Friction melanosis is frequently developed in thin, young woman, on thc covered skin of spinc, rib, elbow, knee and tibia. These lesions range from brown to rcddish-brown in color, appear in either band shapes or reticular patterns, and exhibit no overt syrnptoms. They do not show any inflamatory changes, and the skin remains smooth. According to histopathological findings, the main changcs arc perivascular melanophages on the papillary derrnis and upper dermis, and also increased melanin granules on the basal layer. The following case concern a relatively thin 20-year-o1d female patient. She had a syrwptoniless brown color changcs above the ribs of back, growing in dircction of the ribs for a period of three years. This change was band shaped, but there were no signs of inflammatory reaction, leaving the skin smooth. A biopsy was performed on the relevant tissue, and clinical-histopathological analysis was resulting in diagnosis of friction melanosis.

A 33-year-old man had multiple, dome shaped, pin-head sized, hard papules on the center of face and pigeon's egg sized hard tumors on the left upper arm and the trunk. The histopathological findings of the skin biopsy specimens from face and left upper arm showed tumor islands composed of basophilic cells of the same sppearance as basalioma cells, arranged in a lacelike and solid aggregates, without horn cysts.

OBJECTIVES: To investigate the factors associated with symptoms from job stress among Korean dental laboratory technicians. METHODS: We collected the data of 786 technicians for life-style, job stressor, social support, self-esteem, personality, and various dimension of stress symptoms included roomatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility by self-administerd questionnaire. Global severity index of dental technician (GSID) was calculated by total sum of sub-dimension. RESULTS: We used 80 percentile as a cut-off point, and got the 81.5 % of sensitivity, 86.1 % of specificity by receiver operating characteristic curve. The odds ratios of various factors in high group of GSID compared with low group were 1,49(95 % Cl 1.00-2.00) for smoker, 1,53 (1.06-2.21) for unhealthy group, 6,69 (4.74-9.44) for work overload, 8.34(5.82-11.97) for work demand, 9.89 (6.76-74.94) for work process, 8.27 (5.80-11,79) for work environment, 5.82 (4.04-8.39) for interpersonal relationship, 8.34 (5.82-11.97) for occupational conflict, 5.70 (4.04-8.04) for labor remuneration, 7.58 (5.37-10.71) for role conflict, but 0.39 (0.27-0.57) for social support, 0.41 (0.29-0.60) for self-esteem. By multiple logistic regression, factors were significantly associated with GSID were age, working area, role overload, work demand, work procedure, physical environment, occupational conflict, role conflict, social support, personality traits. CONCLUSIONS: Factors associated with symptoms from stress were role overload, work demand, work procedure, occupational conflict, interpersonal relationship, labor remuneration and role conflict in Korean dental laboratory technicians. It is suggested that health promotion program to reduce job stress and to enforce social support and self-esteem should be developed.

PURPOSE: To evaluate the relationship between the hormonal receptor status and the mammographic finding in breast cancer, thus to disclose whether the mammorgraphic findings would be the prognostic predictor or not. MATERIALS AND METHODS: Fifty breast cancer patients with hormonal receptor assay were included in this study. Hormonal status and mammographic findings were evaluated to disclose the relationship between the two variables. RESULTS: Among 26 positive estrogen receptor(ER) patients, 23 cases showed spioulations, 4 cases with increased parenchymal densities, 15 cases with calcifications, and 18 with mass-like lesions. Among 25 positive progesterone receptor(PR) patients, 22 cases showed spiculations, 6 with increased parenchymal densities, 12 with calcifications, 17 with mass-like lesions. Among 24 negative ER patients, 10 showed spiculations, 9 increased parenchymal densities, 12 calcifications, and 13 mass lesions. Among 25 negative PR patients, 17 showed spiculations, 8 increased parenchymal densities, 15 calcifications, and 13 mass lesions. CONCLUSION: Spiculation in mammography could related to the high incidence of positive estrogen receptor.
