Abstract:
We report an unusual case of uterine corpus metastasis from rectal adenocarcinoma detected using F-FDG PET/CT. A 47-year-old woman was diagnosed with rectal adenocarcinoma and treated with surgery and radiochemotherapy 3 years ago. During follow-up, she presented with lower abdomen pain and elevated tumor markers, but ultrasonography findings were unremarkable. We performed an F-FDG PET/CT scan, which showed intense F-FDG avidity in the myometrium of the uterine corpus. Uterine corpus metastasis was suspected, and complementary MRI and diagnostic curettage histopathology confirmed uterine metastasis from rectal adenocarcinoma.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
