[Sclerodermiform chronic graft-versus-host disease after allogenic peripheral blood stem-cell transplantation]. / Sklerodermiforme chronische Graft-versus-Host-Erkrankung nach allogener peripherer Blutstammzelltransplantation.

HISTORY AND CLINICAL FINDINGS: A 46-year-old man presented with suberythrodermia and an acral-accentuated sclerosis, which had been progressing over the past 6 months, with extensive, painful ulcers within the sclerotic areas of the calf. Due to acute myelotic leukemia (AML), an allogenic peripheral blood stem-cell transplantation with subsequent immunosupression with mycophenolatmofetil (MMF) and ciclosporin A had been performed 8 years previously. The patient had discontinued treatment on his own after about 2 years, having suffered a cerebroischemic insult in the meantime. INVESTIGATIONS: Histological examinations revealed sclerodermatous changes. Titres of antinuclear antibodies were unremarkable. Laser-Doppler-flowmetry also indicated an active inflammatory and sclerosing process. FACS analysis of the peripheral blood did not reveal signs of AML recurrence. DIAGNOSIS, THERAPY AND COURSE: The histological pattern in conjunction with the anamnesis indicated a cutaneous chronic graft-versus-host disease (GvHD). No further organ involvement was observed. The MMF therapy which the patient had discontinued was restarted. In addition, PUVA therapy was initiated. These measures and intensive physiotherapeutic exercises in parallel prevented further progression of the sclerosis and secondary mobility limitations. The ulcers healed completely with pentoxifylline and anti-infective treatment. CONCLUSION: After stem-cell transplantation, early diagnosis of GvHD is especially important due to possible irreversible sclerodermatous changes and other organ manifestations. Also for this reason, strict clinical follow-up is especially important with respect to compliance and efficacy of the immunosuppression.

[Primary cutaneous manifestation of Wegener's granulomatosis]. / Primär kutane Manifestation einer Wegener-Granulomatose.

HISTORY: A 57-year-old man was admitted with hemorrhagic papules and necrotising nodules on both elbows and upper legs. Recurrent arthralgia occurred. INVESTIGATIONS: The skin biopsy showed a cutaneous necrotising vasculitis. Positive test results for c-ANCA and proteinase 3 antibodies and a slightly increased WBC and a mild proteinuria were noticeable. DIAGNOSIS, TREATMENT AND COURSE: The diagnosis of an early systemic Wegener's granulomatosis was based on elevated proteinase 3-titres and cutaneous histologic findings as necrotising vasculitis and granulomatous inflammation. Treatment with prednisolone followed by methotrexate resolved the cutaneous symptoms and the arthralgia completely. Three months later the patient developed a progredient methotrexate toxicity caused by a glomerulonephritis. CONCLUSION: Wegener's granulomatosis should be considered if a cutaneous necrotising vasculitis is diagnosed. A cutaneous manifestation could be an early symptom. Methotrexate could be used for treatment of mild courses of Wegener's disease without renal involvement.
