Spinal Enchondromas in the Cervical Spine: Rarity, Recurrence and the Importance of Long-Term Surveillance.

Introduction: Chondromas are benign cartilaginous tumors classified into periosteal chondromas and enchondromas. While periosteal chondromas grow on the bone surface, enchondromas develop within the medullary cavity. Enchondromas constitute 4-8% of all bone tumors, with spinal enchondromas being exceptionally rare, particularly in the cervical region.

Management of Cervical Spine Metastasis from Renal Cell Carcinoma: A Rare Case Report with an Overview.

Introduction: Renal cell carcinoma (RCC) accounts for 2-3% of adult malignant tumors, often metastasizing to bones, especially the spine. Spinal metastasis has a poor prognosis, but solitary spinal tumors have better outcomes with targeted chemotherapy, radiotherapy, and newer surgical approaches. Due to RCC's high vascularity and resistance to treatments, en bloc vertebrectomy with anterior and posterior fixation is the gold standard for solitary lesions.
