Histopathological changes in experimental free thyroid transplants

Free thyroid autotransplants into new receptor sites have been tried in 28 dogs, by two different techniques. Good but irregular histopathological survival of thyroid acini has been found after free autotransplantation of bisected and everted thyroid lobes into the external genitalia of dogs. The results have been very encouraging and the functional assessment of these implants is essential; such work is already in progress in our laboratory. Our findings and their significance have been discussed.
