Halo naevi and café au lait macule regression in a renal transplant patient on immunosuppression

A case of halo naevi and café au lait macule regression in a renal transplant patient receiving long‐term immunosuppressive therapy is described. We propose the direct transfer of an auto‐reactive antibody, CD 8 T ‐cells or tumour necrosis factor α from the transplant donor to the recipient as a possible cause. We have also considered insufficient immunosuppressive therapy as a possible mechanism.
