Immunoglobulin M monoclonal gammopathy is detected in Waldenström macroglobulinemia (WM), a rare lymphoplasmacytic lymphoma with serum immunoglobulin M. We report three rare presentations with focus on diagnostic and management challenges of type I cryoglobulinemia, type II cryoglobulinemia, and Bing-Neel syndrome. In approximately 10% of WM cases, macroglobulins can precipitate to cryoglobulins. Type I and II cryoglobulinemia, representing 10-15% and 50-60% of WM cases, respectively, present with vasculitis and renal failure. Bing-Neel syndrome, representing 1% of WM patients, is a rare neurological complication with lymphoplasmacytic infiltration in the brain. WM diagnosis includes bone marrow biopsy, immunophenotypic analysis, and L265P mutation. We initiated management of cryoglobulinemia with dexamethasone, rituximab, and cyclophosphamide; in Bing-Neel, bortezomib and dexamethasone, followed by a Bruton tyrosine kinase inhibitor.

: Cryoglobulinemia (CG) syndrome is a heterogeneous condition characterized by the presence of cryoglobulins in serum, often leading to vasculitis with protean clinical manifestations. Understanding the presentation of cryoglobulinemia-related symptoms based on cryoprecipitate levels, GC type, and severity at diagnosis is essential for effective management. Hence, this study aimed to provide a comprehensive analysis of patients with positive cryoglobulin detection to investigate these aspects.

Primary Raynaud's phenomenon (RP) is a common and self-limiting condition, which is not secondary to any other disease process. In contrast, secondary RP has an underlying etiology. Several conditions can lead to secondary RP, which creates a challenging landscape for clinicians.

A 60-year-old male was admitted from the emergency department with extensive leg ulcers and polyarticular joint pain. Cryocrystalglobulinemia was diagnosed through positive cryoglobulin studies and characteristic histopathological findings. Treatment with bortezomib led to complete clinical resolution.

Marginal zone lymphoma (MZL) of the lung is an indolent B-cell lymphoma. The peripheral blood of most patients with pulmonary MZL contains low or undetectable monoclonal immunoglobulin (M protein) levels. In this case, the clinical laboratory discovered that the pulmonary MZL patient not only associated with high concentration of monoclonal IgG-type protein but also exhibited obvious gel formation characteristics that interfered with clinical biochemistry tests.
