ABSTRACT
Hemangiopericytoma and fibrosarcoma represented at one time two of the most common diagnoses in soft tissue pathology. Both terms are now largely extinct. This article will review the clinicopathologic, immunohistochemical and molecular genetic advances that have led to these changes, and review the pathologic features of a select group of soft tissue tumors previously classified as hemangiopericytoma or fibrosarcoma.

El hemangiopericitoma es un raro tumor que puede compromeeter a la columna espinal, siendo la localización intradural extremadamente infrecuente. Se presenta un caso de un paciente de sexo masculino, de 54 años de edad, que consulta por lumbocitalgia de meses de evolución, con diagnóstico de hemangiopericitoma intradural de la columna lumbar. Se describen los hallazgos obtenidos en la RM y en la anatomía patológica (AU)
