We describe an unusual chorangioma with high cellularity and abundant mitosis that, after careful examination and postpartum follow-up, showed benign clinical course for mother and child confirming previous reported cases. This type of tumor is known in the literature as atypical cellular chorangioma and its identification is important in order to exclude potentially dangerous overtreatment.<\/jats:p>","DOI":"10.1177\/1066896915585347","type":"journal-article","created":{"date-parts":[[2015,5,20]],"date-time":"2015-05-20T23:17:08Z","timestamp":1432163828000},"page":"364-368","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Atypical Cellular Chorangioma"],"prefix":"10.1177","volume":"23","author":[{"given":"Valerio Gaetano","family":"Vellone","sequence":"first","affiliation":[{"name":"University of Genoa, Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"Calamaro","sequence":"additional","affiliation":[{"name":"University of Genoa, Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Vignale","sequence":"additional","affiliation":[{"name":"Imperia Hospital, Imperia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gianni","family":"Novaro","sequence":"additional","affiliation":[{"name":"Imperia Hospital, Imperia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucia","family":"Penna","sequence":"additional","affiliation":[{"name":"Imperia Hospital, Imperia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ezio","family":"Fulcheri","sequence":"additional","affiliation":[{"name":"University of Genoa, Genoa, Italy"},{"name":"Istituto Giannina Gaslini, Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,5,20]]},"reference":[{"key":"bibr1-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-06969-4.00015-5"},{"key":"bibr2-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1080\/713601314"},{"key":"bibr3-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1097\/00004347-198301040-00010"},{"key":"bibr4-1066896915585347","doi-asserted-by":"publisher","DOI":"10.5858\/1999-123-0536-ACC"},{"key":"bibr5-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1007\/s00292-002-0560-2"},{"key":"bibr6-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1097\/PAF.0b013e318187387e"},{"key":"bibr7-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1007\/PL00008217"},{"key":"bibr8-1066896915585347","doi-asserted-by":"publisher","DOI":"10.3109\/15513815.2010.487009"},{"key":"bibr9-1066896915585347","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-0489-8_20"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896915585347","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896915585347","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896915585347","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:20:33Z","timestamp":1777458033000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896915585347"}},"subtitle":["A Potential Diagnostic Pitfall With Worrisome Aspects but a Favorable Prognosis"],"short-title":[],"issued":{"date-parts":[[2015,5,20]]},"references-count":9,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2015,8]]}},"alternative-id":["10.1177\/1066896915585347"],"URL":"https:\/\/doi.org\/10.1177\/1066896915585347","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,5,20]]}}}
