Scleroderma circumscripts juvenile
HistoryThis section has been translated automatically.
In childhood, linear or band-shaped variants - type II- predominate (see below scleroderma, circumscripts). ..
Occurrence/EpidemiologyThis section has been translated automatically.
The linear form at the extremities is represented with 65%, the plaque type with 26%, the generalized form with 7%, the deep circumscribed scleroderma with 2%.
EtiopathogenesisThis section has been translated automatically.
The blame lies with trauma, infections, genetic factors (about 10% of patients have a positive family history of rheumatic and autoimmunological diseases) and embryonic developmental disorders (formation of an epigenetic cutaneous mosaic)
LocalizationThis section has been translated automatically.
About 20% of children suffer from linear circumscritic scleroderma of the head (type "en coup de sabre" as well as the rare progressive facial hemiatrophy).
Clinical featuresThis section has been translated automatically.
Linear circumscritic scleroderma of the en coup de sabre type and progressive facial hemiatrophy occur almost exclusively in early childhood. Unlike the other subtypes of circumscritic scleroderma, the course is slowly insidious and the active phase of the disease is usually much longer. Neurologic symptoms are common and may take the form of epileptic seizures, headaches, behavioral disturbances, and learning disabilities. Histologically, localized gliosis areas as well as perivascular inflammatory infiltrates could be found. Ophthalmologic changes are varied: uveitis, ocular muscle dysfunction, loss of eyebrows or alterations of the eyelids.
Juvenile linear circumscritic scleroderma of the extremities is characterized by a much more severe course than that of adults. It often results in skin and muscle atrophy, contractures of affected joints, shortening of extremities, and circumferential reductions. This often results in considerable functional, cosmetic and also psychological limitations in the affected patients. Furthermore, arthralgias and arthritides of the affected extremity are reported.
Disabling pansclerotic morphea, a very rare special form of generalized circumscritic scleroderma, usually manifests before the age of 14; rapid disease progression with obligate involvement of extracutaneous structures (subcutaneous adipose tissue, muscle, and bone) with severe growth retardation are the clinical features.
The limited form (mostly plaque type), the deep form (see below scleroderma, circumskripte) as well as eosinophilic fasciitis run a similar course as in adults.
LaboratoryThis section has been translated automatically.
In the generalized form, eosinophilia can occur in the active stage. In the linear forms, a positive rheumatoid factor, increased inflammatory parameters (BSG; CRP) and hypergammaglobulinemia may be present in the active phase of the disease. ANA often show a homogeneous pattern in the linear forms. ENA is usually missing.
Complication(s)This section has been translated automatically.
Organ infestation is very rare; the literature is contradictory (lungs: 2-3%, heart:1%, kidney:1%). Therefore no corresponding organ diagnosis is required.
TherapyThis section has been translated automatically.
- In active linear circumscript scleroderma, an efficient systemic therapy should be initiated at the earliest possible time to stop the progression of the disease (avoidance of contractures, limb malpositions). This statement also applies to large circumscribed scleroderma.
- Accompanying physiotherapy (physiotherapy, manual lymph drainage) is important. Orthopaedic interventions (e.g. surgical corrections such as Achilles tendon lengthening or epiphysiodesis on the healthy leg to adjust a leg length difference) should only be carried out in the longer existing inactive stage of the disease.
- Cosmetic-aesthetic corrections in linear circumscript scleroderma of the type en coup de sabre and in progressive facial hemiatrophy are only advisable in the case of prolonged inactivity of the disease.
