Necrobiosis lipoidica diabeticorum treated with the pulsed dye laser

BACKGROUND AND OBJECTIVE : Different treatment modalities have been advocated for necrobiosis lipoidica diabeticorum but clinical response is unpredictable. The purpose of this study was to evaluate the usefulness of pulsed dye laser (Candela SPTLÁ, Irvine, MA, USA) in the treatment of an area of necrobiosis lipoidica of 4 cm in diameter on the anterior aspect of the leg in a non-diabetic patient. MATERIALS AND METHODS : A spot test was made at 6.0, 6.5 and 7.0 J/cm 2 energy fluences and the best energy fluence was selected after a 2-month postoperative evaluation. The patient received three treatment sessions with a fluence of 6.5 J/cm 2 , 585-nm wavelength, 5-mm spot size, and 450 µs pulse duration at 8-week intervals. The patient was given routine skin care advice with emollient cream and sunscreen (SPF 15) until the following session. RESULTS : Overall cosmetic improvement was achieved, with a decrease of erythema and telangiectasis, and stabilization in terms of progression (size) in the left half of the lesion, with no modification of atrophy or pigmentary changes. The right upper quadrant of the lesion showed an erythematous peripheral halo with minimal reduction in the erythema and telangiectasia, and discrete size increase. CONCLUSION : Pulsed dye laser may be a useful treatment for improving the telangiectasia and erythematous component of necrobiosis lipoidica.     

Pulsed dye laser treatment of necrobiosis lipoidica: report of a case

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.     

The long-term effect of pulsed dye laser on Necrobiosis Lipoidica: A case study

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.     

类脂质渐进性坏死的研究进展

类脂质渐进性坏死是发生在真皮结缔组织的疾病,以小腿胫前的硬皮病样斑块为临床特征.其确切的发病机制不清楚,可能与糖尿病、免疫机制、胶原变性、血小板异常及创伤等多种因素有关.类脂质渐进性坏死同前尚无有效的治疗方法,糖皮质激素、免疫治疗、抗肿瘤坏死因子药物、光疗、延胡索酸酯及外科手术等有一定的疗效.

患者女,32岁,因双侧小腿胫前斑块3年余就诊。患者3年前被蚊虫叮咬后左腿局部起丘疹,轻微瘙痒,以后双侧小腿逐渐出现丘疹并逐渐扩大,形成中央轻度凹陷的硬化萎缩性黄色斑块,自行外用多种糖皮质激素药膏无好转,平素身体健康,其母亲有糖尿病史……     

Generalized destructive, ulcerating and debilitating necrobiosis lipoidica sine diabetes in a young male recalcitrant to therapy

We present the case of a 26-year-old Caucasian male with an ulcerative necrobiosis lipoidica (NL) affecting approximately 30% of the skin including the scalp and face. The disease started at (he age of six and has progressed constantly since then. Over the last 20 years no diabetes mellitus or diabetic disposition was found. Up to now all treatments, e.g. oral corticosteroids and pentoxifylline have failed to stop the progression of the disease. To the best of our knowledge this is the most extensive case of NL described so far.
