DNA isolated from human tumor cells can induce malignant transfarmation of tissue culture cells. The DNA is then called an oncogene. Its protein produets have been detected in animal and human tumors and are considered to play a significant role in carcinogenesis. In order to evaluate whether the oncogenes are involved in development of tumors of epidermis and whether they could be used as tumor markers, immunoperoxidase staining was performed for the ras product in sections of squamous cell carcinoma, Bowen's disease, actinic keratosis, keratoacanthoma and seborrheic keratosis. Three cases of sgamous cell carcinoma showed 10~20 positive cells per high power field(HPF). Three cases of Bowen's disease revealed 1-9 positive cells per HPF, whereas the actinic keratosis 1~9 or no positive cells per 10 HPF in all three cases. The keratoacanthoma and seborrheic keratosis showed 1~9 or no positive cells in all observed cases. The positive staining was observed in the cytoplasm. The increasing positivity in parallel with the increase of malignant potential strongly suggests that the ras oncogene is closely related to development of epidermal malignancy and also point out the possibility of ras as a cancer marker.

BACKGROUND: Although the culture of urethral discharge using a cutton swab is regarded as one of the most sensitive and reliable diagnostic methods of gonorrhea, it may give pain or diagnostic methods of gonorrhea, it may give pain or discomfort to patients, and its detection rate may be influenced by the examiner's technical ability. OBJECTIVE: The purpose of this study was to compare the positive culture rates between ure4thral discharge and urinary sediment for the diagnosing of Neisseria gonorrheae. METHODS: We compared this technique with the culture of urethral discharge using the specimens from 357 male patients with gonococcal infection at VD clinic of Jungku Pvblic Health center in Seoul from Jan 1991 to Jun 1993. RESULTS: The culture of urinary sediment was positive in 339 of 357(94.95), whereas the culture of urethral discharge was positive in 346 of 357(96.95). However, these data have no statistical significance(P<0.05). The obe observed sensitivity and specificity of culture of urinary sediment comjpared to culture of urethral discharge were 97.75 and 90.9%, respectively. The predictive value of positive and negative test compared to the culture of urethral discharge were 99.7% and 55.65, respectively. As our data showed low negative predictive value, a negative culture result of urinary sediment does not always imply a negative culture result of urethral discharge. CONCLUSION: Therefore, at present, the previous method of the culture of urethral discharge is more highly recommended and further studies for this diagnostic and/or new method of gonorrhea based on larger group of patients is encouraged.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriafsis, but it has been also descrilbed in conjunction with a host of other disordered. We described five cases of erythema multiforme showing lesions of easily recognizsble Koebnei phenomena. Traumas to the skin do not cause erythema multiforme, however when a patient is in an active stage of the disease, physieal factor such as traumas occuring in normsl daly-life may contribute to the distribution of skin lesions as have been seen in our patients ; clinicians should aware of this point for better understanding of clinical features in erythema multiforme.

Marjolin's ulcer is a malignant degeneration of cicatrical tissue, especially in chronic burn scar. Since the first description by Jean Nicholas Marjolin(1828), many studies for Marjolin's ulcer have been performed and reported. From 1985 to 1997, we experienced 20 cases in 14 patients diagnosed as Marjolin's ulcer clinically, and we analysed malignant transformation rate, induction period of Marjolin's ulcer and prevention of Marjolin's ulcer, etc. The results are summarized as follows. 1) The sex distribution was predominant in male(64.3%). 2) The most common cause of injury was flame burn(78.6%). 3) The mean age at the time of diagnosis was 45.6 years and the average lag period was 20.6 years. 4) The pathologic types of Marjolin's ulcer were squamous cell carcinoma(57.2%), followed by dyspasia(28.6%), acnthosis and hyperkeratosis(14.2%). 5) The locations of ulcers were frequently on the lower extremity(42.9%), followed by upper extremity(35.7%) and trunk (21.4%). 6) The lymph node involvements were 3 patients out of the 8 patients who were confirmed as squamous cell carcinoma. 7) The modalities of treatment were skin graft (18 cases, 12 patients), myocutaneous flap(1 case, 1 patient), fasciocutaneous flap(1 case, 1 patient).
