Fibro-osseous pseudotumor of the digit typically affects young to middle-aged adults (mean age, 36 years) with a slight female predominance. Lesions presented as rapidly enlarging painful nodules, occasionally associated with prior trauma, and were frequently mistaken for infection or extraskeletal osteosarcoma. Complete surgical excision was the definitive treatment, with recurrence reported rarely and almost exclusively following incomplete excision. Our case demonstrated recurrence after initial debridement, with subsequent definitive excision leading to functional recovery, although residual stiffness and sensory disturbance persisted.</p><p><strong>Conclusions: </strong>Fibro-osseous pseudotumor of the digit should be considered in the differential diagnosis of rapidly enlarging digital lesions. Complete surgical excision is curative in most cases, while molecular markers such as ubiquitin-specific peptidase 6 may refine the diagnosis in morphologically ambiguous presentations. Future research should prioritise the development of standardised diagnostic criteria, prognostic markers, and long-term outcome reporting.</p>","PeriodicalId":12902,"journal":{"name":"HAND","volume":" ","pages":"15589447261481209"},"PeriodicalIF":1.3,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148891007","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}
