Primary mesenchymal chondrosarcoma of the orbit: Histopathological report of 3 pediatric cases

We describe 3 additional pediatric cases with primary orbital MCS and they were all males. Our cases presented with proptosis and calcific orbital masses on imaging studies. Histopathological examination of the excised masses shared the typical presence of undifferentiated mesenchymal cells and immature areas of cartilage. The diagnosis of MCS was further confirmed by immunohistochemical staining. Brief review of the literature in relation to this diagnosis in the orbit is also presented.
