Chondrosarcoma is one of the most frequent malignant primary tumors. Pelvic and proximal femur locations require extensive approaches with consequent difficulty soft tissue reconstruction. External hemipelvectomy usually procedure for these locations. It involves total en bloc resection lower extremity associated ipsilateral hemipelvis, resulting in a large coverage defect. In some cases, local...

Clear-cell chondrosarcoma is a rare, low-grade variant of chondrosarcoma characterized by slow growth, low metastatic potential, and a predilection for local recurrence long after treatment. We report an unusually aggressive case of clear-cell chondrosarcoma of the humerus with early metastasis to multiple bony sites including femur, thoracic and lumbar spine, sacrum, and iliac bone. Our purpos...

In spite of being the most common nonepithelial neoplasm, chondrosarcoma makes up only about 0.2% of all head and neck malignancies and approximately 1% of all laryngeal tumors. Primary laryngeal chondrosarcoma is rare with only 300 cases being reported in literature. Herein, we present a case of 61-year old male who presented with long-standing neck mass. Histopathological exami nation, reveal...

Secondary chondrosarcoma is a malignant chondroid tumor arising in a benign precursor. Synovial chondromatosis is a benign chondroid lesion that rarely transforms to chondrosarcoma. We present the case of a 54-year-old male with the diagnosis of low-grade secondary peripheral chondrosarcoma developed in the context of synovial chondromatosis. Cytogenetics revealed a novel aberration t(1;14)(q23...

UNLABELLED Primary sacral tumours are rare, therefore experience of managing their associated complications are very limited. Effective surgical treatment of pelvic chondrosarcoma remains a major challenge for orthopaedic surgeons, due to the complex anatomic structure of the pelvis, the lack of defined compartment borders, the close vicinity to vital structures, and the risk of jeopardizing pe...

The ability of chondrosarcoma cell-derived preparations to stimulate an increase in the motility of bovine capillary endothelial (BCE) cells was quantitated using a phagokinetic track assay which measures the area of tracks produced by BCE cells after ingestion of gold particles. Chondrosarcoma preparations stimulated a 2-fold increase in the mean track area produced by BCE cells in an 18-hr in...

Chondrosarcoma is considered as a common primary bone sarcoma. These sarcomas can form large masses without any specific symptoms because there are no barriers in pelvic anatomy to prevent the enlargement of tumors, and can mimic ovarian masses. We present a pelvic chondrosarcoma in a woman aged 37 years who was misdiagnosed as having an ovarian mass due to the limited information obtained from...

Mammary sarcomas are uncommon tumors. When tumors like malignant cystosarcomaphyllodes and metaplastic carcinoma, where malignant cartilaginous areas may be present, are excluded, only nine cases have been reported to date.We report another case of primary chondrosarcoma of the breast here. A 24-year-old Mediterranean woman presented with a painful mass in the right breast and a physical examin...

Primary extraskeletal myxoid chondrosarcoma of the pulmonary arteries is a very rare entity. Multimodality imaging reports on this entity are few. Myxoid chondrosarcoma is characterized by chondroid and neurogenic differentiation in extraskeletal locations. These tumours represent fewer than 2.5% of all soft-tissue sarcomas, and are most commonly found in the lower extremities, limb girdles, di...

A 45-year-old female presented with complaint of a lump in the right breast for the last 6 months. Excisional biopsy had been performed outside our institution, which was suggestive of a pure mammary chondrosarcoma. Modified radical mastectomy of the right breast was performed and histopathology was suggestive of a pure mammary chondrosarcoma of the right breast. One axillary lymph node was pos...
