Deep dermal or subcutaneous involvement in EFH is very uncommon. We present three cases of nodular EFH involving the deep dermis and adipose tissue that showed characteristic cellular features and ALK immunoreactivity typical of EFH. All three cases occurred in adults and were present on the trunk or extremities. The lesions ranged from 0.8 to 2.0\u2009cm in size. Histopathologically, all cases exhibited deep dermal\/subcutaneous nodules composed of epithelioid cells with vesicular nuclei and eosinophilic cytoplasm. ALK immunohistochemistry demonstrated either cytoplasmic or cytoplasmic and nuclear labeling. Clinical follow\u2010up period ranged from 4.5 to 23\u2009years and revealed no evidence of recurrence. Our cases further expand the morphological spectrum of EFH and highlight the importance of ALK immunohistochemistry to recognize and differentiate unusual histopathological variants of EFH from its morphological mimics.<\/jats:p>","DOI":"10.1111\/cup.70071","type":"journal-article","created":{"date-parts":[[2026,2,15]],"date-time":"2026-02-15T23:17:32Z","timestamp":1771197452000},"page":"518-523","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Epithelioid Fibrous Histiocytoma Involving Deep Dermis and Subcutaneous Adipose Tissue"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1137-2107","authenticated-orcid":false,"given":"Anum","family":"Dileep","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Hartford Hospital  Hartford Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shawn E.","family":"Cowper","sequence":"additional","affiliation":[{"name":"Department of Pathology Yale School of Medicine  New Haven Connecticut USA"},{"name":"Department of Dermatology Yale School of Medicine  New Haven Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gauri","family":"Panse","sequence":"additional","affiliation":[{"name":"Department of Pathology Yale School of Medicine  New Haven Connecticut USA"},{"name":"Department of Dermatology Yale School of Medicine  New Haven Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1994.tb01290.x"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-199902000-00001"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.2015.49"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000001272"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/his.13484"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.13923"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.13068"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000001986"},{"key":"e_1_2_10_10_1","first-page":"583","article-title":"Epithelioid Cell Histiocytoma.
