However, the information concerning its natural history remains unclear. In this report, we presented a patient with parapharyngeal SFT/HPC, who was not immediately treated with surgical resection at first diagnosis. Read More

Nasal hemangiopericytoma presenting with oncogenic osteomalasia: A case report and literature review.

Curr Probl Cancer 2021 Jun 8;45(3):100704. Epub 2021 Jan 8.

Trakya University School of Medicine, Department of Internal Medicine, Division of Medical Oncology, Edirne, Turkey.

Sinonasal type hemangiopericytoma is a rare soft tissue tumor. Oncogenic osteomalacia (tumor-induced osteomalacia) is a rare syndrome that develops especially due to benign mesenchymal tumors. Nonspecific general bone pain and weakness delay the diagnosis and treatment of oncogenic osteomalacia, and it is difficult to determine the localization of the primary tumor causing oncogenic osteomalacia.

Case Rep Oncol 2020 Sep-Dec;13(3):1393-1396. Epub 2020 Nov 30.

Department of Medicine (Oncology), Stanford University School of Medicine, Stanford, California, USA.

Ewing's sarcoma is a rare and aggressive tumor that typically arises in the long bones of the extremities. It belongs in the family of small round blue cell tumors and is characterized immunohistochemically by diffuse CD99 expression and molecularly by one of several oncogenic translocations, most commonly t(11;22)(q24;q12) between the gene and the gene. Here we present a rare case of Ewing's sarcoma in the sinonasal tract with gene arrangement that was regarded for almost a decade as a sinonasal-type hemangiopericytoma (glomangiopericytoma).

Department of Clinical Oncology and Chemotherapy, Nagoya University Hospital, Nagoya, Japan.

Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a rare tumor derived from mesenchymal tissue. Although standard chemotherapy for SHT/HPC has not been established, temozolomide plus bevacizumab (TMZ+Bev) therapy for SFT/HPC has been reported. The effectiveness and safety of TMZ+Bev (temozolomide 150 mg/m orally on days 1-7 and days 15-21 and bevacizumab 5 mg/kg intravenously on day 8 and day 22 on a 28-day cycle), which was administered from December 2013 until April 2019 to four patients with SFT/HPC, were retrospectively analyzed.

[Immunohistochemical analysis for the diagnosis of solitary fibrous tumor/ hemangiopericytoma].

Medicina (B Aires) 2020 ;80(6):729-733

Departamento de Neurología, Centro Universitario de Neurooncología, Instituto de Oncología ángel H. Roffo, Facultad de Medicina, Universidad de Buenos Aires, Argentina.

The solitary fibrous tumor/ hemangiopericytoma (TFS/HP) is a rare mesenchymal extraaxial tumour. TFS/HP can sometimes be difficult to distinguish from other extra-axial tumors like meningioma, which can be clinically and radiologically indistinguishable. Molecular analysis with STAT6 (signal transducer and activator of transcription 6) nuclear expression or NAB2-STAT6 (NGFI-A binding protein 2) fusion is recommended to confirm the diagnosis.

Grade III Solitary Fibrous Tumor/Hemangiopericytoma: A Rare Case of a World Health Organization Grade III Anaplastic Hemangiopericytoma.

Cureus 2020 Oct 13;12(10):e10926. Epub 2020 Oct 13.

Radiology, University of Florida College of Medicine, Jacksonville, USA.

Solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) have been combined into a single designation in the most recent World Health Organization (WHO) guidelines as solitary fibrous tumor/hemangiopericytoma (SFT/HPC). These rare intracranial tumors can present as WHO grade I, II, or III tumors, with the risk of recurrence, metastasis, and mortality worsening with higher-grade tumors. We present a case of a patient with a WHO grade III SFT/HPC with an emphasis on the imaging features that help differentiate this type of tumor from meningiomas, which are much more common and can appear similar.

A Rare Case of a Primary Spinal Solitary Fibrous Tumor/Hemangiopericytoma in a 9-Month-Old Patient.

Am J Case Rep 2020 Nov 7;21:e923176. Epub 2020 Nov 7.

Department of Diagnostic Radiology, University of Puerto Rico School of Medicine, San Juan, Puerto Rico.

BACKGROUND Solitary fibrous tumors (SFTs)/hemangiopericytomas (HPCs) are mesenchymal tumors commonly found in middle-aged patients, usually localized to thoracic pleurae. Spinal tumor involvement is rarely seen, and its imaging findings are largely inconsistent because of the rarity of these cases. We present a case report of a 9-month-old girl with a rare intraspinal tumor with histologic evidence of SFT/HPC, but no STAT6 nuclear immunoreactivity. Read More
