Cutaneous amyloidosis as the first presentation of Waldenstrom macroglobulinemia
Authors
Abstract:
Background: Waldenstrom macroglobulinemia is a lymphoplasmacytic lymphoma with elevated serum immunoglobulin M and multi-organ involvement. Primary systemic amyloidosis usually develops due to immunoglobulin light chains depositions in different organs due to an underlying gammopathy. Case presentation: Our patient was an 86-year-old man with macroglossia, ecchymotic patches and bullous lesions associated with a skin laxity on the periorbital, palmar, and glans penis areas. Skin biopsy confirmed dermal amyloid depositions. In serum immunofixation electrophoresis, prominent monoclonal immunoglobulin-M lambda light chains were detected associated with prominent lymphoplasmacytic infiltration in bone marrow biopsy which was diagnosed as Waldenstrom macroglobulinemia. Conclusions: Skin involvement presenting as cutaneous amyloidosis could be the first manifestation of Waldenstrom macroglobulinemia. We should think about an underlying gammopathy in an old patient with skin laxity and ecchymosis

Proteomic analysis of waldenstrom macroglobulinemia.
To better understand the molecular changes that occur in Waldenstrom macroglobulinemia (WM), we employed antibody-based protein microarrays to compare patterns of protein expression between untreated WM and normal bone marrow controls. Protein expression was defined as a >2-fold or 1.3-fold change in at least 67% of the tumor samples. Proteins up-regulated by >2-fold included Ras family protein...

Waldenstrom macroglobulinemia (WM) is a B-cell lymphoplasmacytic lymphoma characterized by monoclonal immunoglobulin M protein in the serum and infiltration of bone marrow with lymphoplasmacytic cells. Asymptomatic patients can be observed without therapy. First-line therapy should consist of the monoclonal anti-CD20 antibody, rituximab, given typically in combination with other agents. We pref...

Waldenström's Macroglobulinemia (WM) is a B-cell disorder characterized by the infiltration of the bone marrow (BM) with lymphoplasmacytic cells, as well as detection of an IgM monoclonal gammopathy in the serum. WM is considered an incurable disease, with an overall median survival of only 5-6 years. The success of targeted therapy in multiple myeloma (MM) has led to the development and invest...

Pts were treated with 4 courses of 2-CDA (0.1 mg/kg sc for 5 days) in combination with Rituximab at standard schedule. Relative quantitation was performed using the Delta CT calculation: the value of gene expression was normalised to the calibrator (healthy tissue cells). Results. Clinical responses were evaluated according to Response Criteria (3 International Workshops on WM) 2 months after t...
