“…Therefore, when comparing the treatments of isolated surgery, isolated radiotherapy and combination of surgery and radiotherapy, the treatment modality showed no significant impact on the disease specific survival in 5, 10 and 20 years of head and neck HPC, but has an impact on other hemangiopericytoma [27].…”

The hemangiopericytomas (HPCs) are rare tumors of the dural base and correspond of less than 1% of all primary Central Nervous System (CNS) tumors. It usually affects adult males with 40 to 50 years old and has a supratentorial location (70%), followed by posterior fossa (15%) and spine (15%). Generally, it has fast progression and manifests clinically through headache, focal neurological deficits and epileptic seizures. The tumor has high incidence of local recurrence, from 34% to 90%, and it is estimated that the follow-up of these patients should be done for at least 7, 5 years. The percentage of longdistance metastases is lower, 12% to 55%, affecting especially bones, lungs and liver, in decreasing order. The objective of this study is to evaluate the contradictions when approaching these tumors and to analyze a rare case of pediatric involvement. It was prepared a case report and a literature review was made using the data bases MEDLINE®, PubMed and Cochrane, where 31 relevant articles were selected related to the proposed study. The outcome of HPC treatment can change according to the tumor's location in the CNS or extracranial, the tumor's size and the histopathological classification. Therefore, many studies have been proposed observing the answer of the surgical resection, the adjuvant radiotherapy, the radiosurgery and the antiangiogenic therapies.

“…It is important to say that isolated surgical procedures are primary modalities, so that radiotherapy must have more studies in order to truly show its role. It should be considered in cases of positive or uncertain surgical margins [27]. The hemangiopericytoma is a hypervascular sarcoma of body's soft tissues.…”

“…Following recurrence of her SFT/HPC many years later, the histology of her tumor had changed significantly, with greater than 5 mitoses per high powered field and involvement of the calvarium. Though increased mitotic activity is associated with more aggressive clinical behavior [1] , [2] , [3] , even low-grade tumors with bland histology have malignant potential and require surveillance for distant metastases [9] .…”

“…Hemangiopericytoma or solitary fibrous tumors (SFT/HPC) are rare mesenchymal tumors that often present as a painless mass most commonly arising from the abdomen and pleura, though they can also be found in the extremities, head and neck or trunk, and central nervous system. Although the majority of these tumors exhibit benign behavior and have a good prognosis, physicians must be aware that a minority of patients with these slow-growing tumors are at risk for local recurrence and distant metastases [1] , [2] , [3] . Here, we present an unusual case of cervical paravertebral SFT/HPC with both local recurrence and widespread metastatic disease detected by fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT).…”

Solitary fibrous tumors/hemangiopericytomas (SFT/HPC) are soft tissue tumors that can arise from the abdomen, pleura, head and neck, or extremities. We report an unusual case of recurrent hemangiopericytoma in a 67-year-old female presenting with a painless and palpable mass within her right posterior neck. Eight years after initial resection of the mass, a follow-up MRI showed multiple enlarging calvarial lesions. A whole body FDG-PET/CT revealed not only hypermetabolic calvarial lesions but also numerous hypermetabolic axillary node and osseous metastases. Though the majority of these soft tissue tumors exhibit benign behavior and carry a favorable prognosis, patients with these slow growing tumors are at risk for local recurrence and distant metastases which demonstrate substantial FDG avidity. Additional studies are needed to clarify the role of whole body FDG-PET/CT in the surveillance of SFT/HPC to detect recurrent or metastatic lesions.

“…. Current consensus regarding the treatment of hemangiopericytoma is wide, radical surgical excision with the radiotherapy follow-up if the tumor shows malignant characteristics25 . We performed wide surgical excision, with extirpation of the tumor in full and radical resection to clean edges, without adjuvant radiotherapy, since pathohistological analysis showed benign characteristics of the tissue.…”

Large hemangiopericytoma of the shoulder: A case report

Introduction: Hemangiopericytoma is a rare tumor arised from the pericytes, contractile spindle cells that surround the capillaries and post-capillary venules. The tumor was found equally among males and females. Case report: We report a case of a 63-year-old female who presented a giant painful mass on her right shoulder that occurred one year before admission. Limited range of motion and a sense of tingling along the affected arm was present also. An irregular, oval-shaped mass, colored dark-red, with signs of necrosis was the maximal diameter of 14cm. Routine laboratory analyzes showed results within the range of referenced values. Lung X-ray and ultrasonographic examination of the abdomen showed no signs of secondary tumor deposits, and no osteo-muscular lesions in the affected region. Ultrasonographic examination of the neck and right axillary region showed no signs of regional metastases. The surgical excision of the entire tumor was performed, with the associated subcutaneous tissue and a part of fascia underneath. Results of the histopathological analysis confirmed the diagnosis of hemangiopericytoma. The specimen showed no signs or elements of the neoplastic tissue on the edges of the resection lines. 3 years after the operation, there was found no signs of tumor relapses, regional or systemic metastases. Conclusion: Considering that there are no official clinical guides and protocols for hemangiopericytoma management, as well as the occurrence of cutaneous and subcutaneous hemangiopericytomas is exceptionally rare, more extensive research in this field and more described cases are need to gain a better understanding of that issue.
