Nonconventional Use of Flash-Lamp Pulsed-Dye Laser in Dermatology

الملخص EN

Flash-lamp pulsed-dye laser (FPDL) is a nonablative technology, typically used in vascular malformation therapy due to its specificity for hemoglobin.

FPDL treatments were performed in a large group of patients with persistent and/or recalcitrant different dermatological lesions with cutaneous microvessel involvement.

In particular, 149 patients (73 males and 76 females) were treated.

They were affected by the following dermatological disorders: angiokeratoma circumscriptum, genital and extragenital viral warts, striae rubrae, basal cell carcinoma, Kaposi’s sarcoma, angiolymphoid hyperplasia, and Jessner-Kanof disease.

They all underwent various laser sessions.

89 patients (59.7%) achieved excellent clearance, 32 patients (21.4%) achieved good-moderate clearance, 19 patients (12.7%) obtained slight clearance, and 9 subjects (6.1%) had low or no removal of their lesion.

In all cases, FPDL was found to be a safe and effective treatment for the abovementioned dermatological lesions in which skin microvessels play a role in pathogenesis or development.

Further and single-indication studies, however, are required to assess a standardized and reproducible method for applying this technology to “off-label” indications.
