Re resection was performed (third operation altogether).
Tumour sections show nodular fragments of a moderately cellular chondroid neoplasm. Tumour cells are set within a variably loose myxoid to dense cartilaginous stroma. Frequent binucleated tumour cells are present. Scattered mitotic figures are identified. Tumour cells contain enlarged, hypochromatic, angulated nuclei.
Immunohistochemistry results show tumour cells stain: S100+, M2A+, CAM5.2- and Ki67 40-50%.
