To describe one case of myopericytoma in nasal cavity. We present a case of an adult patient, of the female sex, with complaints of nasal obstruction, pain hemangiopdricitoma the nasal cavities region and eventual epistaxis in the right nasal cavity, which present an angiomatous and easily bleeding, non-pulsatile mass occupying all the right nasal cavity.
The myopericytomas are uncommon vascular tumors, rarely located in the nasal cavity and in the paranasal sinuses. They must be included in the differential diagnosis of the well delimited, vascular and slow growth masses upon computed tomography. Myopericytoma in Nasal Cavity. How to cite this article. The glomic tumor is an uncommon neoplasm hemangiopeticitoma from neuromyoarterial hemangiopericotoma glomic cells. The occurrence in the nasal and paranasal cavities is rare 2.
Histologically, the hemangiopericytomas present blood vessels branched with thin walls and reticuline pericellular fibers. However, it’s been shown that mesenchymal neoplasms of several differentiation lines have been fitting into this definition, and the term “hemangiopericytoma” is characteristic of a morphologic standard of growth rather than a distinct clinicopathological entity 1. In fact, a group of lesions formerly called hemangiopericytomas represents cases of myopericytomas, which show a radial and perivascular arrangement of ovoid neoplastic cells that range from voluminous fusiform to round, which are called myopericytes myocytes 1, 3, 4.
Then she presented with complaints of persistent nasal obstruction, pain in the nasal cavities region and eventual epistaxis in the right nasal cavity which had been worsening for about 8 months.
Upon the anterior rhinoscopic exam, we observed a friable angiomatous and easily bleeding, non-pulsatile mass that occupied all the right nasal cavity. The tomographic exam verified a concealing by soft tissue density material across the right nasal cavity. We opted hemngiopericitoma the performance of incisional biopsy of the lesion through the right nasal cavity with a cutting instrument after topical anesthesia with a solution of neotutocaine and vasoconstrictive agent with anterior splint with cotton wet in a vasoconstrictive agent.
About ten days after the material collection, the biopsy result confirmed myopericytoma. On the 20th of Septemberwe carried out an arteriographic study that confirmed a well-vascularized, delimited mass that occupied the entire right nasal cavity.
With such information, we opted for the accomplishment of embolization ten days before the endoscopic surgical procedure.
On the first of Novemberwe carried out an endoscopic nasosinusal surgical intervention under general anesthesia, by removing the right nasal cavity lesion that was pediculated in the postero-superior septum mucosa.
The patient evolved well without any postoperative bleeding and so far presented an excellent evolution without symptoms. In spite of being rare, the myopericytomas must be hemangiopericitomx in the differential diagnosis of the well delimited masses upon tomography. The angiographies show these tumors are widely vascularized 5. They affect more frequently middle-aged adults and may locate in the dermal or subcutaneous tissue preferably through the distal portion of the extremities 6.
The clinical picture depends on the location and size and may cause nasal obstruction and epistaxis when in the nasal hemangiopericitima 2. Most myopericytomas behave in a benign manner painless and of slow hemangiopericiitoma ; however, uncommon cases of malignant myopericytoma have been reported lately and these are more aggressive cases 1, 6. Cox and Giltman 4 reported a case in the thoracic vertebrae that caused osseous lysis.
Its treatment is surgical 6and may, like the nasoangiofibroma be carried out endoscopically or by open access 8. Today it’s important to carry out the selective tumoral embolization before all the techniques to make the surgical access easier.

The endoscopic technique is an excellent option, because besides being less aggressive, we observe a lower morbidity, minimum bleeding, shorter time of hemangiopericjtoma and higher efficacy, in addition to less trans and postoperative complications 8.
