The authors present a rare case of intradural extramedullary spinal chondrosarcoma. This 38-year-old man presented with urinary retention and lower-limb weakness. Magnetic resonance imaging demonstrated a thoracic intradural extramedullary spinal tumor, which was resected. Histopathology revealed a meningeal myxoid chondrosarcoma. Despite adjuvant radiotherapy, the patient had multiple recurrences and metastases and died 18 months following his first surgery. The management of the rare entity of spinal canal chondrosarcoma is discussed.

Aggressive Subtypes of Laryngeal Chondrosarcoma and their Clinical Behavior: A Systematic Review.
Oncol Ther

Coordinator of the International Head and Neck Scientific Group, Padua, Italy.
Introduction: Laryngeal chondrosarcoma (CS) is a rare indolent malignant tumor. High-grade (G3), dedifferentiated (DD), and myxoid (MY) CSs are considered more aggressive subtypes due to their metastatic potential and relatively poor outcomes. The aim of this systematic review is to evaluate treatment modalities and survival outcomes in patients affected by these rarer CS subtypes.

Sarcoma classification includes atypical lipomatous tumor/well-differentiated liposarcoma (WDL) and dedifferentiated liposarcoma (DDL), myxoid liposarcoma, and pleomorphic liposarcoma. DDL is most prevalent in the retroperitoneum and often has two distinct components, a well-differentiated lipomatous component and a dedifferentiated nonlipomatous component that could be morphologically similar to malignant fibrous histiocytoma (MFH) or fibrosarcoma.

Introduction: Percutaneous cryoablation is a first-line therapeutic option for primary neoplasms and metastatic lesions of the musculoskeletal system. Treatment of abdominal wall tumors is challenging as surgical resection can be highly morbid and necessitate complex reconstructive surgery; the efficacy of cryoablation for abdominal wall tumors may be limited by inadequate posterior margins owing to the proximity of intra-abdominal organs. With laparoscopy and insufflation, peritoneal structures can be safely mobilized away from the abdominal wall, allowing for adequate deep margin freeze and visualization of the ice ball.
