Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic malignancy [1, 2]. Currently, no standard treatment has been established for this disease. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only potentially curative option [3, 4], while patients ineligible for allo-HSCT or relapse after transplantation had poor prognosis.

Abstract Aims Tissue eosinophilia is commonly observed in T-cell and classic Hodgkin lymphomas, but rarely in B-cell lymphomas. Herein, we present the first report of a case series on nodal marginal zone lymphoma (NMZL) with tissue eosinophilia. Methods and results All 11 patients in this study had nodal disease at primary presentation. The mean age at diagnosis was 64 years. The mean follow-up period was 39 months, and all patients were alive.
