Chronic myeloid leukemia (CML) is a hematologic malignancy characterized by an uncontrolled proliferation of myeloid cells, particularly neutrophils. It is revealed through the detection of a Philadelphia chromosome (BCR;ABL).

While tyrosine kinase inhibitors have dramatically improved short and middle-term outcomes, in some resistant or relapsing cases, allogeneic hematopoietic stem cell transplantation (HSCT) can be a curative option.

In this first-ever documented case, we report the successful use of fecal microbiota transplantation (FMT) to treat both corticosteroid-resistant gastrointestinal GvHD and concomitant cryptosporidiosis, leading to significant clinical improvement in a patient post umbilical cord blood HSCT.
