Fig 3. Representative CT-scan images and immunohistochemistry results using anti-CD20 and anti-CD103 antibodies in a PR patient.

(A, a) Para-aortic lymph node metastasis recurrence was found (yellow circle). (b) Six months later, the metastatic lymph node decreased. (B, a) Aggregates of CD20⁺ cells were observed in the tumor tissue, which were considered TLS. Scale bar: 500 μm. (b) CD103⁺ T cells were found around TLS (black arrowhead). Scale bar: 500 μm.
