BACKGROUND Myositis ossificans is localized inflammatory process affecting skeletal muscles. Very rarely it can affect one of the neck muscles and present as a neck tumor, it can be misdiagnosed as the clinical, radiological and histological examinations can mimic a sarcoma. CASE REPORT We report a 29 year old female patient with neck tumor suspected to be a sarcoma who underwent full diagnos...

The i.m. injection of dimethyl sulfoxide prior to the infection of quail with Rous sarcoma virus strain 0 and of mice with Moloney sarcoma virus resulted in increased virus titers, decreased incubation time to tumors and, in the case of Moloney sarcoma virus, decreased spontaneous regressions. Dimethyl sulfoxide administered at the time of or after infection was without effect. This compound al...

pancreatic neuroendocrine tumors (pnet) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. however, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. pnets can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. skeletal muscle metast...

A report of alveolar soft part sarcoma metastatic to the small bowel is presented. Hematogenous metastases to the small bowel from primary tumors outside the abdominal cavity are uncommon, and most remain asymptomatic and are not discovered until autopsy. However, small bowel metastases can lead to intestinal obstruction, intussuseption or even perforation. While metastases to the small bowel h...

introduction: ewing’s sarcoma is the second most common primary malignant tumor of bone found in children after osteosarcoma. it accounts for 4–9% of primary malignant bone tumors and it affects bones of the skull or face in only 1–4% of cases. hence it rarely affects the head and neck. subject and method: in this case report, we describe a case of primary ewing's sarcoma occurring in the tempo...

Sarcomas are rare tumors account for about 1% of cancers in adult. Soft tissue sarcomas are the most common one. Synovial sarcoma's incident is about 10% of all sarcomas and most commonly rise from para-articular regions in young adults. Based on our knowledge there have been only two reports of thyroid synovial sarcoma in medical literature. We report a 44-year old woman presented with a rapid...

Granulocytic sarcoma may develop at any time during the course of acute or chronic myelogenous leukemia. Symptomatic because of their invasive nature and mass effect, these tumors may occur in any anatomic site. Granulocytic sarcoma is diagnosed in a minority of patients with myelogenous leukemia, but when present, granulocytic sarcoma commonly affects the CNS. The most common manifestation of ...

Synovial sarcomas are generally deep-seated tumors that most often occur in the proximity of large joints of adolescents and young adults. We describe two cases of primary renal synovial sarcoma that were treated successfully by radical nephrectomy. Synovial sarcoma originating from the kidney is extremely rare and the histogenesis is uncertain. Surgical resection and ifosfamide based chemother...

The pl6INK4a/MTS1 (p16) gene encodes a specific inhibitor of cyclin-dependent kinase (CDK)4 and CDK6. The p16 gene is frequently mutated or deleted in many types of cancer cell lines as well as in certain types of primary tumors. p16 knockout mice are viable but predisposed to sarcoma and B-cell lymphoma. To investigate the role of p16 in human soft-tissue sarcoma tumor progression, we examined...

Objective: Soft Tissue Sarcomas are rare mesenchymal tumors with many subtypes. Clean margin wide resection is recommended for treatment.In this study, the location, histopathological features, clinical and demographic recurrence prognosis of retroperitoneal sarcomas were investigated. Methods: The demographic, immunohistochemical data 18 patients who operated on diagnosis mass between March 20...
