OBJECTIVE: This study was performed to evaluate the usefulness of New cervicography by comparing cervicographic finding with Papanicolaou smear and result of colposcopically directed biopsy. METHODS: This study group consisted of 189 patients who visited the Department of Obstetrics and Gynecology, Chung-Ang University Pildong Hospital from September 1998 to August 1999. All women simultaneously underwent Papanicolaou smear and New cervicography. If either method was positive, the patient was referred for colposcopically directed biopsy. RESULTS: The New cervicography was significantly more sensitive than the Papanicolaou smear(92.2% vs 60.8%, p<0.01), whereas the Papanicolaou smear was significantly more specific than the New cervicography(99.3% vs 75.0%, p<0.05). The false positive rate of New cervicography was 75%, significantly higher than 0.7% of Papanicolaou smear. There was no significant difference between the negative predictive value of cervicography and Papanicolaou smear. When New cervicography and Papanicolaou smear were used together, the sensitivity was significantly higher than Papanicolaou smear used alone(98.1% vs 60.8%, p<0.01) and false negative rate was significantly lower than Papanicolaou smear(1.9% vs 39.2%, p<0.01). However the specificity, positive predictive value of the combined test were lower than Papanicolaou smear. CONCLUSION: Cervicography is one of the Papanicolaou smear adjunctive tests and a useful method to detect cervical cancer. Our study confirms the previously suspected low sensitivity of Papanicolaou smear and demonstrate that cervicography is more sensitive than Papanicolaou smear and less specific. From the above results, when New cervicography and Papanicolaou smear were used together, the detection rate of cervical cancer will be increased more easily since the cases missed by one method may be picked up by another.

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.

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.
