Successful UVA1 phototherapy in a patient with scleredema adultorum

Scleroedema of Buschke in conjunction with ovarian carcinoma: rare association of a rare disease

Scleroedema is a rare clinical condition characterised by diffuse woody induration of skin commonly associated with diabetes mellitus, infections and monoclonal gammopathy. Its association with ovarian malignancy has not been reported. We report a case of a 56-year-old female with rapidly progressing skin thickening of limbs, face and trunk for 1 year and abdominal distension for 3 months. Patient had thickened skin, mask-like facies and ascites on examination. Atypical cells were seen in ascitic fluid. Contrast-enhanced computerised axial tomography scan of abdomen was suggestive of ovarian malignancy. Markers for autoimmune disorders were negative. CA 125 was elevated. Other causes of sclerodermiform-like syndrome were ruled out. Histopathology of skin biopsy was definitive of scleroedema. Diagnosis of scleroedema associated with ovarian malignancy was made based on temporal association, exclusion of other causes and histopathological findings. To our knowledge this is the first reported case of scleroedema associated with ovarian tumour.

[Scleredema adultorum : Clinical presentation, diagnostic workup, differential diagnosis, treatment option]

Scleredema adultorum (SA) is a rare scleromucinous disease of unknown etiology that characteristically leads to wodden induration located on the neck and upper trunk. Three types of SA can be distinguished according to the association with pre-existing or underlying disease: SA in association with infections (mostly streptococcal infections of the upper respiratory tract), SA in association with monoclonal gammopathy, and SA in association with diabetes. The clinical findings, extent of disease, and course substantially differ depending on the subtype of SA. Spontaneous regression often occurs in infection-associated SA, whereas patients with diabetes or monoclonal gammopathy usually show a chronic progressive course of disease. Phototherapy and methotrexate are the current recommended first-line treatments for SA, clinical improvement often takes several months, and treatment failure is frequent. Physiotherapy should be offered in all types of SA in order to improve motility.

S1-Leitlinie zur UV-Phototherapie und Photochemotherapie

Die heilsame Wirkung des Sonnenlichts war teilweise schon im Altertum bekannt und fand in der zweiten Hälfte des 19. Jahrhunderts wieder zunehmend Beachtung. Den Beginn der modernen Phototherapien markiert die Entwicklung einer Apparatur zur ultravioletten Bestrahlung der Hauttuberkulose durch Finnsen zu Beginn des zwanzigsten Jahrhunderts. Zur Therapie von Hauterkrankungen finden beinahe ausschließlich die spektralen Bereiche unterhalb des sichtbaren Lichtes (ultraviolett) Anwendung. Seit den 1970er Jahren stehen zunehmend leistungsfähige künstliche Strahlenquellen bereit für die Therapie mit UVB, UVA und die Kombination von UVA mit Photosensibilisatoren (Photochemotherapie). Hohe strukturelle und prozedurale Qualitätsstandards sind unabdingbare Voraussetzung für die Durchführung einer gleichermaßen wirkungsvollen wie auch sicheren Phototherapie. Die Leitlinie formuliert den aktuellen Konsens führender Experten auf dem Gebiet der Phototherapie in Bezug auf die Indikationen für die jeweiligen Therapieverfahren, deren Gegenanzeigen und Nebenwirkungen und insbesondere für die Wahl der korrekten Dosis zu Beginn und im Verlauf einer Therapie sowie das Management von Nebenwirkungen.

UVA-1 therapy of localized scleroderma and other diseases accompanied by skin sclerosis

The study results confirm the efficacy of the UVA-1 therapy for patients with localized scleroderma, extragenital lichen sclerosus et atrophicus, sclerodermatous chronic graft-versus-host disease and scleredema adultorum. The therapy has an anti-inflammatory and anti^m^ action, arrests progression and reduces the activity of the disease process, and has a good efficacy and safety profile.

Skin signs in diabetes mellitus

Diabetes mellitus is the most common endocrine disorder with continuously increasing prevalence. Blood vessels, nerves, eyes, kidneys and skin are affected, which causes both an enormous financial burden and a reduced quality of life of the affected patients. Long-standing diabetes may impair skin homeostasis resulting in skin manifestations in at least one third of all diabetics. The skin involvement may be the first presenting sign of diabetes, thus the respective skin signs should lead to diabetes focused diagnostic. Besides, the skin signs may be considered as a marker for the course of the disease or for the success of therapeutic interventions.

Ultraviolet A phototherapy for sclerotic skin diseases: a systematic review

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.

Scleroderma-like fibrosing disorders

Many conditions presenting with clinical hard skin and tissue fibrosis can be confused with systemic sclerosis (scleroderma). These disorders have very diverse etiologies and often an unclear pathogenetic mechanism. Distinct clinical characteristics, skin histology, and disease associations may allow one to distinguish these conditions from scleroderma and from each other. A prompt diagnosis is important to spare patients from ineffective treatments and inadequate management. This article highlights nephrogenic systemic fibrosis (nephrogenic fibrosing dermopathy), eosinophilic fasciitis (Shulman's syndrome), scleromyxedema, and scleredema. These often are detected in the primary care setting and referred to rheumatologists for further evaluation. Rheumatologists must be able to promptly recognize them to provide valuable prognostic information and appropriate treatment options for affected patients.
