We present the first case of an MCT associated with IgA-mediated AIHA. We discuss the diagnostic challenges of patients presenting with a direct antiglobulin test negative AIHA picture and the importance of reviewing these cases with the local transfusion laboratory. We also review the treatment options for MCT associated AIHA. In particular, we note they are typically resistant to immunosuppression and that surgical resection should be considered at an early stage. Although MCTs are a rare cause of AIHA, they can be treated easily and should be excluded in young women presenting with AIHA, especially if resistant to corticosteroids.<\/jats:p>","DOI":"10.1136\/bcr-2021-243017","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T12:30:33Z","timestamp":1646137833000},"page":"e243017","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["DAT negative warm autoimmune haemolytic anaemia secondary to a mature cystic teratoma refractory to immunosuppressive therapy"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5351-9581","authenticated-orcid":false,"given":"Nicholas","family":"Denny","sequence":"first","affiliation":[{"name":"Haematology, Oxford University Hospitals NHS Foundation Trust, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Gordon","sequence":"additional","affiliation":[{"name":"Haematology, Oxford University Hospitals NHS Foundation Trust, Banbury, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oyewale","family":"Atoyebi","sequence":"additional","affiliation":[{"name":"Haematology, Oxford University Hospitals NHS Foundation Trust, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,3,1]]},"reference":[{"key":"2025082707143811000_15.3.e243017.1","doi-asserted-by":"crossref","first-page":"395","DOI":"10.1111\/bjh.14478","article-title":"The diagnosis and management of primary autoimmune haemolytic anaemia","volume":"176","author":"Hill","year":"2017","journal-title":"Br J Haematol"},{"key":"2025082707143811000_15.3.e243017.2","doi-asserted-by":"crossref","first-page":"208","DOI":"10.1111\/bjh.14654","article-title":"Guidelines on the management of drug-induced immune and secondary autoimmune, haemolytic anaemia","volume":"177","author":"Hill","year":"2017","journal-title":"Br J Haematol"},{"key":"2025082707143811000_15.3.e243017.3","doi-asserted-by":"crossref","DOI":"10.1136\/bmj.1.4041.1305","article-title":"Failed splenectomy in acholuric jaundice and the relation of toxaemia to the haemolytic crisis","volume":"1","author":"West-Watson","year":"1938","journal-title":"Br Med J"},{"key":"2025082707143811000_15.3.e243017.4","doi-asserted-by":"crossref","DOI":"10.1136\/bcr.06.2009.1971","article-title":"Warm antibody autoimmune haemolytic anaemia associated with ovarian teratoma","volume":"2010","author":"Raimundo","year":"2010","journal-title":"BMJ Case Rep"},{"key":"2025082707143811000_15.3.e243017.5","doi-asserted-by":"crossref","first-page":"596","DOI":"10.1016\/j.annemergmed.2008.10.022","article-title":"Sickle cell anemia and pain: will data prevail over beliefs?","volume":"53","author":"Payne","year":"2009","journal-title":"Ann Emerg Med"},{"key":"2025082707143811000_15.3.e243017.6","first-page":"504","article-title":"Autoimmune hemolytic anemia associated with benign ovarian cyst: a case report and review of literature","volume":"57","author":"Agarwal","year":"2003","journal-title":"Indian J Med Sci"},{"key":"2025082707143811000_15.3.e243017.7","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/105.5.567"},{"key":"2025082707143811000_15.3.e243017.8","doi-asserted-by":"crossref","first-page":"365","DOI":"10.3346\/jkms.2006.21.2.365","article-title":"A case of autoimmune hemolytic anemia associated with an ovarian teratoma","volume":"21","author":"Kim","year":"2006","journal-title":"J Korean Med Sci"},{"key":"2025082707143811000_15.3.e243017.9","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810801)48:3<721::AID-CNCR2820480311>3.0.CO;2-U"},{"key":"2025082707143811000_15.3.e243017.10","doi-asserted-by":"crossref","unstructured":"Saida T , Mori K , Masumoto T .
