A 22-year-old male presented with proptosis of his right eye of one month's duration. No abnormalities were present regarding visual acuity, ocular motility, or fundus findings. Systemic examinations gave negative results. An orbital tumor, 25 mm in size, was detected by computed tomography and magnetic resonance imaging in the affected side. The tumor was located nasal-posterior to the eyeball and appeared to be in apposition with the orbital floor. The tumor was removed through a maxillary sinus approach. Histopathological studies led to the diagnosis of extraskeletal mesenchymal chondrosarcoma. To the best of our knowledge, this is only the fifth case reported in Japan of mesenchymal chondrosarcoma. Originating in the orbit.
一名22岁男性出现右眼突出，持续时间为1个月。视力、眼球运动或眼底检查均未发现异常。全身检查结果为阴性。通过计算机断层扫描和磁共振成像在患侧检测到一个25毫米大小的眼眶肿瘤。肿瘤位于眼球鼻后方，似乎与眶底相邻。通过上颌窦入路切除肿瘤。组织病理学研究诊断为骨外间叶性软骨肉瘤。据我们所知，这是日本报道的起源于眼眶的间叶性软骨肉瘤的第五例。
