Mesenchymal chondrosarcoma of the orbit: A case report with 5?years of follow-up

摘要

Mesenchymal chondrosarcoma is a rare orbital tumor. Several case reports of this rare tumor have been published in the literature but only 6 cases have documented a follow up of 5?years or more. We report a case of 28?year-old female who presented with left orbital mass. Computed Tomography (CT) revealed a lobulated mass in the superior extraconal space with dense intralesional calcification. Patient underwent complete resection of the mass and histopathology was suggestive of mesenchymal chondrosarcoma. He was given adjuvant radiotherapy and there was no recurrence or metastasis at 5?years of follow-up. The case highlights that a complete resection with adjuvant radiotherapy in cases of orbital mesenchymal chondrosarcoma offers excellent prognosis.
