Abstract

BACKGROUND
Skin Biopsy is a equently used diagnostic tool in dermatology and clinical impressions before biopsy may be different with pathologic diagnosis. OBJECTIVES: The purpose of this study was to investigate the concordance rate of clinical impression and pathologic diagnosis. METHODS: Clinical and Pathological studies were done on 559 biopsied skin diseases among 16, 944 out-patients in Dermatologic department of Chungnam University Hospital during the period of 1 year from March, 2002 to February, 2003. RESULTS AND CONCLUSION: The study results are summarized as follows: 1. The most frequently biopsied skin disease group was non-tumor, noninfectious disease (40.8%), followed by benign tumor (37.4%), infectious disease (11.8%), malignant tumor (10.0%). 2. The concordance rate between clinical impression and pathologic diagnosis showed 68.9% in complete agreement and 79.6% in complete and partial agreement. 3. The concordance rate of professor committed cases was 68.8% and that of residents committed cases was 69.1%. 4. The concordance rates among disease groups were highest in malignant tumor (74.6%), then benign tumor (70.8%), non-tumor infectious disease (67.4%) and non-tumor noninfectious disease (65.2%).
