Because of its rare occurrence, the morphology and differentiation of pituicytoma have not been fully clarified. Here, we report a case of pituicytoma with unusual histological features mimicking ependymoma, but exhibiting the diverse morphology and differentiation of pituicytoma. The 1.4\u2003cm\u2010sized suprasellar mass was incidentally found in the magnetic resonance image of a 42\u2010year\u2010old Korean woman who had had a traffic accident. Four years later, she presented with symptoms of hypopituitarism and the follow\u2010up images revealed slight enlargement of the mass. After gross total resection, microscopic examination revealed oval to elongated cells with abundant eosinophilic cytoplasm arranged in a perivascular pseudorosette pattern and short interlacing fascicles. Pleomorphic tumor cells and Herring bodies were diffusely distributed within the tumor. Neither Rosenthal fibers nor eosinophilic granular bodies were identified. The tumor cells were immunohistochemically positive for glial fibrillary acidic protein, vimentin and S\u2010100 protein, but negative for synaptophysin and adenohypophyseal hormones. The epithelial membrane antigen and CD99 were expressed with a paranuclear dot\u2010like or membranous pattern in some tumor cells. Ultrastructural examination revealed that the tumor cells with intermediate filaments were closely apposed with intercellular junctions and frequent basal lamina production.<\/jats:p>","DOI":"10.1111\/j.1440-1827.2011.02708.x","type":"journal-article","created":{"date-parts":[[2011,8,5]],"date-time":"2011-08-05T01:51:23Z","timestamp":1312509083000},"page":"598-602","source":"Crossref","is-referenced-by-count":22,"title":["Pituicytoma with unusual histological features"],"prefix":"10.1111","volume":"61","author":[{"given":"Mi Jung","family":"Kwon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeon\u2010Lim","family":"Suh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,8,4]]},"reference":[{"key":"e_1_2_5_2_2","first-page":"1527","volume-title":"The Physiology of Reproduction","author":"Page RB","year":"1994"},{"key":"e_1_2_5_3_2","first-page":"971","volume-title":"Diagnostic Histopathology of Tumors","author":"Lopes MB","year":"2007"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00234685"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-007-0243-4"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.humpath.2008.08.013"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1958.15.5.0481"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000108983.50966.B7"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200003000-00004"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2004.07.006"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2009.09.047"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1827.2005.01890.x"},{"key":"e_1_2_5_13_2","first-page":"1653","volume-title":"Diagnostic Histopathology of Tumors","author":"Lopes MB","year":"2007"},{"key":"e_1_2_5_14_2","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1097\/00129039-200106000-00004","article-title":"CD99 immunoreactivity in ependymoma","volume":"9","author":"Choi YL","year":"2001","journal-title":"Appl Immunohistochem Mol Morphol"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02899662"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1080\/026886901750353764"},{"key":"e_1_2_5_17_2","first-page":"1813","article-title":"Pituitary ependymoma","volume":"7","author":"Sarkisian SS","year":"1956","journal-title":"U S Armed Forces Med J"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.52.12.1443"},{"key":"e_1_2_5_19_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2006.105.4.616"},{"key":"e_1_2_5_20_2","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.5858\/2009-0167-CR.1","article-title":"Pituicytoma: Characterization of a unique neoplasm by histology, immunohistochemistry, ultrastructure, and array\u2010based comparative genomic hybridization","volume":"134","author":"Phillips JJ","year":"2010","journal-title":"Arch Pathol Lab Med"},{"key":"e_1_2_5_21_2","doi-asserted-by":"publisher","DOI":"10.2176\/nmc.46.152"}],"container-title":["Pathology International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1440-1827.2011.02708.x","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1440-1827.2011.02708.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1440-1827.2011.02708.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T08:48:13Z","timestamp":1698742093000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1440-1827.2011.02708.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,8,4]]},"references-count":20,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2011,10]]}},"alternative-id":["10.1111\/j.1440-1827.2011.02708.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1440-1827.2011.02708.x","archive":["Portico"],"relation":{},"ISSN":["1320-5463","1440-1827"],"issn-type":[{"value":"1320-5463","type":"print"},{"value":"1440-1827","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,8,4]]}}}
