Multiple primaries--Heme & Lymphoid Neoplasms: Is a new primary reported for the diagnosis of plasmacytoma associated with a pathological fracture if it follows a diagnosis five years ago of multiple myeloma? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: Is this one primary or two? Follicular lymphoma grade 1 (9695/3) on 8/23/12 from an abdominal lymph node. On 1/6/14 an abdominal lymph node biopsy showed diffuse large b cell lymphoma arising from high grade follicle center cell lymphoma. Patient has been on observation.
Multiple Primaries--Heme & Lymphoid Neoplasms: Should Rule M4 or the Heme DB be used to determine whether diffuse large B-cell lymphoma of the large intestine and peripheral T-cell lymphoma of the bone marrow represents one or two primaries? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: Would it be correct to apply rule M5 for a recurrence and abstract a single primary when a patient has a history of Hodgkin disease diagnosed in 2005 followed by a diagnosis of "recurrent Hodgkin and EBV+ Diffuse large B-cell lymphoma" in 2010? See Discussion.
Multiple Primaries--Lymphoma: How many primaries are abstracted for a patient with a 1995 periaortic lymph node biopsy showing lymphocytic lymphoma, diffuse small cleaved probable intermediate grade B cell positive, followed by stomach biopsies on 6/18/05 showing diffuse large B cell lymphoma and on 6/24/05 showing malignant lymphoma, tumor cells positive for [CD20] B cell respectively?
Multiple Primaries--Lymphoma: How many primaries should be reported when a left tonsil biopsy is diagnosed with marginal zone lymphoma (9699) and a cervical lymph node biopsy is diagnosed with marginal zone lymphoma and grade 3 follicular lymphoma (9699 and 9698)?
Multiple Primaries--Lymphoma: How many primaries should we abstract when Single Versus Subsequent Primaries table indicates one primary but special pathological studies indicate two primaries? See Description.
Multiple Primaries--Lymphoma: Is a diagnosis of mycosis fungoides followed a year later with a biopsy proven diagnosis of anaplastic large T-cell lymphoma stated to represent a transformation of the previous mycosis fungoides reportable as one or two primaries?
Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion.
Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
