Non-transforming helper viruses were isolated from pools of two hamsterspecific sarcoma viruses in which isolations by terminal dilution procedures had previously been unsuccessful. This presumably resulted from approximately equivalent levels of sarcoma and helper viruses in the original pools. Helper virus was isolated from morphologically normal cells selected from tissue culture plates show...
BACKGROUND Synovial sarcoma represents one of the most frequent malignant tumours of soft tissues. Its prognosis is poor because of chemoresistance and high metastatic potential. Improvement of synovial sarcoma outcome requires well-characterized animal models in which to evaluate novel therapeutic options. The aim of this study was to establish a reproducible synovial sarcoma model in athymic ...
The association of mycosis fungoides and kaposi's sarcoma in HIV-negative patients is a rare phenomenon. The presence of human herpesvirus 8 (HHV-8) - associated with all forms of Kaposi's sarcoma - has also been recently identified in mycosis fungoides lesions. However, a causal association between HHV-8 and the onset of mycosis fungoides has not been established yet. The present case reports ...
Sarcomas constitute less than 1% of all cervical malignancies. With over 150 reported cases, rhabdomyosarcomas represent the most commonly reported sarcoma at this location. In this report, a select group of the more uncommon sarcomas of the uterine cervix are reviewed, including all previously reported examples of leiomyosarcoma, liposarcoma, alveolar soft part sarcoma, Ewing sarcoma/primitive...
Primary penile sarcoma is an extremely rare condition. The incidence of penile sarcoma is described as 0.6 to 1 out of 100,000 patients in developed countries, and leiomyosarcoma is the predominant histological type. Given such a low incidence, treatment for this condition is very controversial. The authors could not find in the literature any other case of penile sarcoma with such histological...
Neuronal intermediate filament inclusion disease and atypical frontotemporal lobar degeneration are rare diseases characterized by ubiquitin-positive inclusions lacking transactive response DNA-binding protein-43 and tau. Recently, mutations in the fused in sarcoma gene have been shown to cause familial amyotrophic lateral sclerosis and fused in sarcoma-positive neuronal inclusions have subsequ...
BACKGROUND Synovial sarcoma is a rarely encountered soft tissue sarcoma. Surgery with a wide surgical margin is the treatment of choice. However, there is no consensus on the treatment of head and neck synovial sarcoma in patients with cervical metastasis. METHODS A 20-year-old man was seen with a palpable mass in the right neck. He had been diagnosed with synovial sarcoma of the right tonsil...
BACKGROUND Granulocytic sarcoma is an extramedullary tumor of myeloblasts. The purpose of this report was to present a case of a primary laryngeal granulocytic sarcoma and review of the literature. METHODS A literature review was performed using Medline and PubMed databases to search for cases of all primary and secondary myelogenous tumors of the larynx. RESULTS A 36-year-old man presented...
Myxoinflammatory fibroblastic sarcoma is a rare sarcoma that develops in patients of all ages, which usually presents as a slow-growing painless mass in the distal extremities. To date, myxoinflammatory fibroblastic sarcoma with invasion of the brachial plexus has rarely been reported in the literature. In this study, a case of large cervicothoracic sarcoma, which invaded the brachial plexus, i...
Kaposi's sarcoma is an unusual tumor principally affecting the skin of the lower extremities. Although the association between Kaposi's sarcoma and renal transplant has been well documented, there are few Kaposi's sarcoma cases in the literature associated with ulcerative colitis or other inflammatory bowel diseases. This report presents a patient with ulcerative colitis who developed Kaposi's ...
