Lester Dr Thompson
One of the most challenging diagnostic categories within tumors of the sinonasal tract is the small round blue cell tumors. Biopsies are usually small and limited, resulting in considerable diagnostic difficulty for practicing surgical pathologists. These tumors share several overlapping histologic and immunophenotypic findings while also showing considerable variation within and between cases. Specific tumor site of origin, imaging findings, and clinical findings must be combined with the histology and pertinent ancillary studies if the correct diagnosis is to be reached...

Bortezomib, formerly known as PS341, is a novel proteasome inhibitor with in vitro and in vivo antineoplastic effects in many malignancies. However, diverse antitumor mechanisms of bortezomib have been identified in many investigations and preclinical studies. Understanding the molecular and cellular mechanisms through which bortezomib acts will improve the therapeutic utility of this drug in different cancer types. In the present study, we investigated the in vitro and in vivo effects of bortezomib on chondrosarcoma...

Cytokines produced in the tumour microenvironment exert an important role in cancer pathogenesis and in the inhibition of disease progression. Cancer of the cartilage is termed metastatic chondrosarcoma; however, the signaling events resulting in mesenchymal cell transformation to sarcoma have yet to be fully elucidated. The present study aimed to characterize the cytokine expression profile in the human JJ012 chondrosarcoma cell line, as well as the effect of cytostatic proline-rich polypeptide-1 (PRP-1). Western blot experiments demonstrated that the levels of suppressor of cytokine signaling 3 (SOCS3) were upregulated in chondrocytes compared with chondrosarcoma cells...

BACKGROUND: Sarcomatoid urothelial carcinoma (SUC) is a rare malignant neoplasm of the urinary bladder comprising 0.2-0.6 % of all histological bladder tumor subtypes. It presents as a high-stage malignancy and exhibits aggressive biological behavior, regardless of the treatment employed. It is defined as histologically indistinguishable from sarcoma and as a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. The mean age of patients presenting with SUC is 66 years, and the male-to-female ratio is 3:1...

BACKGROUND: Rhabdomyosarcoma (RMS) is a malignant tumor of mesenchymal origin and comprises the largest category of soft-tissue sarcomas both in children and adolescents. From a pediatric oncology point of view, RMS has traditionally been classified into alveolar (ARMS) and embryonal (ERMS) subtypes. The anatomical localization of the tumor may vary, but commonly involve the head/neck regions, male and female urogenital tract or the trunk and extremities. CASE PRESENTATION: Here, we report two challenging cases involving 17- and 9-years-olds males where diffuse and multiplex bone lesions suggested either a hematological disease or a primary bone tumor (mesenchymal chondrosarcoma)...

Mesenchymal chondrosarcomas (MC) are rare and aggressive forms of chondrosarcoma. They are distinct tumors arising in unicentric or multicentric locations from both skeletal and extraskeletal tissues. The most affected region is the facial skeleton, especially the jaws. In this report, we present a case of MC primarily involving the mandible in a 60-year-old female patient.

AIM: Luteinizing hormone releasing hormone (LHRH) is a neurohormone, secreted by the hypothalamus, which regulates the secretion of gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) from the pituitary. LHRH acts by binding to receptors located in the pituitary gland. These receptors (LHRH receptors) have also been found in the cytoplasm of many tumor cells that involve both the reproductive and non-reproductive organs. These receptors have been demonstrated in prostate and breast cancers, endometrial carcinomas, renal cell carcinoma, lymphoma, carcinoma of liver, pancreas and skin...

Mesenchymal chondrosarcomas are rare and highly aggressive sarcomas occurring in bone and soft tissue, with poor overall survival. Bcl-2 expression was previously shown to be upregulated in mesenchymal chondrosarcomas. We here report on a newly derived mesenchymal chondrosarcoma cell line, MCS170, in which we investigated treatment with the BH3 mimetic ABT-737 alone or in combination with conventional chemotherapy as a possible new therapeutic strategy. The presence of the characteristic HEY1-NCOA2 fusion was confirmed in the MCS170 cell line using FISH, RT-PCR, and sequencing...

