Multiple Primaries--Heme & Lymphoid Neoplasms: How many primaries should be reported when a 10/10/2017 skin biopsy identified myeloid sarcoma with monocytic differentiation, clinically stated to be leukemia cutis is followed by an 11/2/2017 BM biopsy showing an evolving high grade myelodysplastic process with atypical monocytes, likely an early evolving acute myeloid leukemia (AML), clinically stated to be a therapy-related AML (9920/3)? See Discussion.

Multiple primaries--Heme & Lymphoid Neoplasms: Is a new bone marrow diagnosis of acute myelogenous leukemia that follows a 2007 treated diagnosis of a JAK-2 positive polycythemia vera a new primary?

Multiple primaries--Heme & Lymphoid Neoplasms: Is a recently diagnosed granulocytic sarcoma followed by a diagnosis of AML two primaries? See Discussion.

Multiple primaries--Heme & Lymphoid Neoplasms: Is this 2 primaries? In 2011, a patient had a spinal mass biopsied positive for DLBCL and follicular lymphoma. The heme rules make this one primary coded as DLBCL. Patient had 2 rounds of chemo, but in 2014, he had a recurrent tumor in the same location. The 2014 biopsy was follicular lymphoma. Is this a new primary -- conversion of acute to chronic after treatment? Or is it the same, since FL was diagnosed in the original specimen?

Multiple primaries--Heme & Lymphoid Neoplasms: Is this abstracted as one primary or two?

5/2/13 Bone Marrow biopsy: myelodysplastic syndrome with approaching to acute myeloid leukemia with del 5q and 7q deletions. FISH: deletion of chromosome 5q and deletion of chromosome 7q detected.

I checked the Heme DB manual and there is no term "With approaching to". I checked the Multiple Primary calculator and it says new primary. My interpretation is that the myelodysplastic syndrome is in the process of transforming to acute myeloid leukemia.

Multiple Primaries--Heme & Lymphoid Neoplasms: Patient is diagnosed with myelodysplastic syndrome (MDS) with an early/evolving acute myeloid leukemia (AML) thought to be treatment related. Does rule M11 apply since there are two biopsies within 21 days, and therefore, two primaries, or one primary (9920/3)? See Discussion.

Multiple primaries--Heme & Lymphoid Neoplasms: Should a 2010 diagnosis of central nervous system diffuse large B-cell lymphoma be abstracted as a new primary when the patient has a history of cutaneous T-cell lymphoma in the 1980's and a 1991 history of DLBCL of the bowel (NOS)? See Discussion.

Multiple primaries--Heme & Lymphoid Neoplasms: Should the 2014 diagnosis be abstracted as a new primary since it is not mantle cell lymphoma and all of the types listed in the differential diagnosis would be a new primary? See discussion.

Multiple primaries--Heme and Lymphoid Neoplasms: Is a patient with peripheral blood initially showing chronic myelogenous leukemia (CML), lymph node biopsy showing granulocytic sarcoma (9930/3), and bone marrow biopsy showing acute myeloid leukemia (AML) one or two primaries? See Discussion.

Multiple Primaries--Lymphoma: How many primaries should be abstracted if DLBCL (9680/3) and Mantle Cell Lymphoma (9673/3) occur at the same time in different lymph nodes? How would Sequence be coded if the case is multiple primaries?
