This is the first report of a fibrocartilaginous mesenchymoma in the spine.
This is a rare bone tumor composed of islands of hyaline cartilage in a collagen-producing spindle cell stroma. Seven cases of fibrocartilaginous mesenchymoma have been reported previously. Of these, four occurred in the long bones.
The tumor is hypercellular with mild nuclear hyperchromasia. Few mitotic figures are present. However, it is highly infiltrative, and in the present patient, it completely encircled the spinal cord. Vertebrectomy was required to ensure tumor eradication.
Five years after tumor resection, femoral head allograft replacement of the vertebral body, and posterior spinal stabilization, there was no evidence of tumor recurrence.
这是关于脊柱纤维软骨间叶瘤的首例报告。
这是一种罕见的骨肿瘤，由产生胶原的梭形细胞基质中的透明软骨岛组成。此前已报告过7例纤维软骨间叶瘤。其中，4例发生于长骨。
肿瘤细胞丰富，核轻度深染。有少量核分裂象。然而，它具有高度浸润性，在本病例中，它完全包绕了脊髓。需要进行椎体切除术以确保肿瘤根除。
肿瘤切除、椎体同种异体股骨头置换及后路脊柱稳定术后5年，无肿瘤复发迹象。
