Cutaneous mesenchymal neoplasms composed predominantly or exclusively of epithelioid cells are relatively uncommon and can cause considerable diagnostic difficulties due to overlapping histologic features among heterogeneous groups of tumors. Familiarity with practical diagnostic approaches and recognition of key histopathologic features are important for correct diagnosis and management. This review summarizes the histologic features of epithelioid cutaneous mesenchymal neoplasms and discusses their differential diagnoses from malignant melanomas and carcinomas.<\/jats:p>","DOI":"10.3390\/diagnostics10040233","type":"journal-article","created":{"date-parts":[[2020,4,21]],"date-time":"2020-04-21T03:23:06Z","timestamp":1587439386000},"page":"233","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Epithelioid Cutaneous Mesenchymal Neoplasms: A Practical Diagnostic Approach"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8638-0360","authenticated-orcid":false,"given":"Joon Hyuk","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Pathology, Yeungnam University College of Medicine, Daegu 42415, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Y.","family":"Ro","sequence":"additional","affiliation":[{"name":"Department of Pathology and Genomic Medicine, Houston Methodist Hospital, Weill Medical College of Cornell University, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,17]]},"reference":[{"key":"ref_1","unstructured":"Hornick, J.L.
