Among them, patients with gamma-HCD are so rare that no more than 150 cases can be found in the literature. In this paper, we report one additional case: an 83-year-old man with a gamma-HCD, in whom a kappa light chain component was detected in the serum by using the serum free light-chain assessment and in addition monoclonal kappa cytoplasmic expression was detected in bone marrow plasma cells by flow cytometric analysis. In the work-up of the patient, the underlying anatomopathological lymphoproliferative disease corresponded to a lymphoplasmacytic lymphoma, as it is stated in the current World Health Organization classification (2008), with both lymphadenopathic and bone marrow infiltration. As in other cases, several autoimmune manifestations (antiphospholipidic syndrome and immune thrombocytopenia) were present during the course of the disease in this patient. This case report illustrates a new case of gamma-HCD, in which serum free light-chain analysis and flow cytometry represented a valuable tool for diagnosis, a finding that could be very important for the future management of these patients.<\/jats:p>","DOI":"10.1258\/acb.2010.010146","type":"journal-article","created":{"date-parts":[[2010,10,7]],"date-time":"2010-10-07T21:05:03Z","timestamp":1286485503000},"page":"570-572","source":"Crossref","is-referenced-by-count":7,"title":["Monoclonal free light chains can be found in heavy chain diseases"],"prefix":"10.1177","volume":"47","author":[{"given":"L","family":"L\u00f3pez-Anglada","sequence":"first","affiliation":[{"name":"Haematology Department"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N","family":"Puig","sequence":"additional","affiliation":[{"name":"Haematology Department"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"D\u00edez-Campelo","sequence":"additional","affiliation":[{"name":"Haematology Department"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Alonso-Ralero","sequence":"additional","affiliation":[{"name":"Clinical Analysis Department"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Barrena","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n del C\u00e1ncer (CIC)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M A","family":"Aparicio","sequence":"additional","affiliation":[{"name":"Anatomical Pathology Department, University Hospital of Salamanca, Salamanca, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N C","family":"Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Haematology Department"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Garc\u00eda-Sanz","sequence":"additional","affiliation":[{"name":"Haematology Department"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,10,7]]},"reference":[{"key":"bibr-ACB-10-146C1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(64)90191-3"},{"key":"bibr-ACB-10-146C2","doi-asserted-by":"publisher","DOI":"10.1016\/j.beha.2005.01.029"},{"key":"bibr-ACB-10-146C3","first-page":"89","volume":"19","author":"Hauke G","year":"1991","journal-title":"Immun Infekt"},{"key":"bibr-ACB-10-146C4","doi-asserted-by":"publisher","DOI":"10.1097\/01.md.0000085058.63483.7f"},{"key":"bibr-ACB-10-146C5","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2008.307"},{"key":"bibr-ACB-10-146C6","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.11080"},{"key":"bibr-ACB-10-146C7","doi-asserted-by":"publisher","DOI":"10.1038\/sj.leu.2403202"},{"key":"bibr-ACB-10-146C8","doi-asserted-by":"publisher","DOI":"10.1172\/JCI113722"},{"key":"bibr-ACB-10-146C9","first-page":"489","volume":"32","author":"Buxbaum JN","year":"1978","journal-title":"Clin Exp Immunol"},{"key":"bibr-ACB-10-146C10","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-198911000-00001"},{"key":"bibr-ACB-10-146C11","doi-asserted-by":"publisher","DOI":"10.1053\/sonc.2003.50074"},{"key":"bibr-ACB-10-146C12","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2007.15.4120"},{"key":"bibr-ACB-10-146C13","doi-asserted-by":"publisher","DOI":"10.1159\/000292899"},{"key":"bibr-ACB-10-146C14","first-page":"43","volume":"1","author":"Orr KB","year":"1983","journal-title":"Diagn Immunol"}],"container-title":["Annals of Clinical Biochemistry: International Journal of Laboratory Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/acb.2010.010146","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1258\/acb.2010.010146","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/acb.2010.010146","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T11:56:07Z","timestamp":1777377367000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1258\/acb.2010.010146"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,10,7]]},"references-count":14,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2010,11]]}},"alternative-id":["10.1258\/acb.2010.010146"],"URL":"https:\/\/doi.org\/10.1258\/acb.2010.010146","relation":{},"ISSN":["0004-5632","1758-1001"],"issn-type":[{"value":"0004-5632","type":"print"},{"value":"1758-1001","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,10,7]]}}}
