Although thought to be closely related to mature T helper cells, the relation between the neoplastic cells in MF and SS is still not fully clarified. This report describes a patient with complete remission of SS under treatment with extracorporeal photophoresis (ECP), who subsequently developed typical plaques of MF and large cell lymphoma (LCL). Serial polymerase chain reaction analyses confirmed identical T cell receptor \u03b2 and \u03b3 gene rearrangements in SS, MF, and LCL, and complete disappearance of the circulating malignant T cell clone from the peripheral blood after ECP. These findings indicate that the neoplastic cells in SS, MF, and LCL are derived from a common precursor T cell, despite the change in clinical phenotype.<\/jats:p>","DOI":"10.1136\/jcp.2004.017160","type":"journal-article","created":{"date-parts":[[2004,11,24]],"date-time":"2004-11-24T13:12:48Z","timestamp":1101301968000},"page":"1325-1328","source":"Crossref","is-referenced-by-count":8,"title":["Transition of S\u00e9zary syndrome into mycosis fungoides after complete clinical and molecular remission under extracorporeal photophoresis"],"prefix":"10.1136","volume":"57","author":[{"given":"C","family":"Assaf","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Hummel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Zemlin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Steinhoff","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C C","family":"Geilen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Stein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C E","family":"Orfanos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2004,11,24]]},"reference":[{"key":"2025092505510517000_57.12.1325.1","doi-asserted-by":"crossref","first-page":"2908","DOI":"10.1200\/JCO.2000.18.15.2908","volume":"18","year":"2000","journal-title":"J Clin Oncol"},{"key":"2025092505510517000_57.12.1325.2","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.139.7.857"},{"key":"2025092505510517000_57.12.1325.3","first-page":"276","volume":"26","year":"1999","journal-title":"Semin Oncol"},{"key":"2025092505510517000_57.12.1325.4","doi-asserted-by":"publisher","DOI":"10.1111\/1523-1747.ep12388985"},{"key":"2025092505510517000_57.12.1325.5","doi-asserted-by":"publisher","DOI":"10.1097\/00019606-199806000-00003"},{"key":"2025092505510517000_57.12.1325.6","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1182\/blood.V96.2.640.014k31_640_646","volume":"96","year":"2000","journal-title":"Blood"},{"key":"2025092505510517000_57.12.1325.7","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-9896(199906)188:2<146::AID-PATH334>3.0.CO;2-7"},{"key":"2025092505510517000_57.12.1325.8","unstructured":"In: Jaffe ES, Harris NL, Stein H, Vardiman JW, eds.
