Figure 5 Histologic appearance of tumor, displaying sheets of neoplastic myxoid and hyalin cartilage, surrounded by fibrous connective tissue; the cells are pleomorphic and disorganized, with multiple and pyknotic nuclei and atypical mitotic figures. A, Lesion abutting normal discal tissue (100× magnification). B, Islands of tumor within adjacent normal periarticular tissues (40× magnification). Histologic stains are hematoxylin and eosin.

Figure 8 Radiographic status of calcifications (arrows) in later years. A, A 2006 film shows calcifications that were interpreted as being with the lateral pterygoid muscle and stable since 2003. B, A 2009 film shows calcifications that were reported as stable without evidence of soft tissue mass. C, Scan from 2013 was interpreted as showing essentially no change during the previous 10 years.
