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.
1st primary, 8/23/12: Follicular lymphoma, grade 1 2nd primary, 1/6/14: Diffuse Large B Cell Lymphoma
Apply the multiple primary rules twice for this case. The 2012 diagnosis is follicular lymphoma. There are two histologies in 2014: diffuse large b cell lymphoma and follicle center cell lymphoma diagnosed at the same time in the same location. This is one primary per rule M4.
Then compare the 2012 diagnosis to the 2014 diagnosis.
Per the Hematopoietic Database, follicular lymphoma (all types) transforms to DLBCL. Per Rule M10, the DLBCL would be a second primary.
Multiple Primaries (Pre-2007)--Breast: Synchronous invasive right breast tumors. Ductal carcinoma, NOS in UIQ and Ductal carcinoma, tubular type in LOQ. Are these two primaries or a single primary coded to 8523/3?
For tumors diagnosed prior to 2007:
Code as two primaries, one 8500/3 [Infiltrating duct carcinoma] and one 8211/3 [Tubular carcinoma].
Apply the multiple primary rules first. These are synchronous right breast tumors with different histologies. Therefore, they are separate primaries according to rule 5.a on page 12 of the SEER Program Code Manual. ICD-O-3 histology code 8523/3 is NOT to be used to combine histologies from separate primaries; it is used for mixed histologies in a single primary.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Reportability--Lung: Is sclerosing hemangioma of the lung with multiple regional lymph nodes metastases reportable?
No, it is not reportable. According to the WHO Classification of Lung Tumours, sclerosing hemangioma "behaves in a clinically benign fashion...Reported cases with hilar or mediastinal lymph node involvement do not have a worse prognosis."
Date of Diagnosis--Colon: If a patient has a positive Cologuard test, is the date of diagnosis the date of the cologuard test or the date of the biopsy?
Do not use the date of a positive Cologuard test as the date of diagnosis.
Reportability/Histology--Pituitary Gland: How are Rathke cleft cyst and Rathke pouch tumor distinguished and are they both reportable?
Rathke cleft cyst is not reportable. Cysts are not neoplastic. However, Rathke pouch tumor (C751, 9350/1) is a reportable neoplasm for cases diagnosed 2004 and later. The Rathke pouch is coded to the pituitary gland. Benign and borderline pituitary tumors have been reportable since 2004.
Reportability/MP/H Rules/Histology--Ovary: What is the histology code for an ovarian tumor described as a mucinous borderline tumor, intestinal type?
Mucinous borderline tumor, intestinal type, of the ovary is not reportable. The behavior is /1. There is no applicable histology code for this histology when it ocurs in the ovary.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information.
EOD-Extension--Corpus Uteri: How do you code myometrial involvement described as 1) "to the level of the middle one-third" or 2) "superficial"?
For cases diagnosed 1998-2003:
Evaluate each case carefully.
1. Code the EOD-Extension field to 12 [Myometrium-inner half] because the pathology report indicates involvement of the myometrium "to the level of." However, if you feel that you cannot make that determination with certainty and you cannot ask a pathologist for clarification, then code the EOD-Extension field to 14 [Myometrium, NOS].
2. Code the EOD-Extension field to 12 [Myometrium-inner half] for cases with "superficial" myometrial invasion.
Reportability--Heme & Lymphoid Neoplasms: Is a case reportable in which the pathology report is negative for plasmacytoma but a subsequent physician's clinical diagnosis is plasmacytoma?
This case is reportable if the patient was treated for plasmacytoma. When the physician calls the case plasmacytoma and treats the patient accordingly, report the case.
See Case Reportability Instructions #6: Report the case when there is a clinical diagnosis (physician's statement) of a reportable hematopoietic or lymphoid neoplasm.
Note 1: The clinical diagnosis may be a final diagnosis found within the medical record or recorded on a scan (CT, MRI for example)
Note 2: Report the case even if the diagnostic tests are equivocal. A number of hematopoietic neoplasms are "diagnoses of exclusion" in which the diagnostic tests are equivocal and the physician makes the clinical diagnosis based on the equivocal tests and the clinical picture. See the Heme DB for definitive diagnostic methods for the specific neoplasm being abstracted.

EOD-Extension--Kaposi Sarcoma: Is a "markedly enlarged spleen" involvement for cases of Kaposi Sarcoma?
For cases diagnosed 1998-2003: No. Splenomegaly is not synonymous with "extension to" or "involvement of" the spleen in Kaposi's sarcoma. Look for a definite statement of Kaposi's lesion(s) involving the spleen.
