“…Percutaneous biopsy is not recommended because of the high risk of bleeding. The definitive diagnosis is anatomopathological after analyzing the surgical specimen (6). The distinction between benign or malignant hemangiopericitoma is based on clinical and pathological criteria (7).…”

“…The use of adjuvant radiation therapy has been described for improving local control and reducing recurrences, although it is considered to be a relatively radio-resistant tumor (1,2,9,10). The prognosis is conditional on achieving a complete resection, with five-and ten-year survival rates between 70 and 80%, depending on the series (6). The recurrence rate ranges between 20 and 50% after resection.…”

Background:The hemangiopericytoma is an uncommon vascular tumour. We report a case of interest because of its rarity, size and location.Case report: We present the case of a 63-year-old woman who consulted for abdominal pain. TAC, MRI and arteriography showed a pelvic mass occupying Douglas' space, displacing the uterus, bladder and sigma, with vascularisation relative to the inferior mesenteric artery and both hypogastric arteries. The vascularity of the tumour itself was selectively embolised before the mass was resected. There were no intra-or postoperative complications. Pathology confirmed the diagnosis of hemangiopericitoma. The patient is being monitored as an outpatient, with no signs of recurrence to date.Discussion: The hemangiopericytoma is a tumour of the pericyte cells so it can occur in any location. The pelvic location is exceptional. The tumour may appear as nonspecific abdominal pain, show signs of compression of adjacent organs or occasionally be associated with paraneoplastic syndromes. The diagnosis is suspected via CT and angiography findings, but confirmation is only made by analysing the surgical specimen. The treatment of choice is surgery, in some cases after preoperative embolisation of the vascularisation of the mass. There is no agreement on chemo/ radiotherapy as the primary treatment for hemangiopericytoma, although adjuvant radiation therapy has been found to improve local control and reduce recurrences. The prognosis is good if complete resection is achieved, with five-and 10-year survival rates between 70 and 80%, depending on the series.

“…La mayor parte de los pacientes presentan síntomas derivados del crecimiento del tumor y la compresión que provoca sobre las estructuras vecinas, siendo en general una masa poco dolorosa; estas manifestaciones clínicas suelen ser insidiosas y preceder al descubrimiento del tumor que tiene un lento crecimiento 1,4 . En nuestros casos, el síntoma predominante fue dolor localizado, asociado a síndrome constitucional en el caso 1.…”

“…A pesar de dichos criterios no existe ningún dato fiable para distinguir los TFS malignos, por ello se recomienda el seguimiento a largo plazo de estos pacientes ya que algunas recurrencias ocurren de manera tardía, incluso 10 años después de la neoplasia primaria. Las metástasis suelen asentar en pulmón seguidas de hueso e hígado4,8 . El tratamiento de elección de las recidivas locales y metásta-sis, siempre que sea posible, es la extirpación quirúrgica 1 .En conclusión, el TFS debe ser considerado en el diagnóstico diferencial de las neoplasias de partes blandas, hipervascularizadas que se originen principalmente en pelvis, retroperitoneo y miembros inferiores.…”
