Historically, terms such as \u2018cavernous hemangioma\u2019 have been used imprecisely. Recent consensus supports classifying these lesions as vascular malformations rather than tumors. We report a case of a 58-year-old man with a venous malformation of the arm that became clinically evident at the site of venous blood sampling 10\u00a0years earlier. Preoperative computed tomography scan showed a well-circumscribed, vascularized mass in the antecubital fossa. Excision was performed for progressive enlargement, recurrent thrombophlebitis. Histopathology confirmed a low-flow venous malformation consistent with current vascular anomaly classifications. Although venous malformations are congenital lesions, the temporal association with venous puncture suggests that local trauma may have induced hemorrhage or thrombosis, acting as a trigger for lesion enlargement and clinical manifestation. This case highlights the possible role of local trauma in triggering the clinical manifestation and progression of a previously silent venous malformation.<\/jats:p>","DOI":"10.1093\/jscr\/rjag912","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T11:33:30Z","timestamp":1791286410000},"source":"Crossref","is-referenced-by-count":0,"title":["Needle trauma as a trigger for clinical manifestation of a pre-existing venous malformation: a case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Luca","family":"Dainese","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Centro Cardiologico Monzino IRCCS , Via Parea 4, 20138 Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Saccu","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Centro Cardiologico Monzino IRCCS , Via Parea 4, 20138 Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Zoli","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Centro Cardiologico Monzino IRCCS , Via Parea 4, 20138 Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Nava","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Centro Cardiologico Monzino IRCCS , Via Parea 4, 20138 Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5409-0791","authenticated-orcid":false,"given":"Alice","family":"Bonomi","sequence":"additional","affiliation":[{"name":"Biostatistics Unit, Centro Cardiologico Monzino IRCCS , Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedetta","family":"Di Venosa","sequence":"additional","affiliation":[{"name":"Division of Pathology and Laboratory Medicine, IEO, European Institute of Oncology IRCCS , Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piero","family":"Trabattoni","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Centro Cardiologico Monzino IRCCS , Via Parea 4, 20138 Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,10,14]]},"reference":[{"key":"2026101422020096900_ref1","doi-asserted-by":"publisher","first-page":"314","DOI":"10.1016\/j.jvs.2018.12.033","article-title":"Vascular anomalies.
