The neoplasm first presented with paraneoplastic osteomalacia causing a pathological femur fracture. A right maxillary sinus tumour was identified and treated thereafter. The patient had no local symptoms and serum electrolytes returned to normal after surgical removal of the tumour. However, 10\u2005years later, the patient's urine Ca and P levels increased and an octreoscan detected a new tumour in the right maxillary sinus. Early diagnosis prevented the effects of the paraneoplastic activity of the neoplasm. This case emphasises the importance of specific, close follow-up, because the neoplasm rarely produces local signs indicating its position. To our knowledge, this is the first reported case of a late relapse presenting without relevant symptoms (local pain or swelling or pathological fractures).<\/jats:p>","DOI":"10.1136\/bcr-2013-202827","type":"journal-article","created":{"date-parts":[[2014,5,14]],"date-time":"2014-05-14T14:49:45Z","timestamp":1400078985000},"page":"bcr2013202827","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Mesenchymal phosphaturic tumour: early detection of recurrence"],"prefix":"10.1136","volume":"2014","author":[{"given":"Fabiana","family":"Allevi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitri","family":"Rabbiosi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Mandal\u00e0","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giacomo","family":"Colletti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,5,14]]},"reference":[{"key":"2025042703383302000_2014.may14_1.bcr2013202827.1","first-page":"554","article-title":"Rachitis infolge, knochen tumors","volume":"14","author":"Prader","year":"1959","journal-title":"Helv Pediatr Acta"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2010.04.039"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.3","first-page":"3","article-title":"Phosphaturic mesenchymal tumor of the sinonasal area: case report and review of the literature","volume":"16","author":"Kominek","year":"2011","journal-title":"Head Neck Oncol"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.4","doi-asserted-by":"publisher","DOI":"10.1007\/s002560000306"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2008.01.003"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.6","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2265.2001.01056.x"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.7","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2004-0406"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.8","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197804)41:4<1414::AID-CNCR2820410429>3.0.CO;2-O"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.9","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200002000-00011"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.10","doi-asserted-by":"publisher","DOI":"10.1007\/s002560050581"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.11","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19870415)59:8<1442::AID-CNCR2820590810>3.0.CO;2-Q"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.12","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200401000-00001"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.13","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa010839"},{"key":"2025042703383302000_2014.may14_1.bcr2013202827.14","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200205303462215"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-202827","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T10:38:46Z","timestamp":1745750326000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-202827"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,5,14]]},"references-count":14,"alternative-id":["10.1136\/bcr-2013-202827"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-202827","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2014,5,14]]}}}
