Extraskeletal myxoid chondrosarcoma is an unusual soft tissue sarcoma with distinctive histologic features. It once was called chordoid sarcoma because it resembles chordoma histologically. The lesion has been shown to be of chondroblastic origin. This lesion shown to have ultrastructural and molecular features distinct from that of myxoid chondrosarcoma of bone. We report a case of extraskeletal myxoid chondrosarcoma in forefoot.

Parachordoma is a very rare, slow-growing, and low-grade malignant tumor that occurs in the extremities and trunk. The differential diagnosis includes extraskeletal myxoid chondrosarcoma and chordoma in the histologic finding. Thus, histologic findings with immunohistochemistry may be helpful in distinguishing parachordoma from extraskeletal myxoid chondrosarcoma and chordoma. I report with a brief review of literatures one case of parachordoma of the chest wall which was successfully treated by en-bloc resection and chest wall reconstruction using 2 mm Gore-Tex$^{\circledR}$ soft tissue patch and free from recurrence for 16 months.

Intracranial extraskeletal myxoid chondrosarcoma is extremely rare, with only seven patients previously reported. We present a case report of a 21-year-old woman admitted for weakness in her right extremities and symptoms of increased intracranial pressure. Magnetic resonance imaging (MRI) revealed hydrocephalus and a well-enhanced large mass around her left thalamus. A left parietal craniotomy and a cortisectomy at the superior parietal lobule were performed. Total surgical resection was also performed, and pathology results confirmed an extraskeletal myxoid chondrosarcoma. Postoperative MRI showed no residual tumor, and the patient underwent radiotherapy. After six months of radiotherapy, the patient's headache and weakness had improved to grade IV. This malignant tumor showed high rates of recurrence in previous reports. We here report another occurrence of this highly malignant and rare tumor in a patient treated using total surgical excision and adjuvant radiotherapy.
