Photodynamic Therapy Using HMME for Port-Wine Stains: Clinical Effectiveness and Sonographic Appearance

Figure 1

Comparison of the efficacy of HMME-PDT in the treatment of PWS, after three treatments. Case 1: 35-year-old female patient with pink lesions under the left orbit, back of the nose, cheeks, and upper lip. After three HMME-PDT treatments, the patient's cheek skin gradually changed from pink to light red, and the suborbital, dorsal nasal, and upper lip skin lesions basically subsided. Case 2: a 24-year-old female patient with bright red patches on the right iliac temporal, cheek, nose, and upper lip, and slight swelling of the right lip corner. After three HMME-PDT treatments, the bright red patches on the lesions subsided by about 65%, from bright red to light red, mild pigmentation of the crotch skin. Case 3: 26-year-old female patient with purple patches on the left parotid gland and mandible with purple-red lesions. She had had hypertrophic scars in the mandible after laser treatment. After three HMME-PDT treatments, the lesions subsided about 80%. Case 4: a 28-year-old female patient with dark purple patches on the left orbital condyle and cheeks, with a slightly thickened skin surface. After three HMME-PDT treatments, the color of the skin lesions gradually changed from dark purple to pale red, the skin at the thickened area was basically flat.
