A skin biopsy suggested lipoma, leading to observation. Over the next 5\u2009years, the tumor gradually enlarged. Clinical evaluation found the tumor to be a soft, mobile mass of 10\u2009\u00d7\u20097\u2009cm. Magnetic resonance imaging showed the lesion to be cystic, with hyperintense mural nodules on T2\u2010weighted sequences, and with scattered, hyperintense foci indicative of fatty components on T1\u2010weighted imaging. Fat\u2010suppressed contrast\u2010enhanced T1\u2010weighted imaging revealed moderately enhanced mural nodules. Surgical resection revealed a well\u2010circumscribed cystic mass containing fluid, surrounded by a fibrous capsule. We suspected spindle cell lipoma associated with fluid and performed a marginal resection. Gross examination showed a heterogeneous mixture of reddish\u2010brown and yellowish zones interspersed with fissures. Histological analysis revealed a leaf\u2010like or reticular pattern, with slender, spindle\u2010shaped cells and ropey collagens within a mucinous matrix, along with mature adipocytes. There were many irregular, branching, cleft\u2010like vascular spaces lined by flattened cells. Immunohistochemical staining revealed tumor cells positive for CD34 and negative for retinoblastoma protein. Luminal endothelial\u2010like cells showed positivity for D2\u201040, CD31, and erythroblastosis transformation\u2010specific regulated gene 1. Based on these findings, the diagnosis of pseudoangiomatous spindle\u2010cell lipoma was confirmed, with the luminal endothelial\u2010like cells exhibiting characteristics of lymphatic endothelium.<\/jats:p>","DOI":"10.1111\/1346-8138.17701","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T08:05:22Z","timestamp":1742198722000},"page":"943-946","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A case of pseudoangiomatous spindle\u2010cell lipoma with unique\n                    <scp>MRI<\/scp>\n                    manifestations corresponding to distinct histological features"],"prefix":"10.1111","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7511-4477","authenticated-orcid":false,"given":"Maho","family":"Matsuo","sequence":"first","affiliation":[{"name":"Department of Dermatology Gifu University Graduate School of Medicine  Gifu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Kato","sequence":"additional","affiliation":[{"name":"Department of Radiology Gifu University Graduate School of Medicine  Gifu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Pathology Gifu University Graduate School of Medicine  Gifu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miki","family":"Nagai","sequence":"additional","affiliation":[{"name":"Department of Dermatology Gifu Prefectural General Medical Center  Gifu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8781-2735","authenticated-orcid":false,"given":"Hiroaki","family":"Iwata","sequence":"additional","affiliation":[{"name":"Department of Dermatology Gifu University Graduate School of Medicine  Gifu Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,3,17]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"2613","article-title":"Spindle cell lipoma: clinicopathologic characterization of 40 cases","volume":"12","author":"Chen S","year":"2019","journal-title":"Int J Clin Exp Pathol"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.20220743"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.annpat.2011.04.003"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/aqw137"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31825d532d"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/pin.12497"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1994.tb00577.x"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1673.1997.tb00726.x"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1827.2007.02052.x"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00428-005-0007-2"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.29271\/jcpsp.2018.05.352"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1096\/fj.01-1010fje"}],"container-title":["The Journal of Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.17701","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/1346-8138.17701","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.17701","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T17:39:11Z","timestamp":1772991551000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1346-8138.17701"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3,17]]},"references-count":12,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2025,5]]}},"alternative-id":["10.1111\/1346-8138.17701"],"URL":"https:\/\/doi.org\/10.1111\/1346-8138.17701","archive":["Portico"],"relation":{},"ISSN":["0385-2407","1346-8138"],"issn-type":[{"value":"0385-2407","type":"print"},{"value":"1346-8138","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,3,17]]},"assertion":[{"value":"2024-11-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-03-03","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-03-17","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
