Per Rule M8, this is a single primary as there are multiple urothelial tumors as outlined in Table 1 (papillary urothelial carcinoma [8130] and sarcomatoid urothelial carcinoma [8122]) simultaneously present in multiple urinary organs (bladder, ureter and renal pelvis). As Rule M8 indicates these are a single primary, despite the histologies differing at the third digit (8130 vs 8122), then Rule H14 (Code the histology of the most invasive tumor) seems to be the most applicable histology rule. Following Rule H14 (in the Text version of the MP/H Rules), the histology would be coded as 8122 (sarcomatoid urothelial carcinoma) since the renal pelvis tumor was the most invasive tumor present.

However, in both the Matrix and Flowchart versions of the MP/H Rules, Rule H14 contains a note (missing from the Text version) that states that this rule should only be used when the first three numbers of the histology codes are identical (This is a single primary). Rule M8 clearly tells us these are a single primary, despite the differences at the third digit of the histology. Further defaulting to Rule H15 (Code the numerically higher histology code) in this case would ignore the histology of the tumor with the worse prognosis (the most invasive tumor). Was this note included in the Matrix and Flowchart versions in error?

CT-guided liver biopsy, diagnosis: Metastatic neuroendocrine carcinoma. Diagnosis Comment: Cytology of the tumor appears to be low to intermediate grade.

Would this case be coded as an atypical carcinoid tumor (8249/3) based on SINQ 20170033 and the statement of intermediate grade; or should this be 8240/3 (neuroendocrine tumor) per SINQ 20160023 because it is a metastatic site? More clarification is needed on when to code 8249/3 or 8240/3 for a neuroendocrine carcinoma or neoplasm seen in a metastatic specimen only when there is specified grade.

The physician consult in this case further specifies that the large granular lymphocyte disorder represents an autoimmune disease of autoimmune T-cell mediated mechanism. Is this a reportable diagnosis?

Pathology report microscopic description: The tumor is a meningothelial neoplasm (EMA+; BCL-2 and CD34 negative) with prominent collagen deposition. Necrosis and prominent nucleoli are present; no other atypical features are seen. Mitoses are present, up to 2 per 10 high-powered fields. Final Diagnosis: Dura, bicoronal craniotomy (specimen A): Meningioma with atypical features.

There is no rule in benign brain and CNS section of Multiple Primary/Histology (MP/H) Rules stating to code the most specific histologic term when the diagnosis is (something less specific, i.e., adenocarcinoma). This rule is in other site chapters of MP/H but appears missing in the benign brain and CNS section.

Pathology report diagnosis: Urethral lesion: Intraductal carcinoma of the prostate, see microscopic. Clinical Information: Urethral Lesion/Hematura. Microscopic Description: The biopsy shows dilated ductal structures filled with anaplastic epithelium showing areas of comedo-type necrosis. The tumor cells have enlarged nuclei prominent nucleoli and mitoses are identified. Surrounding benign prostatic tissue is also present. Immunostains show that the tumor cells stain for PSA, PSAP, P504s but are negative for GATA-3. The other components of the PIN 4 stain CK5/14 and P63 stain the basal cells surrounding the tumor confirming the intraductal nature of the process. Intraductal carcinoma should not be confused with high grade PIN as the former is usually associated with high grade invasive tumor. Is this C619 and 8500/2?

I recently did a presentation on coding the data item Race. In my presentation I discussed understanding geography help code race in some circumstances. One of the slides demonstrates how large Polynesia is and what Pacific islands are found in Polynesia, such as, Tahiti, Samoa, and even Hawaii, all of which have their own codes. Someone in the audience asked "How do you code New Zealand? Upon some research, New Zealand is not listed in Appendix D of the SEER coding manual. We could code them 01-White. But research shows there is a very large indigenous population. Technically, New Zealand is located within the boundaries of Polynesia - Code 25 (Polynesian).

At the central registry, we have accessioned this scenario as three primaries per Multiple Primaries/Histology (MP/H) Rule M10 (diagnosed more than 1 year apart), as the patient was stated to be disease free between each occurrence. However, the diagnosing/treating facility is not reporting these cases due to clinical statements of recurrent disease.

This is an example of a case type identified on casefinding audits conducted by our central registry in which we have learned SEER's expectation of MP/H rule application does not match hospital reporting. Can the 2018 version of the MP/H rules more clearly address how this type of clinically recurrent (multiple times) case should be handled?

We are seeing the term "incidentaloma" on magnetic resonance imaging (MR) reports of head and also with physician statements. For example, this MR of the head: Impression--Suboptimal study due to motion degradation. Heterogeneously enhancing pituitary gland without evidence of acute abnormality. A 3 mm focus of relative hypoenhancement in the left gland is favored to represent an incidentaloma. Advise correlation with clinical findings.

Also, there are cases where the scans show meningioma and then at a later date it is stated to be an incidentaloma in physician notes.

Is the term "incidentaloma" alone reportable, if the term "tumor" for CNS cases is never stated? When I googled the term, it is stated to mean "tumor."
