The lesion is generally intraosseous with vague clinical symptoms, hence given the name\n                    <jats:italic>great mimicker<\/jats:italic>\n                    . When located subperiosteally and juxta-articulary, atypical clinical presentation and radiographs may lead to a delayed or missed diagnosis. Performing surgery with a misdiagnosis carries the risk of incomplete resection of the lesion and recurrence. We report the case of a 15-year-old male with a subperiosteal osteoid osteoma of the talus, who was misdiagnosed with pigmented villonodular synovitis (PVNS) and operated through anterior ankle arthrotomy. A nodular lesion, 1 cm in diameter, with a hard rubber consistency, was removed from the dorsal aspect of the talar neck. The pathologic specimens were consistent with subperiosteal osteoid osteoma. The patient\u2019s symptoms resolved rapidly in the early postoperative period. The patient remained asymptomatic at the 20-month follow-up and the control magnetic resonance imaging revealed no signs of recurrence. Atypical radiographs and clinical presentation of juxta-articular subperiosteal osteoid osteomas cause misdiagnosis, delay in diagnosis, incomplete resection, and recurrence. It is important to keep in mind \u201cjuxta-articular subperiosteal osteoid osteoma\u201d in the differential diagnosis of cases with suspected pigmented villonodular synovitis.\n                  <\/jats:p>","DOI":"10.7547\/23-006","type":"journal-article","created":{"date-parts":[[2024,4,4]],"date-time":"2024-04-04T10:38:31Z","timestamp":1712227111000},"source":"Crossref","is-referenced-by-count":0,"title":["Osteoid Osteoma of the Talus Mimicking Pigmented Villonodular Synovitis in a 15-Year-Old Male"],"prefix":"10.3390","volume":"115","author":[{"given":"O\u011fuzhan","family":"G\u00f6kalp","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, U\u015fak University, Faculty of Medicine, U\u015fak, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cenk","family":"Ermutlu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Uluda\u011f University, Faculty of Medicine, Bursa, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet Bartu","family":"Sar\u0131s\u00f6zen","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Uluda\u011f University, Faculty of Medicine, Bursa, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kemal","family":"Durak","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Uluda\u011f University, Faculty of Medicine, Bursa, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulviye","family":"Yal\u00e7\u0131nkaya","sequence":"additional","affiliation":[{"name":"Department of Medical Pathology, Uluda\u011f University, Faculty of Medicine, Bursa, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adnan","family":"\u00c7akar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Uluda\u011f University, Faculty of Medicine, Bursa, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","reference":[{"key":"B1","series-title":"Arch Surg","first-page":"709","article-title":"\u201cOsteoid-Osteoma\u201d: a benign osteoblastic tumor composed of osteoid and atypical bone","volume":"31","author":"Jaffe H","year":"1935","unstructured":"Jaffe H. \u201cOsteoid-Osteoma\u201d: a benign osteoblastic tumor composed of osteoid and atypical bone.
