Intracranial Mesenchymal Chondrosarcoma is a very rare and uncommon entity that affects young adults. We came across one such patient who presented with severe headache and intermittent nausea and vomiting. The clinical, radiological preoperative diagnosis was a meningioma, on histological examination it turned out to be mesenchymal chondrosarcoma of tentorial region in posterior fossa, uncommo...

A 52 year old man developed an extraskeletal mesenchymal chondrosarcoma (ESMC) arising from the pleura. Clinically, the tumour mimicked a mesothelioma. Fine needle biopsy was consistent with the diagnosis of sarcomatoid mesothelioma. Histological examination of multiple tumour samples, supported by immunohistochemical characterization, made it possible to correctly diagnose extraskeletal mesenc...

UNLABELLED Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric imp...

Extraskeletal mesenchymal chondrosarcomas (EMCs) are relatively uncommon, and a location in the upper extremity, especially in the shoulder or axillary region, is rare. Furthermore, the radiographic findings of EMCs do not show any features that distinguish them from other neoplasms, and therefore, definitive diagnoses are made based on histological features. EMC is an aggressive tumor with a p...

Chondrosarcoma is an uncommon malignant neoplasm of cartilaginous origin. Extraskeletal chondrosarcomas are far less common than their intraosseous counterparts, representing approximately 2% of all soft tissue sarcomas. Clinically, extraskeletal mesenchymal chondrosarcoma (EMC) shows a very fast progression. It also has a high incidence of local recurrence and distant metastasis. The most comm...

Clear cell chondrosarcoma may be difficult to distinguish from metastatic clear cell renal carcinoma. Clear cell chondrosarcoma is strongly positive for 5100 and negative for epithelial markers. Clear cell carcinoma is cytokeratin positive and may also be positive with SiQO. S100 may also be useful in confirming grade 3 chondrosarcoma and mesenchymal chondrosarcoma. SiQO may assist in distingui...

Extraskeletal mesenchymal chondrosarcoma is rare and metastasis to the pancreas is extremely rare, with only four cases reported in the literature. The therapeutic effectiveness of chemotherapy remains uncertain. We report a 39-year-old man with extraskeletal mesenchymal chondrosarcoma of the buttock, who had metastases to the pancreas, bones, and lung. He underwent distal pancreatectomy, resec...

The iliac vein is an extremely rare site for mesenchymal chondrosarcoma, and patients with primary extraskeletal mesenchymal chondrosarcoma arising from a vein always suffer a very poor prognosis. We report a case of a 45-year-old female who presented with a 5-month history of left leg edema in 2015. Contrast-enhanced computed tomography showed a large mass in the left iliac vein with scattered...

Mesenchymal chondrosarcomas are extremely rare and aggressive tumors that primarily affect patients between the ages of 20 30. These neoplasms typically found in lower limbs cranial region. Their occurrence within soft tissues is exceedingly rare, initial presentation often includes immediate metastatic dissemination. Given extraordinarily low prevalence extraskeletal mesenchymal chondrosarcoma...
