Diffuse CD30‐Positive Cutaneous Infiltrate in a Clinically Suspected Hidradenitis Suppurativa Lesion: Histopathologic and Diagnostic Challenges

Journal of Cutaneous Pathology, Volume 53, Issue 9, Page 809-814, September 2026.
ABSTRACT Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder affecting apocrine gland–bearing areas. We report a 38‐year‐old male with a lesion in the left axilla, initially clinically interpreted as HS and resistant to antibiotics.

BCR and TLR signaling pathways are recurrently targeted by genetic changes in splenic marginal zone lymphomas

Haematologica, 2012
The genetics and pathogenesis of splenic marginal zone lymphoma are poorly understood. The lymphoma lacks chromosome translocation, and approximately 30% of cases are featured by 7q deletion, but the gene targeted by the deletion is unknown.

NLRC5‐Deficient Macrophages Promote a Tumor‐Permissive Phenotype via AXL‐ and MERTK‐Mediated Efferocytosis

The FASEB Journal, Volume 40, Issue 15, 15 August 2026.
Defective NLRC5 signaling in macrophages drives TAM phenotype and anti‐inflammatory responses via STAT3/ERK, leading to tumor‐permissive conditions and gastric lymphoid neogenesis during Helicobacter infection. ABSTRACT The innate immune protein NLRC5 plays a key role in cancer immune surveillance.

Decoding IGLL5 Mutation‐Mediated BCR Signaling: A Novel Mechanism of CD8+ T Cell Exhaustion and Ocular MALT Lymphoma Progression

Advanced Science, Volume 13, Issue 44, 7 August 2026.
OAML harbors recurrent IGLL5 mutations that reinforce CD79A/CD79B‐associated BCR signaling. Mechanistic analysis of the S47G and A54G variants reveals induction of CXCL10/CXCL11, enhanced CD8+ T‐cell recruitment, and exhaustion‐associated dysfunction, supporting an immune‐tolerant niche.

Regression of Advanced Gastric MALT Lymphoma after the Eradication of Helicobacter pylori

Gut and Liver, 2012
Background/AimsHydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) and peroxisome proliferator-activated receptor gamma (PPARγ) ligands can modulate cellular differentiation, proliferation, and apoptosis through various pathways.

Survival Outcomes and Prognostic Factors in Patients With Primary Central Nervous System Low‐Grade B‐Cell Lymphoma: A Population‐Based Cohort Study

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT The incidence of primary central nervous system low‐grade B‐cell lymphoma (PCNSL‐LG) is rare. We aimed to provide the first large‐scale analysis of treatment modalities, survival trends, and prognostic factors for PCNSL‐LG. Patient data diagnosed between 2000 and 2021 were extracted from the Surveillance, Epidemiology, and End Results (SEER ...

Targeting Spatiotemporal Heterogeneity of oncomiRNAs: A New Frontier in Cancer Therapy

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background miRNAs are short RNA transcripts that modulate gene expression after transcription and have emerged as pivotal regulators of cancer biology. A subset, termed oncomiRNAs, functions as oncogenes or tumor suppressors, influencing key cellular events such as cell growth, programmed cell death, neovascularization, tissue invasion, and ...

Maltoma of Thyroid: A Rare Thyroid Tumour

Case Reports in Otolaryngology, 2013
Introduction. Primary thyroid lymphomas constitute up to 5% of all thyroid malignancies and can be divided into non-Hodgkin’s lymphomas (NHLs) of B- and T-cell types, as well as Hodgkin’s lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphomas are

Temperature Safeguards and Peri‐Procedural Strategies for Stem Cell Collection in Cold Agglutinin Disease: A Case Report and Literature Review

Journal of Clinical Apheresis, Volume 41, Issue 4, August 2026.
ABSTRACT Cold agglutinins can result in red blood cell (RBC) agglutination and lysis at low temperatures. Temperature sensitivity during stem cell mobilization, processing, and infusion poses unique procedural challenges in patients with active cold agglutinins.