Chondrosarcoma is a malignant tumor of mesenchymal origin predominantly composed of cartilage-producing cells. This type of bone cancer is extremely resistant to radiotherapy and chemotherapy. Surgical resection is the primary treatment, but is often difficult and not always practical for metastatic disease, so more effective treatments are needed. In particular, it would be helpful to identify molecular markers as targets for therapeutic intervention. Endothelin-1 (ET-1), a potent vasoconstrictor, has been shown to enhance chondrosarcoma angiogenesis and metastasis...

Lymph node metastasis of osteosarcomas is a rather rare phenomenon; according to different authors, the incidence of lymph node metastasis is 4 to 11%. The detection of lymph node metastases in osteosarcoma is associated with a significant reduction in the 5-year survival of patients and allows its classification as clinical stage IV tumor. The risk factors for lymph node metastases in patients with bone sarcomas are age (≥64 years), gender (female), nosological entity (undifferentiated pleomorphic sarcoma, osteosarcoma, chondrosarcoma), tumor depth (muscle, bone), and the size of primary tumor (>5 сm)...

Ventricular tachycardia (VT) and premature contraction originating from the right ventricular outflow tract (RVOT) usually appear in healthy individuals. Radiofrequency ablation (RFA) is highly effective at resolving this type of arrhythmia. Refractory VT of RVOT is uncommon and occasionally results from cardiac metastasis of extraskeletal mesenchymal chondrosarcomas (ESMC). ESMC is a rare malignant tumor arising from soft tissues. The current study presents the case of a 25-year-old male with severe VT arising from RVOT due to metastasis of an ESMC that originally occurred in the retroperitoneum...

BACKGROUND: In addition to treating acute promyelocytic leukemia, arsenic trioxide (ATO) suppresses other solid tumors, including chondrosarcoma. However, the effects of ATO on metastasis in chondrosarcoma cells, and the underlying molecular mechanisms remain unclear. METHODS: The effects of ATO on the migratory and invasive capacities of chondrosarcoma cells were investigated by Wound healing, Transwell and EMT assays. The expression of miR-125b in human chondrosarcoma tissues and cell lines was detected by real-time PCR analysis...

BACKGROUND: Intracranial extraskeletal mesenchymal chondrosarcomas (MCSs) are rare tumors accounting for <0.16% of intracranial tumors. They are usually described as occurring in the age group of 20-30 years and are commonly found in the frontoparietal region arising from the falx and surrounding dura. We describe 3 cases at varying ages, locations, and outcomes. CASE DESCRIPTION: A 42-year-old woman with anterior one third falx-based lesion; a 7-year-old boy with mid one third falcine lesion with hyperostosis of bone, presenting in comatose stage; and a 52-year-old woman with left posterior lateral frontal dural-based lesion are presented...

Mesenchymal chondrosarcoma (MC) is an aggressive small round blue cell tumor with chondrogenic differentiation that typically arises in bony sites. Approximately a third of these tumors develop in extra-skeletal sites such as the meninges, and somatic soft tissue. MCs are well-circumscribed, lobulated masses, with focal calcification. Histologically, two distinct populations of neoplastic cells characterize MC: sheets of primitive small, round, blue cells surrounding islands of well-developed hyaline cartilage with mature chondrocytes in lacunae...

Sarcomas are infrequent mesenchymal neoplasms characterized by notable morphological and molecular heterogeneity. Molecular studies in sarcoma provide refinements to morphologic classification, and contribute diagnostic information (frequently), prognostic stratification (rarely) and predict therapeutic response (occasionally). Herein, we summarize the major molecular mechanisms underlying sarcoma pathogenesis and present clinically useful diagnostic, prognostic and predictive molecular markers for sarcoma...
