Most commonly it precedes acute myeloid leukaemia but occasionally occurs simultaneously. It may also be associated with myeloproliferative neoplasms, myelodysplastic syndrome and the blast phase of chronic myeloid leukaemia. The most common sites for extramedullary tumours are bone, periosteum, soft tissue, lymph node and skin. Although this disease can affect a wide range of body sites, there are very few reports of peritoneal myeloid sarcoma or cavity effusion. The authors present the case of a 68-year-old man with myelodysplasia-related acute myeloid leukaemia and peritoneal myeloid sarcoma with myeloid ascites. The definitive diagnosis is challenging, requires a high level of suspicion, and relies on the exclusion of all alternative diagnoses and especially on complementary tests such as flow cytometry and immunohistochemistry analysis of ascitic fluid in order to detect the immature myeloid cells.<\/jats:p>","DOI":"10.12890\/2022_003184","type":"journal-article","created":{"date-parts":[[2022,2,17]],"date-time":"2022-02-17T04:24:41Z","timestamp":1645071881000},"source":"Crossref","is-referenced-by-count":0,"title":["Leukaemic Ascites and Peritoneal Myeloid Sarcoma: Rare but Not Impossible"],"prefix":"10.12890","volume":"9","author":[{"given":"Lu\u00eds","family":"Landeiro","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Hospital da Luz Lisboa, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiago","family":"Neto Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Hospital da Luz Lisboa, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margarida","family":"Proen\u00e7a","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Hospital da Luz Lisboa, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albertina","family":"Nunes","sequence":"additional","affiliation":[{"name":"Hematology Department, Instituto Portugu\u00eas de Oncologia Francisco Gentil, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Bay\u00e3o Horta","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Hospital da Luz Lisboa, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2022,2,16]]},"reference":[{"key":"10.12890\/2022_003184_ref1","doi-asserted-by":"crossref","unstructured":"<li>Arber DA.
