In this patient, immunohistochemistry, as well as consultation with the pathologist at the university hospital, showed that the adenosarcoma originated in the uterine cavity, the adenosarcoma in the cervical canal was due to a downward invasion of the uterine lesion, the lesion was low grade, and no sarcoma overgrowth was seen as demonstrated in the pathology report (p53-negative, low positivity for Ki-67, etc.). This evidence concerns the gene TP53 and sarcoma.
