Spindle cell sarcoma (SCS) of the heart is a rare tumor which has malignant course, that could be primary or metastasis.

Objective NA. Background Design/Methods Results Primary CNS histiocytic sarcoma is a rare hematolymphoid malignancy with features of mature histiocytes and carries poor prognosis. We describe unique case in which 50-year-old woman presented recurrent acute brainstem syndrome, area postrema myelitis corresponding MRI lesions meeting diagnostic criteria for seronegative NMOSD. Despite initial imp...

multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. there was no family history and hereditary syndrome. the genetic analysis was completely normal. to best of our knowledge, t...

Ewing's sarcoma is the second most common primary tumour of bone in childhood. Less frequently it occurs in soft tissues. Ewing's sarcoma/primitive neuroectodermal tumour (ES/PNET) is an extra ordinarily rare primary tumour in the kidney. Only very few cases of primary renal Ewing's sarcoma have been reported in the literature to date. We present a case of primary right renal Ewing's sarcoma in...

Introduction: Sarcomas are rare malignancies with aggressive biological behavior. They are categorized into soft and hard tissue types. The main objective of this study was to analyze the prevalence of head and neck sarcomas (HNS) among the Iranian population. Materials and Methods: The pathology files derived from Iran National Tumor Bank of Cancer Institute in Imam Khomeini Hospital, affiliat...

Synovial sarcoma is a rare soft tissue sarcoma that typically arises in the extremities of young adults. We report a case of a 26-year-old pregnant woman with biopsy-proven primary synovial sarcoma of the lung that was treated with chemotherapy with radiographic response. This is only the third documented case of primary pulmonary synovial sarcoma occurring during pregnancy and the first case w...

ewing sarcoma is about 10 % of bone tumours, in the form of lytic, sclerotic and mixed type. the lytic type erodes the whole bone in such a way that the auther would like to name it 'vanishing' type and recognition of this radiological type is of great importance from differential point of view in the study of primary and secondry tumours of bones.

Primary cardiac synovial sarcoma is an extremely rare entity. The clinical and pathologic characteristics are still poorly understood, and prognostic factors influencing overall survival are still unknown. In the present study, all characteristics of reported patients, including sex, age, clinical presentations, laboratory tests, electrocardiogram, imaging findings, pathology, location, therapy...

Primary malignant lesions of the heart are rare. Although myxomas have been extensively described, there is a paucity of large studies on non-myxomatous cardiac tumours. On the other hand, there are several case reports on specific histopathological variants, in small numbers. Consequently there exists no consensus on therapeutic modalities for cardiac sarcomas. The prognosis for these lesions ...
