PURPOSE: Mesenchymal chondrosarcoma (MCS) is an aggressive variant of chondrosarcoma and is a rare tumor, particularly within the pediatric population. Commonly, MCS originates in the bone, but it can also arise in extraskeletal sites, such as the brain and the intraspinal area. Due to the rarity of this tumor, there are no guidelines for its optimal treatment. METHODS: We report a case of intradural extramedullary MCS, located at the T11-T12 level, in a 14-year-old male...

OBJECTIVES: There was no consensus regarding the treatment of intracranial chondrosarcoma (CSA). The study aimed to evaluate the adverse factors for progression-free survival (PFS) and overall survival (OS) and to propose a treatment strategy for CSA. METHODS: The clinical chart and radiographic data of 106 consecutive cases (mesenchymal and conventional CSA in 18 and 88 patients, respectively) of surgically treated CSAs were retrospectively reviewed. RESULTS: Gross total resection was achieved in 43 patients (40...

An indoor-only, 5-year-old, spayed female domestic shorthair cat presented for an ophthalmic examination of the left eye. An intraocular tumor with secondary glaucoma and blindness was diagnosed; the globe was enucleated and sent for histopathological examination. Gross examination revealed a solid white mass filling the entire vitreous space and replacing the iris and ciliary body. The lens and retina appeared to be similarly replaced by the neoplasm. Histological examination revealed a complete loss of the internal ocular structures, with a ruptured capsule as the only remnant of the lens within an extensive malignant mesenchymal neoplastic cell proliferation...

BACKGROUND: Prosthetic reconstruction may be a promising treatment for peri-acetabular malignant bone tumour; however, it is associated with a high complication rate. Therefore, prosthetic design and approach of prosthetic reconstruction after tumour resection warrant study. METHODS: We retrospectively analyzed 11 patients with peri-acetabular malignant bone tumours treated by personalized 3D-printed hemipelvic prostheses after en bloc resection between 2015 and 2016...

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 calcifications. Wide-margin resection was performed, and histopathologic and immunohistochemical analyses confirmed the presence of intraluminal mesenchymal chondrosarcoma with local invasion out of the vein wall...

Bone sarcomas are rare, highly malignant mesenchymal tumours that affect teenagers and young adults, as well as older patients. Despite intensive, multimodal therapy, patients with bone sarcomas have poor 5-year survival, close to 50%, with lack of improvement over recent decades. TNF-related apoptosis-inducing ligand (TRAIL), a member of the tumour necrosis factor (TNF) ligand superfamily (TNFLSF), has been found to induce apoptosis in cancer cells while sparing nontransformed cells, and may therefore offer a promising new approach to treatment...

BACKGROUND: Extraskeletal mesenchymal chondrosarcoma (ESMCS) is an unusual pathologic variant of chondrosarcoma. There are no specific clinicoradiographic parameters to distinguish it from other intracranial pathologies. The diagnosis can be established only on the basis of histopathology, which may pose significant challenges in certain unusual locations. PURPOSE: In this case, we discuss the pitfalls in diagnosis, management, and major characteristics of ESMCS with a review of current literature...

The cell-based therapies could be potential methods to treat damaged cartilage tissues. Instead of native hyaline cartilage, the current therapies generate mainly weaker fibrocartilage-type of repair tissue. A correct microenvironment influences the cellular phenotype, and together with external factors it can be used, e.g., to aid the differentiation of mesenchymal stem cells to defined types of differentiated adult cells. In this study, we investigated the effect of long-term exposure to 5% low oxygen atmosphere on human chondrosarcoma HCS-2/8 cells...

Chondrosarcoma is the most common bone sarcoma in adults. Conventional chondrosarcoma, the commonest histological subtype, is largely resistant to anthracycline-based chemotherapy. There have been anecdotal reports of durable clinical benefit with antiangiogenic agents in this disease. A retrospective search of patients treated at three sarcoma referral centers was performed to identify patients with advanced chondrosarcoma treated with antiangiogenic agents. The aim of this study was to evaluate the efficacy and safety of antiangiogenic agents in advanced chondrosarcoma...

OBJECTIVE: Programmed death ligand 1 (PD-L1) found on tumor cells has recently been reported to have a key role in the development and dissemination of many tumors, such as lung and breast carcinomas. In this study, we retrospectively analyzed PD-L1 expression among different types of sarcomas. MATERIAL AND METHOD: Tissue microarrays of 3-4 mm diameter were composed from paraffin blocks of 222 various sarcomas. Slides prepared from microarrays were stained for PD-L1 antibody (Cell Signaling, E1L3N®) using Leica Bond Autostainer...

