title: Primary spinal epidural B-lymphoblastic lymphoma.
abstract: Extranodal lymphomas constitute 20% to 30% of all non-Hodgkin's lymphomas. The common sites involved are skin, stomach, brain, and small intestine. Epidural localization is a rare site for lymphomas, accounting for 10% of spinal epidural tumors. Lymphomas occurring primarily in the epidural space without other previously detected lymphomatous foci (i.e., primary spinal epidural lymphomas) represent an even rarer entity. We report a case of primary spinal epidural B-lymphoblastic lymphoma. The patient presented with paraparesis, and a spinal epidural lesion was diagnosed. Considering the rapidity of symptom onset, the possibility of epidural abscess was considered, and he underwent partial laminectomy with decompression of the lesion. Histopathology and immunohistochemistry were diagnostic of B-lymphoblastic lymphoma. The present case is the first report in the literature of B-lymphoblastic lymphoma presenting as a spinal epidural lesion.
