Polypoid carcinoma of the uterine cervix simulating "pseudosarcoma" and "carcinosarcoma" of esophagus and upper respiratory tract.

The patient presented with a polypoid mass, arising from the uterine cervix. Histologically the mass appeared to have two components, both of which were malignant. The first component was a surface squamous cell carcinoma, while the second was an infiltrating pseudosarcomatous lesion. The polypoid tumor mimics lesions which arise in the esophagus, pharynx, larynx, and mouth, and which have been variously classified as pseudosarcoma or carcinosarcoma. Treatment consisted of applications of radium followed, in 5 months, by radical abdominal hysterectomy and pelvic lymphadenectomy. The patient remains free of any clinical recurrence of the tumor after more than 2 years, suggesting a favorable prognosis. Similar lesions occurring elsewhere in the body also have a low propensity for metastases.
