Marshall-White综合征1例OA

A case of Marshall-White syndrome is reported.A 27-year-old male presented with leukoplakia on the upper limbs that had increased progressively for over four years.Multiple scat-tered round or quasi-round white spots with a diameter of about 0.2-1.0 cm could be seen on the upper limbs.The lesion boundary was clear,and the surface was smooth and free of scales.The white spots could be seen to fade or even disappear after rubbing or raising the arms.The dermo-scopic examination showed a white unstructured area with a light red background and multiple scattered punctate globular telangiectasia around the upper limbs.After the upper limbs were lifted or rubbed,the background skin color could be seen,the white unstructured area was obviously lighter than before,and the original dot globular telangiectasia around it was significantly reduced.The diagnosis was Marshall-White syndrome.No treatment was given.
