Eczema as a Complication of Pulsed Dye Laser Therapy

Local molluscum contagiosum infection as a side-effect of pulsed-dye laser treatment

“…In atopic eczema, where a decreased skin barrier is one factor leading to an increased incidence of viral, fungal and bacterial infections, molluscum contagiosum infections appear to occur more frequently and also to be more widespread 10 . There are case reports of eczematous skin occurring within a PWS, 11 as well as of eczematous skin changes occurring as a result of treatment with the PDL 12 . These causes of a reduced skin barrier function as a consequence of eczematous skin changes have to be considered as further possibilities of the disease mechanism leading to infection in our patient, but they were not clinically apparent.…”

Port‐Wine‐Stain–Associated Dermatitis: Implications for Cutaneous Vascular Laser Therapy

“…Although the adverse effects associated with PDL therapy are rarely serious, they are not insignificant. Short‐term adverse effects may include erythema, edema, and crusting of the treated area, as well as bullae and local infection in rare occurrences (10,25). In addition, instances of PDL therapy inducing eczematous lesions in PWS, wherein patients develop pruritic scaly eruptions, consistent with spongiotic dermatitis on histologic examination, weeks after being treated with PDL, have been reported (9,10).…”

“…Of interest, treatment of PWS with pulsed dye laser (PDL) therapy has been reported to produce lasting improvement or resolution of the overlying dermatitis, in addition to lightening the appearance of the congenital vascular malformation (5,6,8). However, in rare instances, PDL therapy may precipitate an eczematous dermatitis over an otherwise uncomplicated PWS (9,10).…”
