It usually arises from head, neck, and trunk. Retroperitoneal schwannoma is a rare entity, accounting for only 0.3\u20133% of total schwannomas. Majority of retroperitoneal schwannomas reported in literature have a diameter of 5 to 15\u2009cm. Preoperative diagnosis is difficult due to low frequency, nonspecific clinical course, and nonspecific imaging features. Histology usually provides definitive diagnosis. Schwannomas are solitary, well-circumscribed, and noninvasive, so complete surgical excision provides good result. We report a case of a 23-year-old male, who presented with progressive abdominal distension and intermittent episodes of intestinal obstruction. CECT was suggestive of huge solid-cystic mass in abdominopelvic region. Image guided percutaneous aspiration revealed around 1 litre of frank pus and FNAC was suggestive of abscess. Exploratory laparotomy revealed a large 32 \u00d7 28 \u00d7 26\u2009cm mass with solid and cystic components containing 1 litre of pus. Histological features of tumour were suggestive of benign schwannoma and immunohistochemistry for S-100 was positive. Postoperative recovery was uneventful. We report this case of a retroperitoneal schwannoma because of giant size, rare location, unusual presentation, and diagnostic dilemma.<\/jats:p>","DOI":"10.1155\/2014\/628538","type":"journal-article","created":{"date-parts":[[2014,8,27]],"date-time":"2014-08-27T17:03:28Z","timestamp":1409159008000},"page":"1-4","source":"Crossref","is-referenced-by-count":4,"title":["Diagnostic Dilemma of a Rare, Giant Retroperitoneal Schwannoma: A Case Report and Review of Literature"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8769-8269","authenticated-orcid":true,"given":"Mahendra","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Surgery, AIIMS, Basni, Jodhpur, Rajasthan 342001, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lovekesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hindu Rao Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajkumar","family":"Chejara","sequence":"additional","affiliation":[{"name":"Department of Surgery, VMMC & SJ Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Om Prakash","family":"Prasad","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hindu Rao Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuvraj","family":"Kolhe","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hindu Rao Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0916-0281","authenticated-orcid":true,"given":"Ashish","family":"Saxena","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hindu Rao Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-7-12"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1445-2197.2007.04025.x"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-196305000-00006"},{"issue":"1","key":"4","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1177\/230949900201000114","volume":"10","year":"2002","journal-title":"Journal of Orthopaedic Surgery"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/781347"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-8-66"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2005.01.016"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1080\/02841859909174408"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1986.tb48070.x"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1046\/j.1442-2042.2003.00702.x"}],"container-title":["Case Reports in Oncological Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crionm\/2014\/628538.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crionm\/2014\/628538.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crionm\/2014\/628538.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T15:28:55Z","timestamp":1498145335000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crionm\/2014\/628538\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":10,"alternative-id":["628538","628538"],"URL":"https:\/\/doi.org\/10.1155\/2014\/628538","relation":{},"ISSN":["2090-6706","2090-6714"],"issn-type":[{"type":"print","value":"2090-6706"},{"type":"electronic","value":"2090-6714"}],"subject":[],"published":{"date-parts":[[2014]]}}}
