Involvement of the extremities, particularly the digits and underlying bone, is extremely rare, especially in young age, often leading to diagnostic delays and therapeutic uncertainty. A 18\u2010year\u2010old female presented with a progressively enlarging, painless mass on the dorsum of the left ring finger. Clinical examination revealed a firm, non\u2010tender, subcutaneous lesion with no signs of systemic illness. Radiographic imaging demonstrated a lytic lesion with cortical erosion involving the middle phalanx. The mass was surgically excised under local anesthesia without preoperative antibiotic therapy. Histopathological examination confirmed actinomycosis, revealing filamentous bacterial colonies (sulfur granules) within a suppurative and fibrotic background. This case underscores the importance of including actinomycosis in the differential diagnosis of chronic digital swellings, particularly in atypical anatomical sites. Surgical excision remains a valuable diagnostic and therapeutic approach in such rare presentations.<\/jats:p>","DOI":"10.1002\/ccr3.71860","type":"journal-article","created":{"date-parts":[[2026,1,16]],"date-time":"2026-01-16T03:47:13Z","timestamp":1768535233000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ring Finger Mass: A Rare Case of Digital Actinomycosis Surgically Removed From a Young Patient"],"prefix":"10.1002","volume":"14","author":[{"given":"Abdulkarim","family":"Hasan","sequence":"first","affiliation":[{"name":"Pathology and Laboratory Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"},{"name":"Pathology Department, Faculty of Medicine Al\u2010Azhar University  Cairo Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Nagi","sequence":"additional","affiliation":[{"name":"Surgery Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hussein","family":"Eldamery","sequence":"additional","affiliation":[{"name":"Orthopaedic Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Assem","family":"Amer","sequence":"additional","affiliation":[{"name":"Orthopaedic Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Mabrouk","sequence":"additional","affiliation":[{"name":"Rheumatology Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashraf Yahia","family":"Hegab","sequence":"additional","affiliation":[{"name":"Internal Medicine Department Prince Mishari bin Saud Hospital in Baljurashi, Al\u2010Baha Health Cluster, Ministry of Health  Al\u2010Baha Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed E.
