Background: Klinefelter syndrome is considered one of the most common sex chromosome disorders affecting males. The presence of an extra X chromosome can alter the tendency to develop various cancers, including lymphomas. Lacrimal gland lymphoma is a disease of the elderly, with a median age of presentation of 70 years.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL) is an indolent B-cell lymphoma that can involve various anatomic sites. EMZL is derived from post-germinal center marginal zone B cells and typically lacks bcl-6 expression. Herein, we report two post-treatment cases of EMZL where unexpected bcl-6 protein expression was observed in specimens obtained following recurrence or progression.

Primary thyroid lymphomas comprise largely extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL) and diffuse large B-cell lymphoma (DLBCL), followed by follicular lymphoma (FL). They commonly develop from a background of Hashimoto's thyroiditis (HT), where dysregulated immune responses trigger autoreactive infiltrates and drive clonal B-cell evolution. To understand how these lymphomas and their relapse evolve, we investigated 10 cases by mutation profiling, including five with metachronous lymphomas [primary lymphoma (EMZL = 4, DLBCL = 1) with local relapse (EMZL = 3, DLBCL = 2)], one composite EMZL and Epstein-Barr virus (EBV)-positive DLBCL, and four lymphomas (EMZL = 3, FL = 1) with prior or subsequent biopsy showing HT.

Objectives: We investigate if sublingual space invasion (SLI) determined on magnetic resonance imaging confers differences in clinicopathological manifestations and treatment outcomes of oral tongue squamous cell carcinoma (OTSCC).
Study Design: Retrospective cohort study.
Setting: Tertiary Academic Medical Center.

Aims: The diagnosis of lymphoplasmacytic lymphoma (LPL) in the bone marrow (BM) is challenged by aberrant phenotypes and by overlapping histological features with marginal zone lymphoma (MZL). To address these issues, we (i) assessed LPL immunophenotype on a large series of BM samples, (ii) drew possible correlations between LPL phenotype and clinical/molecular data and (iii) investigated the role of new phenotypical markers in the differential diagnosis between LPL and MZL.
Materials And Methods: The study retrospectively considered 81 clinically annotated LPL diagnosed at Padua University Hospital (Padua, Italy) during a 5-year period.
