For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Appendix F, monoclonal B-lymphocytosis of uncertain significance (MLUS) is not reportable.

Some papers point out that a lymphocyte count less than five thousand is equivalent to monoclonal B-lymphocytosis of uncertain significance (MLUS) or monoclonal B-cell lymphocytosis (MBL). A lymphocyte count of five to thirty thousand could be smoldering chronic lymphocytic leukemia (CLL). The diagnosis of MLUS is a benign process that does not meet the criteria for CLL.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

Tubular adenoma with high grade dysplasia and focal invasion is reportable. Assign the histology code and behavior as 8210/3 (Adenocarcinoma in tubular adenoma).

NAACCR Guidelines for ICD-O-3 Implementation discuss the term high grade dysplasia (without invasion). High grade dysplasia and related terms are under review and study for consideration as a reportable neoplasm. Registries should check with their state reporting legislation to see if included in the reporting requirements.

For solid tumors, ignore the term "evolving" and apply the registry rules for reportability to this case. Squamous cell carcinoma of the vermillion border of the lower lip (C001) is reportable.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

For tumors diagnosed prior to 2007:

Based only on the information provided above,

1. The CS extension code is 07 [Paget disease of nipple (without underlying invasive carcinoma pathologically)].

2. The SS 2000 stage is 1 [Localized].

3. The histology code is 8543 [Paget disease and intraductal carcinoma of breast]. The behavior code is 3 [Malignant].

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.

For tumors diagnosed prior to 2007:

Unless it is stated to be a RECURRENT or METASTATIC melanoma, record each melanoma as a separate primary when:

1. The occurrences are more than two months apart.

2. The fourth digit of the ICD-O topography code for skin [C44._] is different .

3. The first three digits of ICD-O-3 morphology code are different.

4. An in situ melanoma is followed by an invasive melanoma.

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.

For tumors diagnosed prior to 2007:

If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.

If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate 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.

Malignant hidroacanthoma simplex of the scalp is reportable. Malignant hidroacanthoma simplex is a synonym for porocarcinoma, 8409/3.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Yes. Code CS Extension-Clinical Extension to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)] for clinically inapparent prostate cancer with positive apex biopsy.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension.
