结果 ①524例寻常型银屑病患者进行期皮损以点滴状居多，稳定期患者以点滴状、钱币状、地图状为主，环状、带状则少见。而退行期则以点滴状、钱币状、环状、带状多见。②103例寻常型银屑病患者皮损的初发部位和421例再发患者皮损的现分布部位均以头皮最多，其次是小腿、肘、大腿等，最少见于粘膜、甲、外生殖器等。

Twelve tumors were solid and three contained cystic components. Nine were inhomogeneously hypoechoic. Two were homogeneously hypoechoic. Two were inhomogeneously isoechoic. Two were homogeneously isoechoic. Two contained microcalcification. One with acoustic shadowing. Twelve were well-defined and three were ill-defined. Fourteen were regular and one was irregular. Four had acoustic halo. Six were ecstatic. Nine were not ecstatic. Thirteen were examined with color Doppler ultrasound. Nine had abundent branched blood flow within the tumor and ring blood flow around. Two had short linear blood flow within the tumor and ring flow around.
