Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL). AITL typically presents with lymphadenopathy, fever, rash, hepatosplenomegaly, and rarely polyarthritis. We report the case of a 50-year-old female who presented with lymphadenopathy, rash, and symmetric polyarthritis. She was later diagnosed with AITL and was treated with chemotherapy with resolution of arthritis. AITL should be suspected in paitents presenting with rheumatoid-like arthritis and diffuse lymphadenopathy.

Hodgkin Reed-Sternberg (HRS) cells of classic Hodgkin lymphoma (cHL), like many solid tumors, elicit ineffective immune responses. However, patients with cHL are highly responsive to PD-1 blockade, which largely depends on HRS cell-specific retention of MHC class II and implicates CD4 T cells and additional MHC class I-independent immune effectors. Here, we utilize single-cell RNA sequencing and spatial analysis to define shared circulating and microenvironmental features of the immune response to PD-1 blockade in cHL.

Children with T-ALL/LBL require prompt diagnosis and treatment. Flow cytometric analysis of T-lineage and immaturity markers usually leads to a straightforward diagnosis. However, rare cases of T-ALL expressing bright CD45 and lacking expression of immature markers can be a diagnostic conundrum and difficult to differentiate from mature T-cell lymphomas lacking surface CD3 expression or aberrantly expressing immature markers, which affects treatment decisions and prognosis.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL), representing the majority of all lymphomas arising in the skin. The disease treatment focuses on managing symptoms and preventing disease evolution. To date, there is no gold standard for MF-CTCL treatment.

Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), a scaffold protein, plays a pivotal role in the NF-κB pathway downstream of T-cell receptors (TCRs) and B-cell receptors (BCRs). As a key signaling hub, MALT1 integrates various pathways, making it essential for both innate and adaptive immunity. However, its role in the antibacterial immune responses of crustaceans remains unclear.
