Test treatment of portwine stains (PWS) was performed with a microsecond‐pulsed dye laser at 577nm using a 2‐mm spot diameter. Although selective coagulation of the erythrocytes occurred, this did not result in bleaching of the treated area. Massive destruction of the dilated capillaries is suggested to be a prerequisite for PWS‐bleaching, very probably requiring msec (instead of μsec) laser pulses.
