CD79B and MYD88 Mutations in Splenic Marginal Zone Lymphoma

CD79B and MYD88 Mutations in Splenic Marginal Zone Lymphoma

The mutation status of genes involved in the NF-κB signaling pathway in splenic marginal zone lymphoma was examined. DNA sequence analysis of four genes was performed: CD79A, CD79B, CARD11, and MYD88 that are activated through BCR signaling or Toll-like and interleukin signaling. A single point mutation was detected in the CD79B gene (Y196H) in one of ten SMZL cases. Additionally, one point mut...

Splenic marginal zone lymphoma.

Splenic marginal zone lymphoma (SMZL) is a specific low-grade small B-cell lymphoma that is incorporated in the World Health Organization classification. Characteristic features are splenomegaly, moderate lymphocytosis with villous morphology, intrasinusoidal pattern of involvement of various organs, especially bone marrow, and relative indolent course. Tumor progression with increase of blasti...

Surgical management of splenic marginal zone lymphoma.

OBJECTIVES Splenic marginal zone lymphoma (SMZL) is a rare indolent B-cell lymphoma with variable prognosis. As a result, there is sparse knowledge on the role of splenectomy and best management approaches. We aim to explore management strategies and outcomes amongst the cohort of SMZL patients at our centre. METHOD A retrospective review of all splenectomies performed at a tertiary referral ...

Unusual Course of Splenic Marginal Zone Lymphoma

A 53-year-old woman was diagnosed with splenic marginal zone lymphoma by pathological examination on left submandibular lymph node and bone marrow biopsies and markedly enlarged spleen. Four cycles of Rituximab chemotherapy were given. Seven months after finishing Rituximab chemotherapy, she developed left upper extremity swelling without evidence of deep venous thrombosis. Repeat PET/CT scan d...
