CD30+ clonal T-cell lymphoid proliferation of the skin in a patient with hypereosinophilic syndrome


Kempf, Werner; Kazakov, Dmitry V; Szep, Zoltan; Vanecek, Tomas (2015). CD30+ clonal T-cell lymphoid proliferation of the skin in a patient with hypereosinophilic syndrome. Journal of Cutaneous Pathology, 42(2):130-135.

Abstract

We report a hitherto undescribed unusual CD30+ clonal T-cell proliferation in a 46-year-old man with the lymphocytic variant of hypereosinophilic syndrome with a 17-year history of pruritus, generalized persistent papulonodular skin lesions and peripheral blood hypereosinophilia. A skin biopsy showed an eosinophil-rich infiltrate with small to medium-sized CD30+ lymphocytes and Churg-Strauss granulomas. Peripheral blood flow cytometry revealed an aberrant T-cell clone which, molecular genetically, was identical to the T-cell clone detected in the skin. No genetic aberrations of platelet-derived growth factor receptor alpha (PDGFRA), FIP1L1-PDGFRA, PDGFRB or FGFR1 were found. The skin lesions showed transient response to systemic and topical corticosteroids. The skin lesions represent cutaneous involvement by clonal T-cells in hypereosinophilic syndrome and differ from known cutaneous CD30+ lymphoproliferative disorders.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
