Sclérœdème de Buschke chez un diabétique : traitement par immunoglobulines intraveineuses

[Differential diagnosis of sclerosing skin diseases: scleredema adultorum of Buschke]

Scleredema adultorum of Buschke is an important differential diagnosis in sclerosing diseases. Diagnosis is based on the typical histology with mucin deposits and grossly increased dermal width and a clinical presentation of diffuse non-pitting induration of the skin starting at the nape of the neck and interscapular region extending to shoulders and upper thorax, causing dysmobility due to dermal stiffness. Even though the pathogenesis remains unclear, three subtypes can be distinguished: association with infections, paraproteins, or most frequently with diabetes mellitus. Management of the disease includes physiotherapy, physical therapies such as ultraviolet (UV) or ionizing irradiation, intravenous immunoglobulins and interdisciplinary treatment directed at associated diseases. Optimizing diabetes therapy and thereby decreasing insulin use may confer significant improvement.

[Buschke's scleredema successfully treated with extracorporeal photopheresis]

BACKGROUND

Scleredema adultorum (Buschke's scleredema) is a cutaneous mucinosis of unknown origin, clinically characterized by a diffuse induration of the skin usually involving the neck, shoulders and back, which limits patients' mobility.

CASE REPORT

We report a case of a 50-year-old woman who presented a chronic sclerodermiform syndrome for 2 years associated with type 1 diabetes. Physical examination revealed an extensive skin induration involving the shoulders, neck and back. Histologic examination confirmed the diagnosis of scleredema adultorum. The patient was treated with extracorporeal photopheresis (EPP) twice a month for two months. At follow-up, mobility was highly improved after two months. Beneficial effect of EPP was maintained on the long term while sessions were spaced.

DISCUSSION

EPP is an unconventional treatment of Buschke's scleredema. We described a case of Buschke's scleredema successfully treated with EPP which may represent a therapeutic option for the treatment of scleredema.

Diabetes mellitus and the skin

Several dermatoses are routinely associated with diabetes mellitus, especially in patients with chronic disease. This relationship can be easily proven in some skin disorders, but it is not so clear in others. Dermatoses such necrobiosis lipoidica, granuloma annulare, acanthosis nigricans and others are discussed in this text, with an emphasis on proven link with the diabetes or not, disease identification and treatment strategy used to control those dermatoses and diabetes.

Scleredema. A multicentre study of characteristics, comorbidities, course and therapy in 44 patients

BACKGROUND

The prognostic and therapeutic features of scleredema are poorly documented.

OBJECTIVES

To describe the characteristics of patients with scleredema regarding demographics, clinical characteristics, comorbidities, therapeutic interventions and course.

METHODS

We conducted a retrospective multicentre study.

RESULTS

We identified 44 patients (26 men).The mean age at diagnosis was 53.8 years. The most common associated disorders were endocrine/metabolic diseases including 30 patients suffering from diabetes, mostly type 2 diabetes. Monoclonal gammopathies were confirmed in five cases. A preceding respiratory tract infection was not a feature. Treatments with different combination or sequential modalities were used with variable results. Phototherapy (UVA1 or PUVA) was the treatment associated with higher, although partial response. Systemic corticosteroids and immunosuppressive drugs were reserved to patients with severe disease in whom phototherapy had failed or for patients with multiple myeloma. Forty-one patients were followed up (mean period: 32.2 months).Thirty-nine patients are alive, 30 with and 9 without skin disease. Two patients died of cardiovascular complications due to myeloma and severe diabetes.

CONCLUSIONS

Scleredema is a chronic debilitating disease associated with diabetes and metabolic syndrome, unresponsive to various treatments but not necessarily a life-threatening condition. Although there is no definitive treatment, phototherapy should be attempted first. Treatment of primary disease including strict glycaemic control combined with physical therapy should be also employed.

The skin landscape in diabetes mellitus. Focus on dermocosmetic management

Background

Some relationships are established between diabetes mellitus (DM) and a series of cutaneous disorders. Specific dermatoses are markers for undiagnosed DM. Other disorders represent supervening complications in an already treated DM patient.

Objective

To review the information about dermocosmetic care products and their appropriate use in the management and prevention of dermatoses related to DM.

Method

The peer-reviewed literature and empiric findings are covered. Owing to the limited clinical evidence available for the use of dermocosmetics, a review of the routine practices and common therapies in DM-related dermatoses was conducted.

Results

Some DM-related dermatoses (acanthosis nigricans, pigmented purpuric dermatosis) are markers of macrovascular complications. The same disorders and some others (xerosis, Dupuytren’s disease) have been found to be more frequently associated with microangiopathy. Other skin diseases (alopecia areata, vitiligo) were found to be markers of autoimmunity, particularly in type 1 DM. Unsurprisingly, using dermocosmetics and appropriate skin care has shown objective improvements of some DM-related dermatoses, such effects improve the quality of life. The most common skin manifestations of DM fall along continuum between “dry skin,” xerosis, and acquired ichthyosis, occurring predominately on the shins and feet. Dermocosmetic products improve the feeling of well-being for DM patients.
