    Vascularized composite allotransplantation (VCA) restores function after severe injury but is limited by current diagnostic tools for rejection monitoring.

  • 2

    The Banff classification remains the gold standard for histopathological diagnosis of rejection but does not fully address antibody-mediated or chronic rejection.

  • 3

    Mucosal rejection may occur earlier or more severely than cutaneous rejection, highlighting the need for comprehensive assessment across different tissue types.

  • 4

    Emerging molecular assays, including donor-derived cell-free DNA and miRNA profiling, show promise for early and minimally invasive detection of rejection.

  • 5

    Standardization of diagnostic criteria and coordinated multicenter efforts are essential to improve early and accurate diagnosis in VCA.
