Primary site--Heme & Lymphoid Neoplasms: What primary site and heme rule applies when a PET scan shows bilateral renal masses, hypermetabolic liver lesions and retroperitoneal lymphadenopathy, a right kidney biopsy was positive for diffuse large B-cell lymphoma, and the bone marrow biopsy was negative? See Discussion.

Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of multifocal Langerhans cell histiocytosis with involvement of the bone, liver, spleen and retroperitoneum?

Reportability--Heme & Lymphoid Neoplasms: Is plasma cell dyscrasia reportable and synonymous with multiple myeloma? See Discussion.

Reportability--Heme & Lymphoid Neoplasms: Is reactive plasmacytosis a reportable diagnosis that is equivalent to plasmacytoma?

Ambiguous Terminology/Histology--Heme & Lymphoid Neoplasms: How are the histology and diagnostic confirmation to be coded when the pathology report's final diagnosis is "plasma cell dyscrasia consistent with plasma cell myeloma" and the physician subsequently states this diagnosis was plasma cell myeloma? 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.

Primary site--Heme & Lymphoid Neoplasms: How is primary site coded for bilateral pelvic lymph node involvement for lymphoma primaries?

Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are reported if a 2010 inguinal lymph node biopsy diagnosis of follicular lymphoma, grade 1 is subsequently diagnosed in 2012 with a 50% follicular, grade 3 and 50% diffuse large B-cell via a biopsy of an axillary mass?

Multiple primaries/Histology--Heme & Lymphoid Neoplasms: Is there a timing rule used to recode histology should a more specific diagnosis of refractory anemia with excess blasts (RAEB) be confirmed after an initial diagnosis of myelodysplastic syndrome (MDS)? How many primaries are abstracted if RAEB subsequently evolves toward an acute myeloid leukemia? See Discussion.

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a patient originally diagnosed with CLL is subsequently diagnosed several months later on a bone marrow biopsy with Richter's syndrome that transformed into a large cell lymphoma? See Discussion.
