Squamoid Eccrine Ductal Carcinoma: Case Series of a Rare, Potentially Aggressive Skin Cancer Associated With Immunosuppression

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Squamoid Eccrine Ductal Carcinoma (SEDC) is a rare cutaneous adenexal carcinoma first described in 1997. It has distinct biphasic features on histology which commonly result in misdiagnosis as Bowen disease or cutaneous squamous cell carcinomas (cSCC) if diagnostic skin biopsies are too superficial. This may lead to a delay in diagnosis. It is

Clonal identification and homology differentiate primary central nervous system lymphoma from non-central nervous system lymphoplasmacytic lymphoma: a case report

Journal of Medical Case Reports
Background Lymphoplasmacytic lymphoma/Waldenström macroglobulinemia rarely transforms into diffuse large B-cell lymphoma, and there have been no reports of cases proving clonal identity when presenting as primary central nervous system lymphoma.

Lymphoplasmacytic lymphoma relapse presenting as isolated multifocal subcutaneous adipose tissue infiltrates on 18F-FDG PET/CT

Acta Radiologica Open, 2023
Lymphoplasmacytic lymphoma (LPL)/Waldenström macroglobulinemia (WM) is an uncommon mature B cell lymphoma usually involving the bone marrow and, less commonly, the spleen and/or lymph nodes.

Cutaneous amyloidosis as the first presentation of Waldenstrom macroglobulinemia

Caspian Journal of Internal Medicine, 2020
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 ...

Increased glutathione utilization augments tumor cell proliferation in Waldenstrom Macroglobulinemia

Redox Biology, 2020
Metabolic reprogramming is a hallmark of cancer cells. In Waldenstrom Macroglobulinemia (WM), the infiltration of IgM-secreting lymphoplamacytic cells into the bone marrow (BM) could shift the homeostasis of proteins and metabolites towards a permissive ...

Clinical and Laboratory Characterization of Acquired Von Willebrand Syndrome

American Journal of Hematology, Volume 101, Issue 9, Page 2147-2156, September 2026.
ABSTRACT Acquired von Willebrand Syndrome (AVWS) is a rare bleeding disorder characterized by quantitative or qualitative defects of von Willebrand factor (VWF) in patients without a personal or family history of bleeding. It is frequently associated with systemic diseases, particularly lymphoproliferative disorders (LPDs) and myeloproliferative ...

Current approach to Waldenström Macroglobulinemia

Cancer Treatment and Research Communications, 2022
Waldenström Macroglobulinemia (WM) is a unique, low grade, IgM lymphoplasmacytic lymphoma with a heterogeneous clinical course. A paucity of high-grade evidence from large phase 3 trials remains a major issue in the field despite a rapidly expanding ...

Cumulative Antigen Suppression Reduces Clonal Plasma Cell Evolution in Gaucher Disease

American Journal of Hematology, Volume 101, Issue 9, Page 2197-2213, September 2026.
ABSTRACT Chronic antigenic stimulation is implicated in the pathogenesis of monoclonal gammopathy and multiple myeloma, yet longitudinal human evidence linking sustained antigen exposure to modifiable clonal plasma cell evolution remains limited. Gaucher disease (GD), caused by biallelic GBA1 pathogenic variants, is characterized by accumulation of ...
