Chondrosarcoma is a malignant cartilage-forming tumor that affects predominently the middle-aged population. There are three histologic grades, but differentiation of Grade I tumors from enchondromas can be difficult. The measurement of polypoidy (augmented chromosomal content per cell) appears to offer a method of segregation of benign from low-grade ...

Osteosarcoma, Chondrosarcoma, and Chordoma.
Journal of Clinical Oncology, 2018Osteosarcoma (OS), chondrosarcoma, and chordoma are characterized by multiple challenges to the investigator, clinician, and patient. One consequence of their rarity among sarcomas, as well as their biologic and clinical heterogeneity, is that management

Dedifferentiated chondrosarcoma.
The Journal of Bone & Joint Surgery, 1988The cases of forty-six patients who had dedifferentiated chondrosarcoma were reviewed. Two groups were identified: one in which a low-grade malignant chondrosarcoma was the precursor lesion and one in which a moderate to high-grade malignant chondrosarcoma was the precursor lesion.

Dedifferentiated chondrosarcoma: An aggressive variant of chondrosarcoma
Asian Cardiovascular and Thoracic Annals, 2014Dedifferentiated chondrosarcomas are a rare and aggressive subtype of chondrosarcoma with a bimorphic pattern on histopathology. Rib is a rare site of dedifferentiated chondrosarcoma. Diagnosis of this subtype preoperatively can be challenging. Treatment options for dedifferentiated chondrosarcoma are limited because they are chemoresistant, and ...

Journal of Cancer Research and Clinical Oncology, 1996
This study was undertaken to analyse metastases of patients with intermediate- or high-grade chondrosarcomas. Out of 24 intermediate-grade tumours, 5 (21%) developed metastases, as did 6 of 10 high-grade tumors (60%) (P = 0.04). Four patients developed pulmonary metastasis only, 5 developed both pulmonary metastasis and metastases of the other sites ...

The Journal of Laryngology & Otology, 1995
AbstractA case of a low grade chondrosarcoma of the cricoid cartilage which had been diagnosed intially as a chondroma is presented. The tumour reurred twice after limited surgical resections. Total laryngectomy was inecvitable due to near total involvement of the cricoid cartilage and subsequent histological examination revealed a low grade ...

Dedifferentiated chondrosarcoma (DDCHS) is an aggressive type of chondrosarcoma that results from high‐grade transformation of a low‐grade chondrosarcoma. Mutations in the isocitrate dehydrogenase (IDH) 1 gene and the IDH2 gene that lead to increased d‐2‐

Enchondroma and Chondrosarcoma
Seminars in Musculoskeletal Radiology, 2000Enchondroma and chondrosarcoma are two of the most commonly encountered primary bone lesions in the typical radiology practice. The purpose of this article is to review the clinical, radiological, and pathological features that distinguish conventional chondrosarcoma from enchondroma.

A case of chondrosarcoma of the hand recurred 4 times over a period of 32 years. Forty-seven cases of hand chondrosarcomas have been found in the literature. Histological diagnosis is difficult in differentiating chondrosarcomas from benign chondromas. Pain and swelling are the main symptoms of recurrence.
