The authors describe two cases of teratoid Wilms' tumor with an extrarenal site: one in a 13\u2010year\u2010old girl with vaginal spotting (patient 1) and another in a 1\u2010day\u2010old girl with a sacrococcygeal mass (patient 2). The tumors were located in the vagina and coccyx, respectively. Under the initial clinical diagnosis of sarcoma botryoides in patient 1 and teratoma in patient 2, the masses were removed. Microscopically, both tumors were composed of typical triphasic Wilms' tumor tissue with primitive cartilage and skeletal muscle, and squamous and columnar mucinous epithelia. The patient with sacrococcygeal mass (patient 2) had an elevated serum AFP level. The patients were given chemotherapy and have now remained disease free for 7\u2003years 1\u2003month, and 2\u2003years 5\u2003months after surgery, respectively. Familiarity with this rare variant of Wilms' tumor might be important in arriving at a correct diagnosis.<\/jats:p>","DOI":"10.1111\/j.1440-1827.2009.02468.x","type":"journal-article","created":{"date-parts":[[2009,11,13]],"date-time":"2009-11-13T05:32:19Z","timestamp":1258090339000},"page":"35-41","source":"Crossref","is-referenced-by-count":34,"title":["Extrarenal teratoid Wilms' tumor: Two cases in unusual locations, one associated with elevated serum AFP"],"prefix":"10.1111","volume":"60","author":[{"given":"Joon Seon","family":"Song","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In Koo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong Man","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin\u2010Kwang","family":"Khang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyu\u2010Rae","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghee","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,12,28]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19840501)53:9<1936::AID-CNCR2820530922>3.0.CO;2-W"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3468(88)80328-2"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(17)35339-9"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1080\/15513819609169311"},{"key":"e_1_2_5_6_2","first-page":"925","article-title":"Teratoid Wilms' tumor arising as a botryoid growth within a supernumerary ectopic ureteropelvic structure","volume":"122","author":"Pawel BR","year":"1998","journal-title":"Arch Pathol Lab Med"},{"key":"e_1_2_5_7_2","first-page":"242","article-title":"Teratoid Wilms' tumor: A case report","volume":"42","author":"Karaca I","year":"2000","journal-title":"Turk J Pediatr"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19930815)72:4<1422::AID-CNCR2820720443>3.0.CO;2-E"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19980115)82:2<421::AID-CNCR24>3.0.CO;2-#"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.3109\/00313028109059082"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0046-8177(89)90157-3"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004347-199807000-00014"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-002-0044-0"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1080\/00313020600820765"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.3109\/08880019809167228"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1977.3"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1989.tb02186.x"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0301-2115(98)00018-9"},{"key":"e_1_2_5_19_2","doi-asserted-by":"publisher","DOI":"10.1136\/mp.50.3.138"},{"key":"e_1_2_5_20_2","first-page":"506","article-title":"Immunohistochemical expression of Wilms' tumor 1 protein in nephroblastoma","volume":"67","author":"Chen BF","year":"2004","journal-title":"J Chin Med Assoc"},{"key":"e_1_2_5_21_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1827.2008.02323.x"},{"key":"e_1_2_5_22_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.2008.02986.x"},{"key":"e_1_2_5_23_2","unstructured":"American Cancer Society.Detailed guide: Wilms' tumor treatment by type and stage of Wilms' tumorAtlanta: American Cancer Society 2008.
