Abstract

Case: A 28-year-old man presented for a painful lower extremity mass. Imaging revealed a nonspecific, poorly defined lucent lesion in the left distal tibial cortex with scalloping. The diagnosis of intracortical schwannoma was made after open biopsy revealed positive S-100 immunohistochemical staining and characteristic spindled cells. Definitive management was achieved through curettage and bone grafting. Six months postoperatively, the patient's pain had improved with complete radiographic healing.

Conclusion: An intracortical schwannoma is a rare, benign lesion which may have atypical radiological findings and nonspecific presentations. Definitive diagnosis is made with permanent histology and S-100 immunohistochemical staining.

胫骨远端罕见的皮质内许旺瘤：病例报告。

病例一名 28 岁的男子因下肢肿块疼痛就诊。影像学检查发现，左侧胫骨远端皮质有一个非特异性、界限不清的透明病变，并伴有扇贝状突起。开放性活检发现 S-100 免疫组化染色阳性和特征性纺锤形细胞，诊断为皮质内分裂瘤。通过刮除术和植骨手术进行了根治。术后 6 个月，患者的疼痛有所改善，影像学检查完全愈合：皮质内分裂瘤是一种罕见的良性病变，可能有不典型的影像学表现和非特异性表现。通过永久性组织学检查和 S-100 免疫组化染色可做出明确诊断。

期刊介绍： JBJS Case Connector helps improve patient care by providing the medical community with a journal that harnesses technology to provide information tools for discovery and reporting of unusual musculoskeletal problems, findings, treatment, and outcomes. Co-edited by Thomas W. Bauer, MD, PhD, and Ronald W. Lindsey, MD, JBJS Case Connector assists orthopaedic surgeons in the search for precedents, connections, and trends in their efforts to improve patient care. Using this unique journal, surgeons can find the commonalities between cases, benefit from the experience of their peers, and filter case information by many important variables in order to provide the best possible care for orthopaedic patients. This cross-referenced online journal includes thousands of orthopaedic case reports. It compiles symptoms, conditions, and demographic details to empower surgeons to find cases similar to theirs. Surgeons can mine the database to reveal emerging trends and identify patterns, distinguishing between truly rare cases and repeated, related single instances of a larger problem. The JBJS Case Connector Image Quiz feature provides interactive quizzes based on images from content published by JBJS and includes a discussion area for further exploration of ideas and concepts. The JBJS Image Quiz app for iPad and iPhone is available in the App Store. Contributions to JBJS Case Connector are welcomed from anywhere in the world and are considered on their merits. Articles must be written in English and should be submitted as outlined in the Instructions to Authors. All authors must abide by the JBJS ethics policies and all submissions to JBJS Case Connector are covered by the JBJS embargo policy.
