The authors present the case of a 67-year-old man with an inflammatory myofibroblastic tumor of the left ulnar nerve, which was identified intraoperatively and mimicked a malignant neoplastic lesion. Histopathological examination revealed loosely structured fibrous tissue and collagen deposits intermingled with patchy infiltrates of lymphocytes, plasma cells, and histiocytes penetrating the endo- and epineurium of the affected nerve fascicles. There was strong expression of vimentin and actin in spindle cells throughout the lesion. The histiocytes were CD68- and major histocompatibility complex class II\u2013positive, but lacked CD1a expression. A review of the literature revealed nine histopathologically confirmed cases of inflammatory myofibroblastic tumors involving peripheral or cranial nerves in which slight differences in histopathological features and surgical management were found, which are discussed here.<\/jats:p>","DOI":"10.3171\/jns.2007.106.6.1075","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T12:48:31Z","timestamp":1201178911000},"page":"1075-1079","source":"Crossref","is-referenced-by-count":2,"title":["Inflammatory myofibroblastic tumor of the ulnar nerve"],"prefix":"10.3171","volume":"106","author":[{"given":"Jens","family":"Schittenhelm","sequence":"first","affiliation":[{"name":"Institute of Brain Research,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Kaminsky","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of T\u00fcbingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Meyermann","sequence":"additional","affiliation":[{"name":"Institute of Brain Research,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Mittelbronn","sequence":"additional","affiliation":[{"name":"Institute of Brain Research,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-1061075","series-title":"Am J Surg Pathol","doi-asserted-by":"publisher","first-page":"1035","DOI":"10.1097\/00000478-199808000-00017","article-title":"Inflammatory pseudotumor of peripheral nerve","volume":"22","author":"Beer","year":"1998"},{"key":"b2-1061075","series-title":"Cancer","doi-asserted-by":"publisher","first-page":"778","DOI":"10.1002\/(SICI)1097-0142(19960215)77:4<778::AID-CNCR25>3.0.CO;2-X","article-title":"Inflammatory myofibroblastic tumor (inflammatory pseudotumor): DNA flow cytometric analysis of nine pediatric cases","volume":"77","author":"Biselli","year":"1996"},{"key":"b3-1061075","series-title":"J Neurol","doi-asserted-by":"publisher","first-page":"10","DOI":"10.1007\/BF00870665","article-title":"Amyloidoma of the gasserian ganglion as a cause of symptomatic neuralgia of the trigeminal nerve: report of three cases","volume":"241","author":"Bornemann","year":"1993"},{"key":"b4-1061075","series-title":"Adv Anat Pathol","doi-asserted-by":"publisher","first-page":"156","DOI":"10.1097\/00125480-199603030-00002","article-title":"Inflammatory pseudotumor: a family of lesions of diverse nature and etiologies","volume":"3","author":"Chan","year":"1996"},{"key":"b5-1061075","series-title":"Am J Surg Pathol","doi-asserted-by":"publisher","first-page":"761","DOI":"10.1097\/00000478-200106000-00007","article-title":"Anaplastic lymphoma kinase expression in inflammatory pseudotumors","volume":"25","author":"Chan","year":"2001"},{"key":"b6-1061075","series-title":"Cancer","doi-asserted-by":"publisher","first-page":"670","DOI":"10.1002\/1097-0142(20010801)92:3<670::AID-CNCR1369>3.0.CO;2-Q","article-title":"Treatment of unicentric and multicentric Castleman disease and the role of radiotherapy","volume":"92","author":"Chronowski","year":"2001"},{"key":"b7-1061075","series-title":"Semin Diagn Pathol","first-page":"85","article-title":"Extrapulmonary inflammatory myofibroblastic tumor: a clinical and pathological survey","volume":"15","author":"Coffin","year":"1998"},{"key":"b8-1061075","series-title":"Am J Surg Pathol","doi-asserted-by":"publisher","first-page":"859","DOI":"10.1097\/00000478-199508000-00001","article-title":"Extrapulmonary inflammatory myofibroblastic tumor (inflammatory pseudotumor).
