Background: Dermatofihromas are relatively common benign tumors which occur in the skin. However, clinical and histopathological studies have been rarely reported in Korea. Objective : This study was taken to evaluate the clinical and histopathological features of dermatofibromas in Korea. Methods : Fifty cases of dermatofibromas were selected from 10 years of laboratory files for during the period January 1985 to December 1994 at Chung Ang University Hospitals. Results : 1. The age range was from 18 to 61 and the average age at diagnosis was 38.7(male;37.6, female;39.4). The ratio of male to female was 1.0: 1.6(19:31). 2. The diameter of the dermatofibromas : 1) 5-20mm;32 cases(64.0%), 2) 5mm>;8 cases(16.0 %), 3) 20mm<;7 cases(14.0%), 4) unrecorded;3 cases(6.0%). 3. The most common color was brown(14 cases, 28.0% ), and other common colors were skin-color(7 cases, 14.0%), red(4 cases, 8.0%), black(3 cases, 6.0%), violaceous(2 cases, 4.0%), unknown(20 cases, 40.0%). 4. Thirty seven cases(74.0%) had solitary lesions, and thirteen cases(26.0%) had multiple lesions. 5. The lower extremeties(39 cases, 50.6%) were the most common sites followed by the back (10 cases, 13.0%), upper extremities(9 cases, 11.7%), shoulders(8 cases, 10.4%), abdomen(4 cases, 5.2%), hands(2cases, 2.6%), face(2 cases, 2.6%), neck(2 cases, 2.6%), breast(1 case, 1.3%). 6. Histopathologically, fibrous types were seen in 40 cases(80.0%), cellular types in 3 cases(6.0 %), mixed types in 5 cases(10.0%), and sclerosing hemangiomas in 2 cases(4.0%). Conclusion : The 50 cases of dermatofibromas, which were confirmed at Chung Ang University Hospitals from January 1985 to December 1994, were reviewed clinically and histopathologically.
