Histologic assessment of peritumoral edema in soft tissue sarcoma.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To evaluate whether satellite tumor cells can be identified histologically in the tissues surrounding a soft tissue sarcoma and whether their presence correlates with increased T(2)-weighted signal intensity on MRI. METHODS Fifteen patients with a high-grade extremity or truncal soft

Next-generation sequencing of idiopathic multicentric and unicentric Castleman disease and follicular dendritic cell sarcomas.

Numai utilizatorii înregistrați pot traduce articole

Castleman disease (CD) is a rare lymphoproliferative disorder subclassified as unicentric CD (UCD) or multicentric CD (MCD) based on clinical features and the distribution of enlarged lymph nodes with characteristic histopathology. MCD can be further subtyped based on human herpes virus 8 (HHV8)

Photofrin photodynamic therapy for treatment of AIDS-related cutaneous Kaposi's sarcoma.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Kaposi's sarcoma, the most common malignancy in AIDS patients, often presents with painful cutaneous lesions that are difficult to treat effectively despite a wide variety of therapeutic approaches. We used photodynamic therapy in an attempt to provide effective palliative treatment for

Involvement of vascular endothelial growth factor in Kaposi's sarcoma associated with acquired immunodeficiency syndrome.

Numai utilizatorii înregistrați pot traduce articole

To examine the role of vascular endothelial growth factor (VEGF) in the development of edema associated with Kaposi's sarcoma (KS) in acquired immunodeficiency syndrome (AIDS), we exploited animal model systems to detect the activity that induces vascular hyper-permeability (VHP) using cultured

Primary intimal sarcoma of pulmonary valve and trunk with osteogenic sarcomatous elements. Report of a case considered to be pulmonary embolus.

Numai utilizatorii înregistrați pot traduce articole

A 49-year-old woman had a six-week history of increasing shortness of breath and fatigue. X-ray films and pulmonary scans showed multiple areas of emboli, especially in the right lung. Treatment with heparin was unsuccessful, and although a repeat scan showed only slight changes, the patient's

Diacylglycerol kinases are essential for hepatocyte growth factor-dependent proliferation and motility of Kaposi's sarcoma cells.

Numai utilizatorii înregistrați pot traduce articole

Hepatocyte growth factor (HGF) is involved in the pathogenesis of Kaposi's sarcoma (KS), the most frequent neoplasia in patients with AIDS, characterized by proliferating spindle cells, infiltrating inflammatory cells, angiogenesis, edema, and invasiveness. In vitro, this factor sustains the

Aggressive behavior of classical Kaposi's sarcoma and coexistence with angiosarcoma.

Numai utilizatorii înregistrați pot traduce articole

An 82-year-old Caucasian man presented with initially asymptomatic livid red plaques on the plantar surface of the feet that become confluent and evolved into invasively growing nodules accompanied by massive edema. Histology allowed a diagnosis of the classical form of Kaposi's sarcoma; the

[Reaction of cellular-tissue components of osteogenic sarcoma to the combined action of adriamycin and irradiation].

Numai utilizatorii înregistrați pot traduce articole

The study was concerned with the analysis of peculiarities of pathomorphism development in osteogenic sarcoma under different therapeutic modalities. Material was obtained from 229 cases of tumor treated within 1955-1981. Electron microscopic examination of tumor was performed in 20 patients who had

Meningeal alveolar soft part sarcoma confirmed by characteristic ASPCR1-TFE3 fusion.

Numai utilizatorii înregistrați pot traduce articole

Sarcoma metastatic to the brain is uncommon and rarely occurs as the initial manifestation of tumor. Alveolar soft part sarcoma (ASPS) is a rare but well-studied subtype of sarcoma. A 39-year-old man presented with seizures due to a left temporal meningeal-enhancing lesion with striking brain edema

[Radiation Therapy for Management of Soft Tissue Sarcomas].

Numai utilizatorii înregistrați pot traduce articole

Soft tissue sarcomas (STS) are rare malignancies. STS represent a heterogeneous group of tumors, with many of them posing a high risk of local recurrence and distant metastasis. The major therapeutic goals of treating STS are to maximize local tumor control using minimal surgery and to improve

Myeloid Sarcoma of the peritoneum at older ages: A case report and review of literature.

Numai utilizatorii înregistrați pot traduce articole

Myeloid sarcoma or granulocytic sarcoma (GS) is a rare disease with poor prognosis. It is characterized by the occurrence of tumor masses at an extra-medullary tissue. It is composed of myeloblastic cells and usually occurs in association with acute myeloid leukemia. Because of its nonspecific

[A case of myeloid sarcoma in the anterior mediastinum].

Numai utilizatorii înregistrați pot traduce articole

We report a case of myeloid sarcoma in the anterior mediastinum. The patient was a 33-year-old man with a chief complaint of right shoulder pain, right upper limb edema, and cough. Chest contrast-enhanced computed tomography (CT) revealed a partially enhanced anterior mediastinal tumor. A CT-guided

Ecchymotic Kaposi's sarcoma.

Numai utilizatorii înregistrați pot traduce articole

We report two patients with ecchymotic patches that did not suggest the diagnosis of Kaposi's sarcoma. The principal complaint of one patient was facial and periorbital edema with bilateral periorbital ecchymosis. On his trunk were patches resembling pityriasis rosea-like Kaposi's sarcoma. Both

Control of vasogenic edema in a brain tumor model: comparison between dexamethasone and superoxide dismutase.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE The production of prostaglandin (PG) within brain tumors probably generates excessive amounts of oxygen free radicals that may disrupt microvessel permeability within the tumor and in the adjacent brain. We evaluated the effect of systemic therapy with recombinant human
