The aim of this single-centre retrospective study was to identify factors that can be used to improve the diagnosis of erythroderma. Among 91 patients with erythroderma, 21 were diagnosed with eczema, 17 with psoriasis, 20 with drug-induced erythroderma, 13 with erythrodermic mycosis fungoides and 20 with S\u00e9zary syndrome. Nail alterations, ear involvement, and severe scaling were significantly associated with psoriasis (p\u2009=\u20090.044). Fever and hypereosinophilia were associated with drug-induced erythroderma. Expression of programmed cell death protein 1 was observed in all skin biopsies. However, with S\u00e9zary syndrome, programmed cell death protein 1 expression was significantly higher than with other aetiologies. A programmed cell death protein 1 hormone receptor score (H-score) &gt;50 was associated with S\u00e9zary syndrome (p\u2009&lt;\u20090.001, sensitivity 75%, specificity 92%) as well as CXCL13 expression (p\u2009&lt;\u20090.044). CD7 loss was more frequent with erythrodermic mycosis fungoides and S\u00e9zary syndrome (p\u2009=\u20090.022). This study reports the importance of programmed cell death protein 1 expression for the differential diagnosis of S\u00e9zary syndrome and other aetiologies, including erythrodermic mycosis fungoides.<\/jats:p>","DOI":"10.2340\/actadv.v102.1062","type":"journal-article","created":{"date-parts":[[2022,6,27]],"date-time":"2022-06-27T11:38:55Z","timestamp":1656329935000},"page":"adv00773","source":"Crossref","is-referenced-by-count":6,"title":["A High Programmed Cell Death Protein 1 Hormone Receptor Score on Skin Biopsy is Associated with S\u00e9zary Syndrome Diagnosis: A Study of 91 Patients with Erythroderma"],"prefix":"10.2340","volume":"102","author":[{"given":"Camille","family":"Luherne","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Menguy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Ferte","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie","family":"Beylot-Barry","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien","family":"Seneschal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brigitte","family":"Milpied","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Philippe","family":"Vial","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey","family":"Gros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Amintas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00e9atrice","family":"Vergier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Pham-Ledard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2022,9,6]]},"reference":[{"key":"21437","doi-asserted-by":"crossref","unstructured":"Botella-Estrada R.
