7%) and after 4 months of age number of cases with and without known heart disease were similar. 4. Most frequent clinical manifestation was tachydyspnea. hepatomegly, irritability, palipitation, cyanosis and pallor, vomiting, chest pain, edema, abdominal pain, and fever were followed in order of frequency. 5. Congestive heart failure occurred in 22 cases(61%). The incidence was related to the duration of attack of tachycardia, age of patients, and heart rate. The longer the duration of attack and the younger the age of patients and the faster the heart rate, the higher incidence of heart failure was observed. 6. As treatment, vagal reflex stimulation was almost ineffective, and digitalization was effective in most of the cases. Verapamil and electrical cardioversion were tried in small number of cases and proved to be effective. 7. One case (2.8%) expired becase of the supraventricular tachycardia. 8. Eight cases (30.8%) had recurrence. In younger age group, recurrence rate was lower. 9. Digoxin was given in 15 cases for prevention of recurrence and was effective in 12 cases.

A 68-year-old man was refered for evaluation and treatment of advanced esophageal cancer. He complained of substernal dysphagia for solid and liquid foods. He did not remember episodes about ingesting something that correlated with symptoms. The single-contrast esophagogram revealed subtotal obstruction of the cervical esophagus with barium outlining the polypoid-filling defect irregularly. After 18 hours later, the patient underwent endoscopic examination and at the direct esophagoscopic finding, the food materials mainly consisted of packed rice was filled in the cervical esophagus. After saline irrigation, a fish bone, which was about 50X9 mm, and looked like a knife was lodged just distal to the impacted food materials. The fish bone was removed successfully from the esophagus. The patient experienced dramatic relief of symptoms shortly after procedure.
