Cervical carcinosarcomas are rare neoplasms that aggressively progress and belong to the histological group of mixed tumors with both epithelial and mesenchymal components (malignant mixed Müllerian tumors). At diagnosis, most patients present with vaginal bleeding and a palpable cervical mass. Given the rarity of this neoplasm, there is no consensus regarding the management of these patients and should be approached on a case-by-case basis, taking into consideration the clinical and pathological features of the tumor. The authors describe a woman with mesonephric cervical carcinosarcoma and review the literature regarding these rare tumors to better understand the natural history of these neoplasms.
