Pharynx chordoma

Chordoma is derived from the residual of the chordoma of the embryo. The degenerated chordae are usually embedded in the sphenoid bone and the occipital bone, but some can be folded into the pharyngeal wall to the ventral side. The cells at the fusion with the pharyngeal epithelium have the potential for rapid growth. It can form chordoma, which is a rare low-grade malignant tumor. The pathology showed that the tumor was composed of typical vacuole cells and a mucus matrix, which was characterized by a leaf-separated structure. The cells grew in irregular strands, clumps, or pseudoacinoids, and could form large vacuole syncytia cells. Can occur at any age, mostly middle-aged, more men than women.
