Multiple Primaries (Pre-2007)--Breast: For a patient with a remote history of lobular breast carcinoma, would a new diagnosis of lobular breast carcinoma with DCIS be a new primary, even though the physician designates it as recurrent? See Description.

Multiple Primaries (Pre-2007)/Primary Site/EOD-Extension--Lung: Should lung cases be counted as more than one primary when nodules removed from separate lobes of the same lung have either the same histology or they are different immunophenotypes of the same main histologic classification (e.g., adenocarcinoma)? See discussion.

Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries?

Reportability/Recurrence (Pre-2007)--Bladder: If a patient has had recurrent invasive bladder cancers since 1971, should the latest recurrence in 2003 be SEER reportable because the case has yet to be reported to SEER?

Histology (Pre-2007)--Kidney, renal pelvis: What codes are used to represent the histologies of 1) "renal papillary (chromophil) carcinoma" and 2) "chromophil renal cell carcinoma?"

Histology (Pre-2007)/Primary Site/Diagnostic Confirmation: How would these fields be coded for a diagnosis of cholangiocarcinoma based on clinical findings only? See Discussion.

Multiple Primaries (Pre-2007): Is an in situ tumor followed by another in situ tumor in the same location a new primary? See discussion.

Multiple Primaries (Pre-2007)--Breast: When simultaneously diagnosed breast tumors of the same histology in the same breast are stated by the pathologist and/or clinician to be more than one primary, should these be reported as multiple primaries? See discussion.

Multiple Primaries/Histology (Pre-2007)--Colon: Would one primary be reported when adenocarcinoma arising in a polyp NOS [8210/3] and adenocarcinoma arising in a tubulovillous adenoma [8263/3] were simultaneously diagnosed in the sigmoid colon (first 3-digits of the histology are different)?

Multiple Primaries (Pre-2007): Is a small bowel carcinoid diagnosed 10 years after the diagnosis of metastatic carcinoid of unknown primary site a new primary or a new recurrence? See Description.
