[Sarcomatoid carcinoma of the larynx].

Sarcomatoid carcinoma of the upper aerodigestive tract is an unusual neoplasm with differential cellular differentiation. Microscopically, sarcomatoid carcinomas have an element of squamous-cell carcinoma and a pleomorphic sarcoma-like component, which may simulate granulation tissue, malignant fibrous histiocytoma, osteosarcoma, or malignant giant-cell tumor of soft tissues.
