Due to this reason, BA has many similarities with GVHD seen after allogeneic hematopoietic-like lymphocytic infiltrate in portal space (Kupffer cells, CD4 T cells, and CD8 T cells), with predominance of CD24+ T helper (Th1) cells and a high number of cell adhesion molecules or human leukocyte antigen (HLA class II) markers (26). This evidence concerns the gene CD8A and breast angiosarcoma.
