Serositis as possible manifestation in MDS/AML patients with complex karyotype and TP53 mutation: case series.

Myelodysplastic syndromes (MDS) and Acute Myeloid Leukemia (AML) are increasingly recognized to exhibit immune dysregulation, which can occasionally present with autoinflammatory manifestations. We describe four patients with MDS/AML harboring p53 mutations and a complex karyotype who developed inflammatory serositis without infectious correlation. All patients showed clinical improvement following corticosteroid therapy.
