Non-specific symptoms and a varied histological appearance often lead to misdiagnosis, delayed treatment and prolonged morbidity for the patient. We report a case of a patient in his late forties presenting with generalised body ache, weakness and difficulty in walking for 3 years. Biochemical investigations revealed an increased renal phosphate wasting, with functional imaging showing a somatostatin receptor-expressing lesion in the distal epiphysis of the left tibia. A CT scan was done to precisely locate the tumour which was then resected en bloc. The patient was managed postoperatively with oral phosphate and vitamin D supplementation, which saw him recover completely at 1-year follow-up. Guidelines for diagnosis and treatment of PMTs need to be established to streamline the management of this condition.<\/jats:p>","DOI":"10.1136\/bcr-2025-265869","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T16:15:20Z","timestamp":1777479320000},"page":"e265869","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Tumour-induced osteomalacia: a diagnostic conundrum"],"prefix":"10.1136","volume":"19","author":[{"given":"Jasjeet","family":"Singh","sequence":"first","affiliation":[{"name":"Orthopedics, St John\u2019s Medical College Hospital, Bangalore, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monish","family":"Nachu","sequence":"additional","affiliation":[{"name":"Orthopedics, St John\u2019s Medical College Hospital, Bangalore, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajagopal","family":"Honnasandra Prabhakar","sequence":"additional","affiliation":[{"name":"Orthopedics, St John\u2019s Medical College Hospital, Bangalore, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"2026042909150867000_19.4.e265869.1","first-page":"33","article-title":"Osteomalacia with Looser\u2019s nodes (Milkman\u2019s syndrome) due to a raised resistance to vitamin D acquired about the age of 15 years","volume":"16","author":"McCANCE","year":"1947","journal-title":"Q J Med"},{"key":"2026042909150867000_19.4.e265869.2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19870415)59:8<1442::AID-CNCR2820590810>3.0.CO;2-Q"},{"key":"2026042909150867000_19.4.e265869.3","unstructured":"Bosman FT , Jaffe ES , Lakhani SR , et al .
