CONTEXT: The epidural space is a well-known, albeit uncommon, location for @entity1669 , estimated to occur in less than 3% of all @entity706 . Initial presentation of the @entity1 with disease in this site (i.e. primary @entity706 ) has been considered to be "rare". When it has been reported, many studies have emphasized the occurrence of @entity146 with a poor prognosis. DESIGN: A 10-year retrospective search of our files generated 7 @entity1 who presented @entity615 , @entity322 and/or lower extremity @entity425 , and by neuroimaging studies were found to have masses causing @entity1745 syndromes necessitating neurosurgical intervention. RESULTS: The 7 @entity1 included 4 males and 3 females with @entity1514 . Tumor types included high-grade @entity1893 , B cell type (n = 4), indolent @entity1892 (n = 1), nodular sclerosing @entity978 (n = 1) and @entity6872 (n = 1). @entity1442 (stage 4) was subsequently identified in all 7 @entity1 . Despite this, survival varied greatly with therapy, from 3 weeks to almost 6 years, underscoring the need for correct classification of the @entity706 in order to optimize chemotherapeutic choices. The epidural space was the site of presentation of disease in 4% of all @entity706 diagnosed at our institution. CONCLUSIONS: Combining all reports in the literature, epidural presentation of @entity706 is not rare. @entity706 are distinct from both primary @entity149 and from primary @entity706 . A broad range of systemic @entity5 types can present as epidural masses. A full work-up for @entity706 classification may only be possible from the tissues received at the time of the neurosurgical decompression or biopsy procedure.
