The patient presented with a year-long history of left foot pain and a slowly enlarging, palpable mass on the plantar medial aspect of the foot. Initial evaluation and imaging revealed a well-circumscribed soft tissue mass with internal vascularity. However, due to medical history and overlapping clinical and imaging features, the differential diagnosis, among others, included rheumatoid nodules. Surgical excision of the mass was performed, and histopathology confirmed the diagnosis of traditional schwannoma. This report underlines the diagnostic challenge of distinguishing schwannomas from rheumatoid nodules and other types of soft tissue masses, specifically in patients with autoimmune disease. We discuss the clinical, radiological, and pathological aspects of this rare tumor.

Management depends on multiple factors, including fracture pattern, position, age, bone quality, and body mass index (BMI). While these injuries are often managed conservatively, outcomes vary according to individual risk factors. Operative treatment typically involves retrograde percutaneous pinning or small plate fixation. Oblique central metatarsal fractures may accommodate small-diameter screws; however, transverse fractures near the metatarsal neck remain challenging due to limited bone stock for secure hardware placement. Percutaneous Kirshner wire (K-wire) fixation offers temporary stabilization but may not adequately resist pistoning or rotational forces, particularly in distal metatarsal neck fractures. This report presents a novel technique employing extramedullary fixation to supplement intramedullary K-wire stabilization in two such cases. Both patients underwent open reduction and internal fixation using this hybrid method. At follow-up, both demonstrated complete radiographic union and a return to pre-injury activity without complications. These findings suggest that extramedullary fixation may serve as a low-profile and effective option for managing difficult distal metatarsal fractures when traditional fixation methods are limited.</div></div>","PeriodicalId":73047,"journal":{"name":"Foot & ankle surgery (New York, N.Y.)","volume":"5 4","pages":"Article 100586"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145578925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
