However, the clinical characteristics and prognosis of Bcc infections in patients with hematological malignancies remain unreported. This study aimed to delineate the clinical trajectory from colonization to active infection and to identify prognostic factors influencing outcomes in hematologic malignancy patients with Bcc colonization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective analysis of 185 hematological malignancy patients with Bcc colonization at the Department of Hematology, The First Affiliated Hospital of Soochow University, from November 2019 to November 2022.
