RESUMO

A 57-year-old female was presented with an irrepressible case of Necrobiosis Lipoidica considering the possibility of a surgical skin graft. Instead, a pulsed dye laser treatment was used as an alternate treatment. Previous case studies have been found in the literature on the effect of pulsed dye laser on Necrobiosis Lipoidica. The use of a pulsed dye laser in this case resulted in rendering the lesions asymptomatic for pain and a reduction in volume. Prolonged control was exhibited. From this case, we conclude that pulsed dye laser therapy is effective when increasing the number of treatments of laser therapy, and can be used as a treatment for Necrobiosis Lipoidica.

RESUMO

We report on a 52-year-old female patient with chronic, ulcerating necrobiosis lipoidica (NL) who dramatically responded to ultraviolet A1 (UVA1) phototherapy. The patient had NL on her right shin for more than 30 years without evidence of diabetes mellitus. Treatment with a variety of local and systemic agents failed to prevent progression into ulceration, which necessitated repeated surgical interventions in the past. When the patient presented again with torpid ulcers at the periphery of previously grafted skin, high-dose UVA1 phototherapy was initiated. Improvement occurred rapidly and after 22 irradiations and a total exposure dose of 1480 J/cm², the ulcers had healed completely. During a follow-up period of 6 years,two minor recurrences were successfully retreated with UVA1 phototherapy.

RESUMO

BACKGROUND: Ultraviolet (UV) A-1 phototherapy is now available for a variety of skin diseases. Increasingly since 1995, there have been investigations of the efficacy of UVA-1 (340-400 nm) therapy for sclerotic skin diseases. Most studies undertaken treated patients who had localized scleroderma, but UVA-1 phototherapy is currently also used for other sclerotic skin conditions. OBJECTIVE: We sought to assess the efficacy, biological effects, and side effects of UVA-1 in a variety of sclerotic skin diseases (localized scleroderma, eosinophilic fasciitis, chronic graft-versus-host disease, lichen sclerosus et atrophicus, scleredema adultorum, necrobiosis lipoidica, POEMS disease, pansclerotic porphyria cutanea tarda, and drug-induced scleroderma-like disorders). METHODS: The authors searched for publications dated between January 1996 and November 2007 in the computerized bibliographic database, PubMed. PubMed was searched using medical subject heading terms and open searches to retrieve the latest reports. RESULTS: The evidence based on research concerning the effect of full-spectrum UVA (320-400 nm) and UVA-1 on these skin diseases is still growing, and appears promising. Up until now, good results are shown for all different doses (low, medium, and high) UVA-1 and UVA. There are insufficient data regarding use of high-dose UVA-1 and there are no comparative studies to make a clear assessment regarding the superiority of low-, medium-, or high-dose UVA-1 therapy. Although UVA-1 has various effects on, for instance, fibroblasts and inflammatory cells, the precise mode of action remains obscure. The main short-term side effects of UVA-1 therapy are erythema, pruritus, xerosis cutis, tanning, and recrudescence of herpes simplex infection. More studies are warranted to investigate the potential long-term risk of photoaging and skin cancer. Currently, UVA-1 is considered to be less carcinogenic than psoralen plus UVA (PUVA). LIMITATIONS: Because of the limited availability of randomized controlled trials and large cohort studies, it is difficult to draw firm conclusions on the long-term efficacy, optimum dose, and best treatment regimens for UVA-1 when administered to patients with sclerosing skin disorders. CONCLUSIONS: Full-spectrum UVA and UVA-1 phototherapy seem effective in the treatment of sclerotic skin diseases based on data retrieved from the literature. UVA-1 treatment can shorten the active period of localized scleroderma and pseudoscleroderma and prevent further disease progression, including contractures. Further investigations will be needed to determine any additional biological effects of UVA-1. Although long-term side effects are not yet known, UVA-1 might develop into a promising beneficial and well-tolerated treatment in the therapeutic armamentarium for sclerotic skin diseases. Long-term studies in large groups of patients are clearly needed.

RESUMO

A 23-year-old woman with long-standing insulin dependent diabetes presented with necrobiosis lipoidica. She was particularly troubled by the telangiectatic element of the lesion and therefore underwent test treatment with the pulsed dye laser. At low fluences minimal therapeutic effect was achieved, and at higher fluences skin breakdown occurred. This resolved with conservative management. It would appear that caution is required when attempting to treat necrobiosis lipoidica with laser.
