Many articles concerning the accuracy of diagnosis of malignant tumor cells in body fluids have appeared in the literature, but few authors have attempted to describe the characteristics of these cells to determine the site of the primary tumor as they relate to tumors of specific primary sites. This paper presents the results of a retrospective study on malignant body cavity effusions of which the primary site was established on the basis of either biopsy or surgical resection of the primary neoplasm during the period of 6 years beginning from January 1983 to December 1988. The results obtained are summarized as follows: 1) The 143 fluid specimens from 129 patients were composed of 51 cases of pleural, 69 of peritoneal, and 9 of pericardial origin. 2) Adenocarcinoma was the most frequent type of malignant effusions (78.3%). The most common primary site was the lung (50%) in pleural fluid and stomach (55.2%) in ascites. 3) The results of this study show that the primary site of tumor cells can be identified in the body fluid of accurate cytomorphologic criteria are used. Identification of the primary site of an effusion would be improved by the consideration of clinical information

The warts are benign skin tumors caused by virus, most frequently seen in childhood, and have atendency to regress before reaching adulthood. Various articles have been suggested that wart involution may be involved with immune response of the host, but definite mechanism has not been found. The author studied the tuberculin sensitivities of the wart patients in order to evaluate immune responses of the hosts, and observed the course of the warts after BCG vaccination to the patients for the facilitation of nonspecific immune reaction of the hosts. The results are as follows; 1. Tuberculin positivity was not decreased, however the sensitivity to the tuberculin was decreased among the wart patients than the non-wart groups. 2. No significant difference was observed between the numbers of wart and the degrees of tuberculin sensitivity. R. BCG vaccination was promoted the invotution of warts without valuable changes of the tuberculin sensitivities.

Clinically, benign juvenile melanoma (BJM) is a benign nevus-cell tumor and arise predominantly in children. The lesion usually is solitary and is encountered most commonly on the face and extremities. In most mstances the lesion consists of a dome-shaped, srnall nodule. The histoIogic picture often closely resembles that of a maIignant melanoma and there is no doubt that prior to its recognition as an entity by Spitz in 1948 many cases were misdiagnosed as malignant melanoma. A case of benign juvenile melanoma in 23-year old male is described with brief review of literatures. Hisr.ologic pictures show considerable junctional activity. In the upper dermis edema and ectasia of the various vascular elements are present. The re:us cells are pleomorphic. They are mostly spindle-shaped and are arranged mostly in fairly well circumscribed nests. Giant cells are frequentIy observed. Melanin is scanty and mitotic figures are absent. These are typical histologic pictures of the BJM, To our knowledge, there have been no prior repots of BJM in Korea, based on our own review.

Human wart diseases are benign skin tumors caused by viruses of the papova group which usually affect children and almost always regress until adulthood. Various therapeutic modalities have been tried for the treatment of warts, however there is no single satisfactory method and the clinical course as well as the prognosis is always variable. The spontaneous regression of warts may represent an increase in the activity of host immune responses. Recent studies have tended to confirm that serum antiviral antihodies and cellular immune responses occur in relation to regression of warts, but there is no convincing evidence of a correlation between the appmrance of immune responses and resolution of the warts. BCG and some of similar extra,cts have becn known to be capable of initiating a wide range of non-specific immune reactions to cancerous diseases. The aim of the present investigation has been to study no-specific irnmune response of Tubercin-3 in patients with svarts, based on the findings that RCG and some of similar extracts were found to be a potent reticuloendothelial stimulant. Taventy casee attending a, dermatolo-ical out-ptient department consists of eight verrua plana juvenilis, seven verruca vulgaris, one verruca plxntaris and four molluscurn contagiosum were trezted with Tubercin-R. The results revealed complete cure in six(37. 5.) and clinical improvemeat in nine. (56. %) of sixteen cases of various warts, and one of four czses of molluscum contagiosurn showed a slight decrea,se in size and nu!nber of the lesions. There is no eviclence of a correlation among the age of patient, type of verruca and therapeutic effect. On the basis of our findings, we can state that non-specific immune response of BCG .and some of similar extracts may be facilitate the involution of warts. The relationship of thes immune respons to the involution of warts clezrly require further study.

Aberrant left-sided pulmonary artery(pulmonary artery sling) is an uncommon anomaly, which may cause significant respiratory abnormality. We report a case of pulmonary artery sling which is combined with persistent left superior vena cava and dextrocardia. This case was identified by esophagogram and CT and confirmed by MRI and angiography. We consider that MRI is a valuable new method for the diagnosis of aberrant left-sided pulmonary artery.

The varicocele, a correctable cause of male infertility, affects both testes in histologically and physiologically, and the testicular damage is related to the duration of the varicocele. But the correction of an adolescent with a varicocele is controversial. To evaluate the efficacy of early surgical correction of the varicocele, seminal analysis was compared preoperatively and postoperatively for 6 months in 52 adolescents. In all the patients, improvement of postoperative men quality was observed with statistical significance, but morphology was not changed. operative abnormal semen quality was noted in 12 patients and was improved in 5 patients postoperatively. According to this results, early diagnosis and early surgical correction in adolescent with varicocele maybe prevent further testicular damage and increase fertility ultimately.

The cause of radiolucent filling defects in the upper urinary tract are malignant tumor, radiolucent stones, blood clots, air bubbles, congenital deformities of renal parenchyme, and various specific and non-specific infection and their sequence. So the differential diagnosis between malignancy and radiolucent stones is very important, and the exact and fast diagnosis of radiolucent stones is useful in excluding the possibility of malignancy. 27 cases with radiolucent stones were evaluated retrospectively for exact diagnosis and appropriate treatment method. Intravenous urography was done in all cases, and retrograde pyelography, ultrasonography, computed tomography and/or ureterorenoscopy were performed for diagnosis, if needed. Size of stones were measured below 10mm by transverse length in 19 cases (70.4%) with a range of 3 to30mm. The locations of stones were pelvocalyceal system in 8 cases (29.6%) and ureter in 19 cases (70.4%). Among the diagnostic methods, computed tomography was used most frequently. ESWL with retrograde pyelography was most frequent used method of treatment, also simple hydration to small stone was effective.
