The efficacy of current standard therapies for the treatment of sarcoma remains limited. With the aim of identifying target antigens relevant to the development of vaccine-based immunotherapy of sarcoma, we have addressed the relevance of tumor-specific antigens encoded by genes belonging to the SSX family as vaccine targets in sarcoma tumors. Expression of SSX-1 to -5 was analyzed in a collect...

High-grade endometrial stromal sarcoma is a rare uterine malignancy. The cells of these tumors resemble endometrial cells in the proliferation stage, with many small plexiform arterioles. Herein we present a patient with endometrial stromal sarcoma that metastasized to the brain, along with the CT and MRI findings and a discussion of the surgical and histopathological features of the metastatic...

BACKGROUND Sarcomas are rare mesenchymally derived tumors for which there are limited treatment options. This paper discusses the current therapeutic potential of directed tyrosine kinase inhibitors (TKIs) in sarcoma. METHODS The authors review antibody-based strategies and small molecular inhibitors of TKIs, with specific emphasis placed on the potential use of these targeted agents as thera...

OBJECTIVE Controversy exists about the treatment outcomes of the Ewing sarcoma family of tumors among low-incidence populations. We evaluated whether Korean Ewing sarcoma family of tumors patients have poorer outcomes than Euro-American patients. METHODS We retrospectively analyzed the clinicopathologic characteristics and outcomes of patients with localized Ewing sarcoma family of tumors tre...

Prostatic sarcoma is a rare and aggressive disease that accounts for less than 1% of all diagnosed malignant prostate tumors. It mainly affects older men its epidemiology still not well defined due to the lack comprehensive registries. The clinical presentation prostatic variable, with urinary symptoms, pelvic or lumbar pain systemic symptoms. Diagnosis requires evaluation including history, ph...

A 73-year-old man complained of sternoclavicular joint pain; blood tests revealed elevated C-reactive protein. The patient developed delirium; magnetic resonance imaging showed metastatic bone tumors. He died two weeks after admission. Autopsy revealed abdominal aortic intimal sarcoma with metastasis to the peritracheal lymph nodes and sternum. Peripheral arterial embolism and bone metastasis a...

Purpose: Ewing sarcoma is a tumor of the bone and soft tissue characterized by diffuse cell membrane expression of CD99 (MIC2). Single-site, surgically resectable disease is associated with an excellent 5-year event-free survival; conversely, patientswith distantmetastases have a poor prognosis.Noninvasive imaging is the standard approach to identifying sites of metastatic disease. We sought to...

SUMMARY Askin tumor is a peripheral neuroepithelioma originating in chest wall. It is a very aggressive tumor and with Ewing's sarcoma are the most frequent tumors of chest wall. The tumor is composed of small round or ovoid cells arranged in sheets with pseudorossette formation. Some times around vessels, glycogen staining is some times positive in H & E but always positive in E.M. In E.M be...
