    Abstract Littoral cell angioma (LCA) is a rare endothelial cell neoplasm in the spleen. Although many cases of LCA are asymptomatic, some present with signs and symptoms related to splenomegaly, whereas others manifest with haematological abnormalities, including anaemia and/or thrombocytopaenia (ie, hypersplenism). We report a case of LCA presenting with chronic thrombocytopaenia, probably due to splenic sequestration of platelets or phagocytosis of platelets by neoplastic cells. Following therapeutic splenectomy, the patient suffered from a marked rebound thrombocytosis and subsequently developed pulmonary embolisms. He was treated with anticoagulant therapy combined with antiplatelet therapy, and his symptoms were quickly resolved. This case emphasises an exclusion of primary splenic disorders in patients with chronic thrombocytopaenia, especially in those with splenomegaly and the contemplation of thromboembolism prophylaxis postsplenectomy.

    Abstract Rare hematologic malignancies display evidence of both myeloid and lymphoid differentiation. Here, we describe such a novel bilineal event discovered in an adult woman with B-lymphoblastic leukemia (BLL). At the time of BLL diagnosis, the patient had a normal karyotype and a bulk sequencing panel identified pathogenic variants in BCOR, EZH2, RUNX1, and U2AF1, a genotype more typical of myeloid neoplasia. Additionally, the patient was noted to have 3-year history of cytopenias, and morphologic dyspoiesis was noted on post-treatment samples, raising the possibility of an antecedent hematologic disorder. To investigate the clonal architecture of her disease, we performed targeted sequencing on fractionated samples enriched for either B-lymphoblasts or circulating granulocytes. These studies revealed a truncal founder mutation in the spliceosome gene U2AF1 in both fractions, while distinct secondary mutations were present only in B-lymphoblasts (BCOR, NRAS) or myeloid cells (ASXL1, EZH2, RUNX1). These results indicate that both processes evolved from a common U2AF1-mutated precursor, which then acquired additional mutations during a process of divergent evolution and bilineal differentiation. Our findings highlight an atypical mechanism of BLL leukemogenesis and demonstrate the potential utility of fractionated sequencing in the characterization of acute leukemia.
