“…Immunohistochemically, these tumors are positive for vimentin, SMA, muscle specific actin, and factor XIIIa and negative for desmin, CD31, CD34, CD99, CD117, S100 protein, and bcl-2, although they have been weakly positive for CD34 and S100 protein in some cases 5 , 13 , 15 , 17 , 18) . It shows soft tissue density and heterogeneous enhancement on CT 6 , 9 , 13 , 14) . On MRI, an isointense signal (relative to normal nasal mucosa) is observed on T1WI, and an isointense-to-high signal is seen on T2WI.…”

Glomangiopericytoma, also referred to as a hemangiopericytoma-like tumor or sinonasal type hemangiopericytoma, is a rare tumor of the nasal cavity and paranasal sinus that has never been reported in the spinal cord. Here, we report a case of a 47-year-old man who developed glomangiopericytoma in the thoracic spine. This lesion showed a heterogeneous high signal intensity compared to the spinal cord on a T2-weighted image and an easily enhanced isointense signal on a T1-weighted image.

“…En su gran mayoría se presenta de forma unilateral, siendo infrecuentes los casos en que éste es bilateral 7 . Al revisar la literatura existe un caso publicado donde el paciente en cuestión se presentó con compromiso orbitario 10 y otro caso donde hubo compromiso de la fosa pterigomaxilar 11 .…”

El glomangiopericitoma es un tumor nasosinusal extremadamente raro, más frecuente en pacientes de edad avanzada y en mujeres. Si bien su etiopatogenia es desconocida, se reconocen ciertos factores predisponentes tales como hipertensión arterial, embarazo, trauma y uso de corticoides. Para su diagnóstico, resulta necesario recurrir tanto a estudio por imágenes como a la histología y técnicas de inmunohistoquímica. Microscópicamente se caracteriza por un prominente crecimiento perivascular de células uniformes ovales o fusiformes, dispuestas en fascículos cortos intercalados con capilares de diámetros variables ramificados en "asta de ciervo" y presenta inmunorreactividad positiva para actina, factor XIII-A y vimentina principalmente. Clínicamente este tumor presenta un comportamiento generalmente benigno, pero con una elevada tasa de recurrencia. Presentamos el caso de una mujer de 71 años, con antecedentes de hipertensión arterial, que acudió a nuestro centro por rinorrea purulenta y epistaxis unilateral derecha de 5 años de evolución. Al examen se observa masa polipoidea en fosa nasal derecha con abundante vascularización, sin otros hallazgos al examen físico. La lesión es resecada en su totalidad mediante cirugía endoscópica. El estudio histológico e inmunohistoquímico son compatibles con glomangiopericitoma. La paciente evoluciona con remisión de su sintomatología y a los dos meses desde la resección no ha presentado evidencias de recurrencia.

Glomangiopericytoma is a rare vascular neoplasm characterized by a pattern of prominent perivascular growth. A 72-year-old woman was admitted to our clinic complaining of nasal obstruction, frequent epistaxis, and facial pain. A reddish tumor filling the left nasal cavity was observed on endoscopy and treated with endoscopic excision. Microscopically, closely packed cells interspersed with numerous thin-walled, branching staghorn vessels were seen. Glomangiopericytoma is categorized as a borderline low malignancy tumor by WHO classification. Long-term follow-up with systemic examination is necessary due to high risk of recurrence.
