摘要

A 71-year-old man presented with cytopenias and splenomegaly. Diagnostic workup revealed T-cell large granular lymphocytic leukemia (T-LGLL), characterized by a clonal CD8+ T-cell population with STAT3 mutation. A rare morphological finding of myeloperoxidase-negative Auer rod-like inclusions in the leukemic lymphocytes was observed, a feature seldom reported in this T-cell malignancy.
