Multiplicity is also a common finding. Histopathologically, EH is characterized by a mixture of vascular proliferation and marked mixed inflammatory cell infiltration, and was first de scribed by Wells and Whimster 2 as angiolymphoid hyperplasia with eosinophilia. The proliferation of vascular structures lined with prominent endothelial cells is a distinguishing feature of EH. The epithelioid endothelial cells that protrude into the vascular lumen create a characteristic “cobble-stone” or “tombstone” appearance. A chronic inflammatory cell infiltration in cluding lymphoplasma cells and eosinophils is a consistent find ing. EH has a diverse range of microscopic features, depending on the composition and distribution of the vascular and inflam matory cellular components. EH has been described in the literature as an inflammatory angiomatous nodule or, an atypical or pseudopyogenic granuloma, 3,4 when infiltration of various inflammatory cells is predominant, and a histiocytoid hemangi oma 5 when cobble stone-like endothelial cells are conspicuous. Some cases of EH consist entirely of solid sheets of epithelioid to spindled cells without fully canalized vascular structures. The solid form of EH can be difficult to diagnose and is occa sionally misdiagnosed as a malignant vascular tumor. EH is a benign neoplasm and surgical excision is sufficient for its treat ment. Recently, we experienced a solid form of EH with no inflammatory component, which showed a dramatic change into the typical morphology on the consecutive biopsy. This is the first reported Korean case of a solid form of EH, which patholo gists should include in the differential diagnosis of epithelioid vascular lesions to avoid overdiagnosis of epithelioid vascular malignancies.","PeriodicalId":49936,"journal":{"name":"Korean Journal of Pathology","volume":"48 5","pages":"394-7"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4132/KoreanJPathol.2014.48.5.394","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32788831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
