Its nonspecific clinical presentation can mimic benign conditions, leading to diagnostic delays. We report the case of a 70-year-old woman with chronic lymphoedema of the right arm following mastectomy and lymphadenectomy for breast cancer. She presented with a slowly enlarging haematoma-like lesion. Magnetic resonance imaging (MRI) performed externally suggested a benign haematoma. Due to progressive changes, the patient was referred to our department. High-resolution sonography revealed irregular dermal and subcutaneous vasculature with marked hyperperfusion. Deep skin biopsy demonstrated a vascular neoplasm composed of pleomorphic endothelial cells expressing ERG, CD31, D2-40 and c-Myc, with a high Ki-67 proliferation index, consistent with the diagnosis of cAS (Stewart\u2013Treves syndrome). Computed tomography staging excluded metastatic disease, and systemic paclitaxel therapy was initiated. This case underlines the often inconspicuous clinical presentation of cAS and the limited diagnostic value of MRI for superficial lesions. High-resolution sonography may provide an important, noninvasive diagnostic clue by revealing marked hypervascularity, thereby prompting timely biopsy and improving early detection of this aggressive tumour.<\/jats:p>","DOI":"10.1093\/skinhd\/vzaf110","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T13:19:23Z","timestamp":1764854363000},"page":"567-570","source":"Crossref","is-referenced-by-count":0,"title":["When a haematoma is not a haematoma"],"prefix":"10.1093","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2240-6736","authenticated-orcid":false,"given":"Johannes","family":"Woltsche","sequence":"first","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"Fried","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelika","family":"Kogler","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Cerroni","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Wolf","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"Salmhofer","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Medical University of Graz , Graz ,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,5,5]]},"reference":[{"key":"2026073105083522500_vzaf110-B1","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1016\/S1470-2045(10)70023-1","article-title":"Angiosarcoma","volume":"11","author":"Young","year":"2010","journal-title":"Lancet Oncol"},{"key":"2026073105083522500_vzaf110-B2","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1111\/ijd.15736","article-title":"Stewart\u2013Treves syndrome and other cutaneous malignancies in the context of chronic lymphedema: a systematic review","volume":"61","author":"Kim","year":"2022","journal-title":"Int J Dermatol"},{"key":"2026073105083522500_vzaf110-B3","doi-asserted-by":"crossref","first-page":"1342","DOI":"10.1016\/j.jaad.2012.04.028","article-title":"Stewart\u2013Treves syndrome: pathogenesis and management","volume":"67","author":"Sharma","year":"2012","journal-title":"J Am Acad Dermatol"},{"key":"2026073105083522500_vzaf110-B4","doi-asserted-by":"crossref","first-page":"e246235","DOI":"10.1001\/jamanetworkopen.2024.6235","article-title":"Incidence and presenting characteristics of angiosarcoma in the US, 2001\u20132020","volume":"7","author":"Wagner","year":"2024","journal-title":"JAMA Netw Open"},{"key":"2026073105083522500_vzaf110-B5","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1186\/s13244-021-01129-9","article-title":"Imaging features of primary sites and metastatic patterns of angiosarcoma","volume":"12","author":"Bhaludin","year":"2021","journal-title":"Insights Imaging"},{"key":"2026073105083522500_vzaf110-B6","doi-asserted-by":"crossref","first-page":"3301","DOI":"10.3390\/cancers16193301","article-title":"Ultrasound in skin cancer: why, how, and when to use it?","volume":"16","author":"Wortsman","year":"2024","journal-title":"Cancers (Basel)"}],"container-title":["Skin Health and Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/skinhd\/article-pdf\/6\/4\/567\/68221382\/vzaf110.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/skinhd\/article-pdf\/6\/4\/567\/68221382\/vzaf110.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T09:08:44Z","timestamp":1785488924000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/skinhd\/article\/6\/4\/567\/8669764"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,5]]},"references-count":6,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026,5,5]]},"published-print":{"date-parts":[[2026,7,31]]}},"URL":"https:\/\/doi.org\/10.1093\/skinhd\/vzaf110","relation":{},"ISSN":["2690-442X"],"issn-type":[{"value":"2690-442X","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,8]]},"published":{"date-parts":[[2026,5,5]]}}}
