Giant neurilemmomas derived from the retroperitoneum have rarely been reported. We herein describe a woman with a giant retroperitoneal neurilemmoma that was initially incorrectly diagnosed as an inflammatory abdominal mass. The tumor extended from the patient\u2019s hypogastrium to her pelvic cavity and measured 20\u2009\u00d7\u200915\u2009\u00d7\u200910\u2009cm. The tumor was excised via laparotomy and diagnosed as a retroperitoneal neurilemmoma through histological and immunohistochemical examination. Although rare, particularly in the giant form, neurilemmoma should be considered as an important differential diagnosis in patients with a retroperitoneal tumor or inflammatory abdominal mass. Complete excision should be considered for the potential cure of giant retroperitoneal neurilemmomas.<\/jats:p>","DOI":"10.1177\/0300060520935302","type":"journal-article","created":{"date-parts":[[2020,9,14]],"date-time":"2020-09-14T06:09:32Z","timestamp":1600063772000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["A
