Primary Ewing's sarcoma is an uncommon lethal tumour of the long bones and pelvic girdle mainly affecting children and young adults. An origin in the cranial bones is extremely rare. We report a unique case of primary involvement of the greater wing of sphenoid bone in a 16-year-old patient.

Bone tumours are comparatively uncommon, constituting only 0.5% of the total world cancer incidence. As Bone tumors consist of several distinct clinico-pathological entities, descriptive epidemiology of tumors at this site can be based only on studies where they can be distinguished. Ewing's sarcoma

We describe a rare case of an extensive primary cranial Ewing's sarcoma located in the greater wing of the sphenoid bone with extension to the orbit, the endocranium, the parapharyngeal and infratemporal space. The patient presented with diplopia, anosmia and prolapse of the left eye. He was given

Angiosarcoma, one of the least common sarcomas, occurs most commonly in the skin and soft tissues, and postirradiation angiosarcoma of the greater omentum is extremely rare. Only one reported case of postirradiation angiosarcoma involved the greater omentum. We describe the case of 74-year-old

Tumor necrosis factor-alpha/cachectin (TNF-alpha) and lymphotoxin (LT, TNF-beta) are primarily products of monocytes and lymphocytes, respectively. The proteins are 51% homologous in their primary structure, cause necrosis of Meth A sarcoma in vivo, are toxic to selected tumor cells in vitro, and

We report a case of myeloid sarcoma with multifocal skeletal involvement, including the greater wing of the sphenoid bone. A 23-month-old boy presented with left-sided proptosis and fevers, and was found to have an infiltrative mass involving the left sphenoid bone on orbital imaging. Full body

A transplantable sarcoma of the fowl, known as Chicken Tumor XVIII, in our series, succeeds better in chickens of an alien breed (Plymouth Rock) than in those of the variety in which it originated (brown Leghorn). This is not due to gross physical differences in the two breeds but to some more

BACKGROUND Granulocytic sarcoma (GS) is an extramedullary disease which is composed of immature myeloid cells or myeloblasts and usually occurs in association with acute myeloid leukemia (AML), as an initial presentation or a relapse. GS has been associated with various cytogenetic abnormalities,

PC12 cells were stably transfected with expression vectors containing rat tissue plasminogen activator (tPA) under control of either a cytomegalovirus or rous sarcoma virus promoter. Cell lines were characterized using protease assays, ELISAs, immunoblots, northern blots, and Southern blots. Control

OBJECTIVE The present study was undertaken to determine factors predictive of toxicity, patterns of failure, and survival in 60 adult patients with soft tissue sarcomas of the extremity and superficial trunk treated with combined perioperative high-dose-rate brachytherapy and external beam

This is the first report demonstrating hormonal control of cAMP levels in Ewing's sarcoma cells. Two classes of hormones, beta-adrenergic agonists and prostaglandins stimulate cAMP production in cultured Ewing's sarcoma cells. The efficacy order for beta-adrenergic agonists is (-)-isoprenaline

Calcitonin gene-related peptide (CGRP) receptor activity was studied in WE-68 human Ewing's sarcoma cells. 125I-human CGRP bound in a time-dependent, reversible and saturable manner. Scatchard plots were compatible with the presence of a homogenous population of CGRP receptors with high affinity (Kd

Hyperthermia greater than or equal to 42 degrees C is tumoricidal in vitro and in many animal models, although such temperatures have only recently been achieved experimentally in some human cancers. A recently developed radio frequency device that provides safe hyperthermia to any depth without

41 uterine sarcoma patients completed their post-operative adjuvant treatment at Istanbul University, Oncology Institute. Of these patients 23 had pelvic irradiation (RT group) and 18 had pelvic irradiation plus chemotherapy (RT + CT group). The 3 year survival rates of the two adjuvant treatment

A series of alkylating and aralkylating bromides was used in a comparative study of chemical reactivity (using 4-(p-nitrobenzyl) pyridine as standard nucleophile), and carcinogenic activity (using single injections by the subcutaneous route in 6-week old female CB-hooded rats). Benzyl, ethyl,
