Dedifferentiated endometrial cancer: an atypical case diagnosed from cerebellar and adrenal metastasis: case presentation and review of literature.
Dedifferentiated endometrial cancer (DEC) is microscopically characterized by the presence of high-grade areas emerging from low-grade tumour. DEC is an aggressive tumour even when the dedifferentiated component represents only 20% of the entire neoplasm. A proper histological diagnosis is essential to define the most appropriate therapeutic approach for these tumors, since they are characterized by a particularly aggressive trend and by an extremely poor prognosis. We report a single case of DEC associated with dedifferentiated and adrenal metastasis, for which the patient underwent both abdominal-pelvic and cerebellar surgery. Dedifferentiated carcinoma of the endometrium is a poorly recognized neoplasm since they have not been clearly defined the histological features discriminating this neoplasm from high-grade endometrioid adenocarcinoma. Revising existing literature we found 79 described cases of central nervous system secondary involvement and 13 cases where the onset of the disease was characterized by neurological signs and symptoms. We could only find two reported cases of adrenal metastases originating from endometrial neoplasia but in no case of dedifferentiated endometrial carcinoma previously described has been reported the concomitant adrenal-cerebellar involvement.
