EVALUATION OF HIGH-FREQUENCY ULTRASONOGRA PHY (20 MHZ) IN CUTANEOUS TUMORS

The purpose of the present study is to assess the value of high freque ncy ultrasonography (20 MHz), a new noninvasive imaging technique, in cutaneous tumors. Cutaneous tumors are clinically varied and their dia gnosis is still based on histopathological analysis. 140 cutaneous tum ors have been examined with US and imaging findings have been compared to the results of clinical and histological examinations. This study shows that high frequency ultrasonography, even though it cannot repla ce pathological analysis, may help the dermatologist in the positive d iagnosis of some cutaneous tumors and in accessing the location and th e in depth-extension of the lesions in the differents layers of the sk in.
