title: [Sarcomatous carcinoma versus malignant fibrohistiocytoma. Differential diagnosis of a case of cervical presentation].
abstract: A case is presented of cervical sarcomatoid carcinoma that was initially confused with malignant fibrohistiocytoma. The similarity in their histological features and compatible immunohistochemical tests make it necessary to include sarcomatoid carcinoma in the differential diagnosis malignant fibrohistiocytoma. Many atypical presentations of malignant fibrohistiocytoma may be true sarcomatoid carcinomas. Our case is special because the patient had a recent spinocellular carcinoma of the lip, in which the undifferentiated portion had originated lymph node metastasis.
