hemangiopericytoma/nausea

We report a 29-year-old woman who presented with severe headache, nausea and vomiting. A lesion was found in the left petrous ridge and near-total resection was performed. Pathologic examination showed anaplastic hemangiopericytoma (World Health Organization Grade III). Hemangiopericytoma is an

BACKGROUND Hemangiopericytomas are rare intracranial neoplasms that generally occur in the fifth decade of life and are commonly dural-based, supratentorial tumors. They are classified as World Health Organization grade II or III because of their aggressive nature with high rates of local recurrence

Background: Intracranial solitary fibrous tumors/hemangiopericytomas (ISFTs/HPCs) are extremely rare spindle-cell tumors that are mostly benign and derived from mesenchymal tissue. Extracranial metastasis and intratumoral hemorrhage are considered to be special

The objective of this phase II study was to evaluate the efficacy and safety of subcutaneous octreotide therapy for the treatment of recurrent meningioma and meningeal hemangiopericytoma. Octreotide is an agonist of somatostatin receptors, which are frequently expressed in meningioma, and reports

Objective: To investigate the clinical manifestations, imaging features, clinicopathologic features, and differential diagnosis of solitary fibrous tumors/anginoblastomas (SFT/HPCs) originating in the central nervous system. Methods: Sixty cases of SFT/HPCs originating in the central

BACKGROUND The Inflammatory fibroid polyp (IFP) is a mesenchymal polypoid lesion of the gastrointestinal tract that follows a benign course. Incidence is extremely low: from 0,1% to 2 %. Histologically, it consists of a sub mucous proliferation of vascolarized fibromuscolar tissue with a high

BACKGROUND Osteoblastoma is an uncommon primary bone tumor that involves any part of the skeleton. But its occurrence in the skull is extremely rare. UNASSIGNED A 30-year-old female was admitted to our hospital, because of the mass in the right frontal region with the history of headache for 3 years

A 61-year-old male presented with a recurrent solitary fibrous tumor (SFT) arising from the falx cerebri with intraventricular extension manifesting as nausea and vomiting. Magnetic resonance imaging showed the heterogeneously enhanced tumor in the falx, which extended to the bilateral lateral

This paper reports a case of glomus tumor of stomach from a male patient, 58 years old, with the chief complaint of nausea and vomiting after meal. This tumor was at the anterior wall of the antrum near the lesser curvature. By light microscopy, it was composed of glomus tumor cells and abundant

BACKGROUND Phenylbutyrate (PBA), and its metabolite phenylacetate (PAA), induce growth inhibition and cellular differentiation in multiple tumor models. However, despite their potential anti-cancer properties, several pharmacodynamic aspects remain unknown. METHODS We conducted a dose escalating

BACKGROUND Intracranial malignant solitary fibrous tumor (MSFT) is extremely rare. The authors report a case of MSFT of the right occipital lobe with a rapid recurrence and bilateral lung, multiple bone metastasis. METHODS The patient was a 25-year-old male presenting with headache, nausea and

Thirty-six children and adolescents received 42-h methotrexate (MTX) infusions in doses of 5.5-22 g/m2 as a single drug or as part of a combination chemotherapy for relapsed childhood leukemias or solid tumors. In a total of 109 courses serum MTX concentrations were maintained at 2 x 10(-5) -2 x

BACKGROUND Meningiomas are common intracranial neoplasms of undetermined etiology. Accelerated growth during episodes of elevated serum estrogen and progesterone have been demonstrated in pregnant patients, as exhibited by an overexpression of estrogen or progesterone on immunohistochemical
