We report a case of an 80\u2010year\u2010old man who presented with asymptomatic golden brown patches and diffuse pink papules on his trunk, buttocks and hips. Biopsies revealed a lichenoid infiltrate and areas of epidermotropism. Although the overall architectural pattern was compatible with mycosis fungoides, the lymphocytes had a more monocytoid and plasmacytoid appearance, and there were interspersed mature plasma cells. Immunohistological studies revealed that the pleomorphic lymphocytes were predominantly B cells (<jats:styled-content style=\"fixed-case\">CD20<\/jats:styled-content>\\+ and <jats:styled-content style=\"fixed-case\">CD79a<\/jats:styled-content>\\+) with a subpopulation of smaller bland T cells (<jats:styled-content style=\"fixed-case\">CD3<\/jats:styled-content>\\+). Moreover, the B\u2010cell immunophenotype was compatible with marginal zone differentiation (bcl\u20102+, bcl\u20106\u2212, <jats:styled-content style=\"fixed-case\">CD10<\/jats:styled-content>\u2212 and <jats:styled-content style=\"fixed-case\">CD5<\/jats:styled-content>\u2212) and showed a lambda light chain restriction, confirming monoclonality. These findings were diagnostic for cutaneous marginal zone B\u2010cell lymphoma (<jats:styled-content style=\"fixed-case\">MZL<\/jats:styled-content>) with epidermotropism an entity which has only been reported twice in the literature, once in the setting of primary cutaneous disease, and once as cutaneous involvement of systemic disease. This case illustrates a rare pattern of cutaneous <jats:styled-content style=\"fixed-case\">MZL<\/jats:styled-content>, and underscores the importance of immunophenotypic characterization of cutaneous lymphomas in order to prevent the misdiagnosis of a <jats:styled-content style=\"fixed-case\">CTCL<\/jats:styled-content>.<\/jats:p>","DOI":"10.1111\/cup.12114","type":"journal-article","created":{"date-parts":[[2013,2,21]],"date-time":"2013-02-21T23:11:15Z","timestamp":1361488275000},"page":"569-572","source":"Crossref","is-referenced-by-count":14,"title":["Epidermotropic marginal zone lymphoma simulating mycosis fungoides<sup>\u2020<\/sup>"],"prefix":"10.1111","volume":"40","author":[{"given":"Bonnie A.","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Dermatology, Montefiore Medical Center Albert Einstein College of Medicine  Bronx NY USA"},{"name":"Dermpath Diagnostics  Port Chester NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Jacobson","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Dermatology, Montefiore Medical Center Albert Einstein College of Medicine  Bronx NY USA"},{"name":"Dermpath Diagnostics  Port Chester NY USA"},{"name":"Department of Pathology, Montefiore Medical Center Albert Einstein College of Medicine  Bronx NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory","family":"Seidel","sequence":"additional","affiliation":[{"name":"Department of Pathology, Dartmouth\u2010Hitchcock Medical Center Dartmouth Medical School  Lebanon NH USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,3,27]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2004-09-3502"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2008.04.012"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-199712000-00001"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.2010.01515.x"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(99)70063-0"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2007.02522.x"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.165.20.2337"}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fcup.12114","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.12114","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T18:10:24Z","timestamp":1700676624000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cup.12114"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,3,27]]},"references-count":7,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2013,6]]}},"alternative-id":["10.1111\/cup.12114"],"URL":"https:\/\/doi.org\/10.1111\/cup.12114","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"value":"0303-6987","type":"print"},{"value":"1600-0560","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,3,27]]}}}
