Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].

Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).

Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma.

Unless the disease is specified as primary, idiopathic, essential, or the physician states there is a myeloproliferative neoplasm, the term thrombocytosis, NOS is not reportable. Thrombocytosis, NOS, is the presence of high platelet counts in the blood. Thrombocytosis can be associated with chronic infections and other diseases as well as with myeloproliferative disease. Thrombocytosis, NOS is listed in Appendix F as a Non-Reportable Term.

See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.

If the only information available is "Grade 2," assign code 2 [Grade II].

For tumors diagnosed prior to 2007:

There are two primaries in this example:

1. Invasive lobular carcinoma [8520/3]

2. In situ Paget disease of nipple [8540/2].

There is no combination code for lobular carcinoma and Paget disease.

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

This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

Code the histology to 9591/3 [B-cell lymphoma, NOS].

After searching the Heme DB for the term , no B-cell leukemia/lymphoma NOS code is found. However, the diagnosis of B-cell lymphoblastic leukemia/lymphoma is found. This case scenario does not specify that this is a lymphoblastic leukemia/lymphoma; therefore, the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied.

A subsequent search of the Heme DB for the term returns "Non-Hodgkin lymphoma, NOS" [9591/3]. Under the Alternative Names section of the Heme DB, B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Therefore, the B-cell lymphoma NOS code [9591/3] is the most appropriate histology code to use for this case.

This will be added to the next revision of the Heme DB and Manual.

This case should be accessioned as one primary. Per Rule PH26, code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow. (We assumed all available physical exams, scans, and other work-up were negative for lymph node, tissue, or organ involvement.) Histology is coded to 9680/3 [Diffuse large B-cell lymphoma (DLBCL)]. Under the Alternate Names section of the Heme DB, a synonym for DLBCL is B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.

There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.

Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.
