It commonly arises in the lower extremities but can present in atypical locations, complicating diagnosis.\n\nCase Report: A 77-year-old male with a 10-year history of bilateral knee pain and 6-month history of right knee swelling was examined. Physical assessment revealed bilateral knee varus deformity and a palpable, variable-consistency mass in the anteromedial aspect of the right knee. Radiographs indicated severe osteoarthritis and soft-tissue swelling. Magnetic resonance imaging showed cystic collections consistent with a ganglion cyst. Surgical excision exposed a superficial cystic mass and a deeper firm mass, confirmed histopathologically as a ganglion cyst and AFST, respectively. Immunohistochemical tests were negative for epithelial membrane antigen, S-100, and Vimentin. The patient is under regular follow-up with no recurrence in the last 12 months.\n\nConclusion: AFST should be included in the differential diagnosis of soft-tissue masses. Comprehensive diagnostic evaluations, including detailed imaging and histopathological analysis, are crucial for accurate diagnosis. Surgical excision is effective, with a favourable prognosis and low recurrence risk.\n\nKeywords: Angiofibroma, knee, ganglion cyst.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i07.7626","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:49:02Z","timestamp":1783586942000},"page":"170-175","source":"Crossref","is-referenced-by-count":0,"title":["Angiofibroma of Knee Masquerading as Ganglion Cyst \u2013 A Rare Case Report"],"prefix":"10.13107","volume":"16","author":[{"given":"Ashwini","family":"Raja","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Faculty of Medicine - Sri Lalithambigai Medical College and Hospital, Dr MGR Educational and Research Institute, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
