Miscellaneous primary tumors and metastatic tumors of the uterine cervix.

Apart from squamous cell carcinomas and adenocarcinomas (and their precursors), a variety of less common neoplasms, both benign and malignant, arise or initially present within the uterine cervix. This review considers the clinical and pathological features and differential diagnosis of these tumors, which include cervical small cell (neuroendocrine) carcinomas, sarcomas and mixed mullerian tumors, lymphomas and leukemias, germ cell tumors, malignant melanomas, trophoblastic tumors, and metastatic carcinomas. Benign tumors of the cervix are also briefly discussed.
