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.

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.

Association of both BCL2 positive and negative follicular lymphoma to clasical Hodgkin lymphoma and/or gray zone lymphoma.

We present a series of 9 follicular lymphomas that progressed/transformed into classical Hodgkin lymphoma (CHL). Three cases of CHL showed a syncytial pattern (SCHL) making the differential diagnosis to Gray zone lymphoma (GZL) challenging. None of these three cases presented in the mediastinum.

Leukaemic Presentation of Small-Cell Alk-Positive Anaplastic Large Cell Lymphoma in a Young Woman-Report of a Case with 9-Year Survival.

Anaplastic large cell lymphoma (ALCL) with leukaemic presentation (either ab initio or along the course of the disease) has been rarely reported. Irrespective of ALK expression in the neoplastic cells, it features a dismal prognosis. We report a rare case of leukaemic, small cell variant ALK-positive ALCL with 9-year survival in a young woman who was treated upfront with corticosteroids and standard chemotherapy, and review thoroughly the previously published cases.
