hemangiopericytoma is a rare vascular tumor observed mostly in adults. it usually presents with a painless slowly enlarging mass. the infantile type with much rarer occurrence has a different course compared to adults. very few case reports have been described in the literature with disease onset in the infancy. the first reported case of infantile hemangiopericytoma of limbs from the middle ea...

Oncogenic osteomalacia is a rare cause that makes abnormalities of bone metabolism. Our case arose in a 47-year-old woman presenting a nasal mass associated with osteomalacia. We excised the mass carefully. After surgery, it was diagnosed as hemangiopericytoma and her symptoms related with osteomalacia were relieved and biochemical abnormalities were restored to normal range. We report and revi...

Intracranial hemangiopericytoma is unusual, and those occurring in the posterior fossa is extremely rare; we report such a rare case of hemangiopericytoma of the posterior fossa. The radiologic findings and gross characteristics of hemangiopericytomas are sometimes quite similar to those of meningiomas. Although extremely rare, the operator should be aware of the existence of this disorder to d...

Glomangiopericytoma, also referred to as a hemangiopericytoma-like tumor or sinonasal type hemangiopericytoma, is a rare tumor of the nasal cavity and paranasal sinus that has never been reported in the spinal cord. Here, we report a case of a 47-year-old man who developed glomangiopericytoma in the thoracic spine. This lesion showed a heterogeneous high signal intensity compared to the spinal ...

Meningeal hemangiopericytoma (HPC) is a rare tumor in the central nervous system. It is often reported as “Meningioma”. Unlike meningiomas, HPC has a high rate of local recurrence and distant metastasis, which may occur several years after initial treatment [1]. The purpose of this article is to report a case of parasagittal hemangiopericytoma with delayed multiple extracranial metastases and l...

These tumors are usually located in the musculoskeletal system, retroperitoneum and the skin. Their intracranial...

Hemangiopericytomas, which arise from cells (pericytes) that are wrapped around the pericapillary arterioles, are commonly located in the soft tissue of the thigh and retroperitoneum. Hemangiopericytoma in the mediastinum is extremely rare. Fewer than 20 cases were reported and while one fourth of them was benign and the remainder was malignant. The malignant potential of hemangiopericytoma is ...

An intranasal glomus tumor and a sinonasal hemangiopericytoma-like tumor are reported. Both patients were elderly women suffering from nasal bleeding, and presented with a polypoid mass arising in the nasal septum. Microscopically, the glomus tumor displayed a proliferation of uniform rounded or cuboidal epithelioid cells arranged in sheets and interrupted by a rich vasculature with a character...

Aims. We report on the unusual case of a 43-year-old man who developed recurrent meningeal hemangiopericytoma and presented with hypoglycemia 6 years after excision of the tumor. Methods and Results. We utilized computed tomography to assure multiple tumor metastasis and cranial recurrence of previous meningeal hemangiopericytoma and clinical laboratory tests and immunohistochemical staining to...

BACKGROUND Hemangiopericytoma is a rare mesenchymal neoplasm, accounting for about 1% of vascular tumors The tumor occurs most commonly in the skin, subcutaneous soft tissues, muscles of the extremities, retroperitoneum but rarely in the lung, trachea or mediastinum. CASE PRESENTATION A rare case of primary mediastinal hemangiopericytoma is presented. A 72-year-old woman was treated by comple...
