Background: Defined as rare large azurophilic cytoplasmic inclusions, Pseudo-Chediak-Higashi granules mimic those in granulocytes cytoplasm of Chediak-Higashi syndrome. Rare cases of hematopoietic and lymphoid tissues tumors showed Pseudo-Chediak-Higashi inclusions in cytoplasm, some of which presented with unusual morphological characteristics.
Methods: Herein, we report the first case, in which rare pseudo-Chediak-Higashi inclusions were observed in therapy-related acute myeloid leukemia with myelodysplasia-related changes (t-AML-MRC).
Results: The rare pseudo-Chediak-Higashi inclusions may be positive for Sudan black, and some scholars think that these rare inclusions are a kind of dysgranulopoiesis.
Conclusions: The case highlights the significance of an integrated diagnostic work-up, with an interesting effect for morphology.

Pseudo-Chediak-Higashi granules are large cytoplasmic inclusions commonly encountered in myeloblasts or other myeloid precursors in acute myeloid leukemia and myelodysplastic syndromes. However, pseudo-Chediak-Higashi granules are rarely found in acute lymphoblastic leukemia (ALL). We present the case of an 8-year-old boy who was diagnosed with ALL with pseudo-Chediak-Higashi granules in the initial diagnosis and relapse, acting like a characteristic marker.
