The combination of bortezomib and dexamethasone is an efficient therapy for relapsed/refractory scleromyxedema: A rare disease with new clinical insights

Abstract:

Scleromyxedema (SM) is a rare primary cutaneous inflammatory mucinosis characterised by papular mucinosis, monoclonal gammopathy and extracutaneous involvement. Most therapeutic options have failed in SM but high-dose therapy followed by autologous peripheral blood stem cell transplantation (APBSCT) appears to be highly effective, although SM normally relapses. We report the case of a 29-yr-old patient with severe SM who achieved stringent complete response with Bortezomib plus Dexamethasone after an early relapse subsequent to a high-dose melphalan regimen followed APBSCT. It is of particular note that dermatological lesions responded to both therapies before M-component modifications, suggesting that SM is independent of M-component characteristics. However, treatment should be directed towards the underlying plasma cell malignancy with typical anti-myeloma agents. © 2012 John Wiley & Sons A/S.
