A patient with angioimmunoblastic lymphadenopathy was treated with chemotherapy to complete remission for 13 years. A single relapse, self-limited, occurred followed 2 years later by the appearance of a disseminated non-Hodgkin's lymphoma with prominent cutaneous lesions and hypogammaglobulinemia. Cells from the peripheral blood and an affected lymph node were characterized by immunologic studies as deriving from the T8 subset of lymphocytes, suggesting a functional relationship between these suppressor cells and the patient's clinical manifestations.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is a distinct subtype of peripheral T-cell lymphoma (PTCL) and accounts for 2% of all non-Hodgkin lymphomas. Its typical characteristics include an aggressive course, progressive lymphadenopathy, hepatosplenomegaly, systemic symptoms, anemia, hypergammaglobulinemia, and generally poor prognosis.
Methods: We describe a rare case in which the left inguinal lymph node was completely excised and biopsied one year ago.

Angioimmunoblastic T-cell lymphoma (AITL) is a kind of aggressive T-cell lymphoma with significant enrichment of non-malignant tumor microenvironment (TME) cells. However, the complexity of TME in AITL progression is poorly understood. We performed single-cell RNA-Seq (scRNA-seq) and imaging mass cytometry (IMC) analysis to compare the cellular composition and spatial architecture between relapsed/refractory AITL (RR-AITL) and newly diagnosed AITL (ND-AITL).

Although rearrangement of the MYC oncogene (MYC-R) is frequently observed in aggressive B-cell lymphomas, it is extremely rare in T-cell malignancies. A 64-year-old man who had been under observation for several years because of asymptomatic pulmonary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALToma) was admitted to our hospital because of poor general condition and hypotension. Blood tests revealed thrombocytopenia and elevated serum lactate dehydrogenase levels, whereas computed tomography revealed systemic lymphadenopathy and splenomegaly.
