Primary Site--Brain and CNS: Are meninges surrounding cranial nerves cranial meninges [C700] or a part of the specific nerve's sheath? Is the primary site for an optic nerve sheath meningioma coded to optic nerve [C723] or cranial meninges [C700]?
Histology/Primary site--Heme & Lymphoid Neoplasms: How are these fields coded if a bone marrow biopsy demonstrates diffuse infiltration by B-cell lymphoma/leukemia which consists of medium-sized cells with Burkitt morphology and the flow cytometry has no evidence of leukemia or lymphoma?
MP/H Rules/Histology--Lung: How many primaries are accessioned if a pathology report for a right upper lobectomy with a chest wall resection describes the disease as 1) two foci of poorly differentiated non-small cell carcinoma, 2) mixed adenocarcinoma and non-mucinous bronchioalveolar carcinoma, each present as a separate focus? See Discussion.
MP/H Rules/Multiple primaries--Lung: Should a July 2011 left lower lobe mass with adenocarcinoma be accessioned as an additional primary per Rule M7 or as the same primary per Rule M12 if it is diagnosed subsequent to a September 2010 right upper lobe/right middle lobe lobectomy with clear cell adenocarcinoma in one nodule and adenocarcinoma in another nodule? See Discussion.
Reportability--Heme & Lymphoid Neoplasms: Does a change in the 2008 diagnosis from refractory anemia with excess blasts (RAEB I) to a subsequent diagnosis of RAEB II in 2011 need to be reported to the state if the Hematopoietic Database indicates these diagnoses represent the same primary?
Reportability/Histology--Heme & Lymphoid Neoplasms: Is a diagnosis of "small B-cell non-Hodgkin lymphoproliferative disorder" reportable? If so, how is the histology to be coded? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted, and what rule applies, when the patient has a 1999 diagnosis of Burkitt high grade B-cell lymphoma and was diagnosed in 2011 with diffuse large B-cell lymphoma? See Discussion
MP/H Rules/Histology--Lung: Per SINQ 20110115, why is micropapillary adenocarcinoma of the lung coded to 8260 [papillary adenocarcinoma] rather than 8050 [papillary carcinoma]?
MP/H Rules/Histology--Bladder: Can information from the CAP checklist that indicates, Tumor configuration: papillary be used to code histology to 8130 [papillary urothelial carcinoma] if the final diagnosis is also stated to be Bladder rumor: urothelial carcinoma and the pathologist stages the case as pTa [noninvasive papillary carcinoma]?
