Abstract: Hemangiopericytoma is a rare vascular tumour of infants. Although generally considered to be benign, local recurrence and metastases can occur. Herein, we report on two full term girls, delivered with lumbosacral swelling and left thigh swelling respectively. Complete surgical excision with safety margins was performed for each lesion. Histologic examination of both lesions showed picture of infantile hemangiopericytoma. There is no evidence of local recurrence or distant metastasis during last 20 and 17 months for 1st case and 2nd case respectively. In conclusion; most infantile hemangiopericytoma follow a benign course. Rarely these tumours behave aggressively with local infiltration, recurrences and even distant metastases. Careful follow up is therefore essential.
Hemangiopericytomas of the spine: case report and review of the literature
Chad D. Cole,Meic H. Schmidt
Rare Tumors , 2009, DOI: 10.4081/rt.2009.e43
Abstract: We describe a rare case of a primary intracranial meningeal hemangiopericytoma (HPC) with late metastasis to the cervical spine. A 36-year-old woman had a left occipital lesion that was histopathologically identified as HPC. Fourteen years after resection, the tumor recurred and was treated with radiotherapy. Three years later, CT imaging showed a large mass in the liver consistent with metastatic HPC, and MRI of the cervical spine showed an extensive lesion of the C3 vertebral body. The patient underwent C3 corpectomy with en-bloc tumor removal and follow-up radiation with no local recurrence or other spinal metastasis for the following 4 years. Regardless of the subtype of spinal HPC, complete surgical removal and radiotherapy appear to be treatment of choice.

Abstract: A 42-year-old male with a history of recurrent intracranial hemangiopericytoma presented to the Emergency Department with urinary retention. Ensuing work-up revealed a 10-centimeter circumscribed pelvic mass that appeared anatomically distinct from the sacrum. This metastasis was found 10 years after the initial resection of his intracranial lesion. An abdominal resection was performed, and the patient recovered uneventfully. Final pathology and staining findings were consistent with metastatic hemangiopericytoma. Hemangiopericytoma is a rare mesenchymal soft tissue neoplasm with potential for late local recurrence and metastasis. Here, we review the case and discuss the clinical relevance of narrowing the diagnosis to HPC or the growing umbrella of Solitary Fibrous Tumor (SFT). To our knowledge, this is the first report of intracranial HPC metastatic to the pelvis.

Advances in Computed Tomography (ACT) , 2013, DOI: 10.4236/act.2013.24022
Abstract:

We present a case report of a 65-year-old woman who underwent resection of a chest wall tumor. In contrast with computed tomography, the tumor exhibited hypervascularity and was fed from the 9th intercostals artery. Histologically, the tumor was diagnosed as a cellular variant of solitary fibrous tumor of the pleura, with branching “staghorn” vessels and hypervascularity. The tumor thus resembled a chest wall hemangiopericytoma.

Abstract: Spinal hemangiopericytomas are rare tumors. To date, only 80 cases of spinal hemangiopericytomas have been reported in the literature. The postoperative evolution of this condition in rare cases can be complicated by a symptomatic compressive epidural hematoma that can be the source of serious neurological complications requiring emergency surgery. We report a rare case of intradural and extramedullary spinal hemangiopericytomas with favorable evolution after treatment in an 82 years old woman.
Recurrent Sinonasal Hemangiopericytoma: A Rare Case Report  [PDF]

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2020, DOI: 10.4236/ijohns.2020.91003
Abstract: Hemangiopericytoma (HPC) is a rare vascular tumor arising from capillary pericytes. This tumor represents 3% - 5% of all soft tissue sarcomas and 1% of all vascular tumors. Only 15% - 30% of cases occur in the head and neck region, among which sinonasal hemangiopericytoma (HPC) is accounted for around 5% of cases. Hemangiopericytoma (HPC) has a tendency for recurrence. Here, a case of recurrent nasal hemangiopericytoma (HPC) after 12 years of treatment is reported.

Abstract: canine hemangiopericytoma is a relatively common cutaneous tumor frequently affecting the limbs. treatment usually is local resection, limb amputation and radiation, with high rates of tumor recurrence. the medical records of 6 dogs treated at the veterinary teaching hospital of the university of s?o paulo between july 1994 and july 1996 were reviewed for tumor features, skin flap technique and postoperative follow up. the dogs in this study were 3 females and 3 males; the mean age was 9 years. one dog was mixed breed and the other dogs were poodle (2); boxer (1); german shepherd(1) and pekingeese(1). the majority of tumors (5 tumors) were located on the limbs and l was located on the perineal region. skin flap techniques used were : h- plasty (2), w-plasty(1), transposition flap (2), single pedicle advancement flap (1). the sutures were removed 10 to 15 days after surgery. five dogs had 100% viability of flap skin and necrosis ocurred in one dog which had a survival of 89% of the flap. one dog died 15 months after the surgery because of nontumor related causes. no evidence of recurrence was noted and tumor free interval ranged from 4-20 months. wide surgical excision of the canine hemangiopericytoma seems to be an eficient therapy since no recurrence ocurred. familiarity with techniques of skin flap creation can provide the surgeon with alternatives to close a large wound resulting from tumor excision. skin flaps can bypass many problems in open wound management including delayed healing and greater expenses.

Abstract: we report a 41-year-old male presenting with progressive dyspnea lasting one month. a cat scan disclosed a left atrial mass, that was surgically excised. the pathological study of the surgical piece showed a primary hemangiopericytoma. one month later, the patient consulted for cervical pain and a positron emission tomography showed multiple metastases. the patient died two months later.

Abstract: Hemangiopericytoma is a vascular tumor that is rarely seen inthe nose and paranasal sinuses. Biological behavior of thesetumors is not completely known, and their natural history isnot predictable. This case report presents a patient with a sinonasalhemangiopericytoma. Diagnosis and management ofthese uncommon tumors is discussed.

Indian Journal of Ophthalmology , 2007,
Abstract: Background: Eyelid malignancies are completely treatable if detected early. The treatment depends on the invasiveness of the cancer which in turn depends on the type of malignancy. Aim: The aim of the study was to characterize the distribution of the types of eyelid malignancies in central India. Settings and Design: The study was conducted in the Department of Plastic and Maxillofacial Surgery at a tertiary care hospital. Materials and Methods: We report a series of 27 cases of eyelid malignancies. In the same case series, we also include a case of malignant hemangiopericytoma which is an extremely rare form of eyelid malignancy worldwide. Statistical Analysis: Depending on the underlying statistical distribution, either analysis of variance (ANOVA) or the Kruskal-Wallis (K-W) test was used to assess the differential distribution of these variables across the types of eyelid malignancies observed in this study. Results: We observed that sebaceous cell carcinoma (~37%) was almost as prevalent as basal cell carcinoma (~44%) in the study subjects and had an earlier age of occurrence and a more rapid clinical course. Conclusions: Sebaceous cell carcinoma of the eyelid is almost as common as basal cell carcinoma in a large tertiary care centre in central India.
