Due to the rarity of its presentation, particularly with multiple lymph node metastasis resembling lymphoproliferative disorders, emphasizes the need to share our case in the literature. We aimed to raise awareness among surgeons regarding this atypical presentation. Our findings indicate that, in cases of higher stage thymic carcinoma, lymph node dissection should be considered in addition to thymectomy. This recommendation is based on our research and can help guide treatment decisions for similar cases in the future.","PeriodicalId":506938,"journal":{"name":"Journal of Microscopy and Ultrastructure","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139619786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a rare type of vascular tumor that primarily affects men in their middle ages. Typically, it appears as a single or few reddish-to-brown nodules. EHs of the oral cavity have only seldom been reported up to this point. Histologically, it is distinguished by lobular vessel configuration, tombstone-like epithelioid cells lining the vessel wall, and a persistent inflammatory infiltration predominately made up of eosinophils. Although the terms EH and epithelioid hemangioendothelioma are sometimes confused, the two are distinct based on histopathology and a number of immunohistochemistry (IHC) markers, including high Ki67 index and ERG positivity observed later. Local trauma to a nearby vessel may be one of the etiopathogeneses for this entity. This is a rare case report of EH that was identified with the use of a panel of IHC markers and hematoxylin and eosin histology.","PeriodicalId":506938,"journal":{"name":"Journal of Microscopy and Ultrastructure","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139618233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
