Primary Tracheal Rosai‐Dorfman Disease Coexisting With Active Pulmonary Tuberculosis

Respirology Case Reports, Volume 14, Issue 8, August 2026.
We report a rare case of primary tracheal Rosai‐Dorfman disease (RDD) with active pulmonary tuberculosis. Bronchoscopic resection immediately relieved > 90% airway obstruction, and anti‐tuberculosis therapy was given, resulting in no recurrence at one‐year follow‐up. ABSTRACT Rosai‐Dorfman disease (RDD) rarely involves the trachea, and active pulmonary

A Rare Case of Cutaneous Crystal‐Storing Histiocytosis With Kappa Light Chain Restriction and Unusual BCL6 Expression

Journal of Cutaneous Pathology, Volume 53, Issue 8, Page 682-686, August 2026.
ABSTRACT Crystal‐storing histiocytosis (CSH) is a rare histopathologic phenomenon characterized by the accumulation of crystalline material within histiocytes, most often associated with lymphoplasmacytic or plasma cell neoplasms. Cutaneous involvement is uncommon and may present diagnostic challenges.

Low Risk of Central Nervous System Relapse Among Patients With T‐Cell/Histiocyte‐Rich Large B‐Cell Lymphoma Despite High‐Risk Disease Presentation

European Journal of Haematology, Volume 117, Issue 2, Page 358-365, August 2026.
ABSTRACT T‐cell/histiocyte‐rich large B‐cell lymphoma (THRLBCL) is a rare subtype of large B‐cell lymphoma (LBCL) for which central nervous system (CNS) relapse remains a devastating complication. The CNS International Prognostic Index (IPI) is usually used to predict the risk of CNS relapse. However, the overall risk of CNS relapse among patients with
