Clinical, Pathologic, and Molecular spectrum of Angioinmmunoblastic T-cell Lymphoma Cutaneous Lesions: Clinical, Pathologic, and Molecular Analysis.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive malignancy that frequently presents with extranodal involvement. Cutaneous tropism is clinically and histopathologically variable, which may pose a diagnostic challenge. We conducted a retrospective analysis of 40 samples of 20 cases of cutaneous AITL, focusing on the clinicopathologic and molecular correlations between skin and lymph node (LN) samples.

In reference to our paper published in the August issue 2020 of Haematologica,1 the sentence "funded by the European Union Next Generation EU, funds that finance the actions of the Recovery and Resilience Mechanism (RRM)" in the Funding was missing. We need to add it to justify the project. So the Funding paragraph should read as follows: Funding: this work was supported by grants from the Instituto de Salud Carlos III (ISCIII) of the Spanish Ministry of Economy and Competence, co-funded by European Union (FEDER) (ERDF/ESF, "A way to make Europe"/"Investing in your future" (MINECO, ISCIII) funded by the European Union Next Generation EU, funds that finance the actions of the Recovery and Resilience Mechanism (RRM) (Plan Nacional I+D+I: PI17/02172, PI21/01724, 15826/004, 41163/005 and PMP21/00015), AECC, the Madrid Autonomous Community and STARTUP2020/L2566.

Different Mutational Profiles of Subcutaneous Panniculitis-like T-cell Lymphoma and Lupus Panniculitis: An Additional Case Series.

Background: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare cytotoxic T-cell lymphoma with indolent behavior, mostly present in women and associated with immunological diseases whose pathogenic background is still poorly understood. SPTCL is associated with lupus erythematosus panniculitis (LEP) and histologically misdiagnosed.

Objectives: The aim of our study was to identify mutations affecting the pathogenesis of both SPTCL and LEP.

Intraparenchymal low-grade B-cell lymphomas of the central nervous system: Clinicopathologic and molecular analysis of three cases and a review of the literature.

Primary central nervous system (CNS) lymphomas represent 1 % of all non-Hodgkin lymphomas, with diffuse large B-cell lymphomas as the prevailing subtype. Low-grade B-cell lymphomas are exceptional with only 24 marginal zone B-cell lymphomas (EMZL) and 1 follicular lymphoma (FL) previously reported so far. While their molecular profiles are studied elsewhere, data on primary intraparenchymal CNS cases remain limited.
