1. Myeloproliferative conditions at the diagnostic interface between myeloproliferative neoplasms and non-neoplastic proliferations
Triple negative cases (JAK2, CALR and MPL negative) are particularly welcome. Cases associated with germline variants, as well as cases of hereditary or secondary polycythemia, are excluded.

2. AML and MDS with emerging disease-defining genetic alterations
Cases harboring genetic alterations with potential disease-defining significance that are not yet recognized as defining entities in current classification systems (ICC 2022 and WHO 5th edition), e.g., UBTF-TD, der(1;7), and SETBP1 mutations.

3. Mature large B-cell lymphomas with primary presentation in bone or exclusive involvement of the bone marrow
The focus is on mature large B-cell and/or high-grade lymphomas presenting primarily in bone or exclusively in the bone marrow. Follicular lymphomas are excluded.