Mesenchymal chondrosarcoma is a rare orbital tumor. Several case reports of this rare tumor have been published in the literature but only 6 cases have documented a follow up of 5 years or more. We report a case of 28 year-old female who presented with left orbital mass. Computed Tomography (CT) revealed a lobulated mass in the superior extraconal space with dense intralesional calcification. Patient underwent complete resection of the mass and histopathology was suggestive of mesenchymal chondrosarcoma. He was given adjuvant radiotherapy and there was no recurrence or metastasis at 5 years of follow-up...

Cartilage-forming tumors of bone are a heterogeneous group of tumors with different molecular mechanisms involved. Enchondromas are benign hyaline cartilage-forming tumors of medullary bone caused by mutations in IDH1 or IDH2. Osteochondromas are benign cartilage-capped bony projections at the surface of bone. IDH mutations are also found in dedifferentiated and periosteal chondrosarcoma. A recurrent HEY1-NCOA2 fusion characterizes mesenchymal chondrosarcoma. Molecular changes are increasingly used to improve diagnostic accuracy in chondrosarcomas...

Soft-tissue sarcomas(STSs)are rare mesenchymal tumors, accounting for less than 1%of all adult malignancies. STSs also have diversity, with more than 50 different histological subtypes. While surgical complete resection is a definitive treatment for localized STS, chemotherapy is the treatment option for managing locally advanced and metastatic STS. Although doxorubicin ±ifosfamide is still the first-line therapy for most STS subtypes, some STSs(alveolar soft part sarcoma, clear cell sarcoma, epithelioid sarcoma and extraskeletal myxoid chondrosarcoma)have been reported to have little response to these cytotoxic chemotherapies...

AIMS: Neuroblastoma shows considerable histological overlap with other small round blue cell tumours. PHOX2B, a transcription factor that is essential for autonomic nervous system development, has been reported as an immunohistochemical marker for neuroblastoma. The aim of this study was to validate the specificity and diagnostic utility of PHOX2B for peripheral neuroblastic tumours. METHODS AND RESULTS: We evaluated 240 cases (133 in whole-tissue sections; 107 in tissue microarrays), including 76 peripheral neuroblastic tumours (median age 2 years; including four adults) and 164 other tumours: 44 Wilms tumours; 20 Ewing sarcomas; 10 each of CIC-rearranged round cell sarcomas, poorly differentiated synovial sarcomas, lymphoblastic lymphomas, alveolar rhabdomyosarcomas, embryonal rhabdomyosarcomas, mesenchymal chondrosarcomas, Merkel cell carcinomas, olfactory neuroblastomas, and melanomas; and five each of NUT midline carcinomas and desmoplastic small round cell tumours...

Mesenchymal chondrosarcoma (MC) is a rare malignant neoplasm bearing characteristic dimorphic pattern histologically. We describe two rare cases of primary MC involving two different visceral organs (1) a 24-year-old man with solid renal mass and, (2) a 42-year-old man with cystic splenic mass. The histological and immunophenotypical features of both lesions were classical of MC. Although this lesion is uncommon in visceral organs, the possibility of this rare entity must be kept in differential diagnosis with compatible morphology...

Mesenchymal chondrosarcoma (MC) is a rare variety of chondrosarcoma (CS), which is both clinically unique and histologically distinct compared with conventional CS. Maxillofacial MCs are aggressive, have a tendency for recurrence and significant distant metastasis to lung and bone, and are associated with overall poor prognosis. Histopathologically, it is a biphasic tumor comprising of islands of hyaline cartilage with undifferentiated small round cells. Here, we present an interesting case of MC involving the left half of maxilla along with a brief review of the relevant literature...

Rare cases of metastatic squamous cell carcinoma with chondroid differentiation from esophageal primary have been reported but none from the uterine cervix. Given the rarity of this phenomenon and potential diagnostic pitfall, we present this unusual case. The patient is a 25-year-old woman who presented with shortness of breath. Computerized tomography (CT) showed several lung and pleural-based nodules. CT-guided core biopsy with touch preparations were performed on the pleural-based nodule. The touch preparations showed large, spindle-to-oval shaped cells with pleomorphic nuclei embedded in metachromatic chondroid stroma...

The primary mammary chondrosarcoma corresponds to less than 0,5% of the mammary malignancies. For the period ranging from 1967 to 2014, only 18 cases were reported in the literature. A 41year old woman found a hard nodule on her external right superior quadrant/axillary prolongation through breast self-examination. The vacuum-assisted core biopsy (VACB) revealed "high grade extra-skeletal myxoid chondrosarcoma". A skin-nipple-sparing mastectomy with the insertion of a mammary expander was performed. A protocol of adjuvant radiotherapy was also indicated...
