Histology--Heme & Lymphoid Neoplasms: How is histology coded for a diagnosis of composite lymphoma (follicular lymphoma and small lymphocytic lymphoma, BCL-2 positive)?
Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)] per Rule PH15. Code the histology to the non-Hodgkin lymphoma (NHL) with the numerically highest ICD-O-3 code when two or more NHLs are present in the same present in the same lymph node(s) or lymph node region(s), tissue(s), organ(s), or bone marrow. Both follicular lymphoma [9690/3] and SLL [9823/3] are types of NHL. Therefore, the histology is coded to 9823/3.
This composite histology represents a single primary per Rule M4. The rule states to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

Reportability--Cervix: The SEER Program Code Manual lists CIN III and carcinoma in situ of the cervix as not being reportable for cases diagnosed in 1996 or later, but does not list "adenocarcinoma in situ" or "squamous cell carcinoma in situ." Are these histologies still reportable?
For primary site cervix uteri, only histologies with behavior codes of 3 [invasive] are reportable to SEER for all registries.
Some SEER registries have opted to continue to collect behavior codes of 2 [in situ] for cervix uteri primaries.
CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius?
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 20
[Extension from other parts of lung to main stem bronchus, NOS
(EXCLUDES superficial tumor as described in code 11)
Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].
A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.
Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
Squamous cell carcinoma of the anus is reportable unless known or stated to be skin of anus.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded, and which PH rule applies, when chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is diagnosed simultaneously by biopsies of both lymph node(s) and the bone marrow?
Code the primary site to C421 [bone marrow] per Rule PH5 when CLL/SLL [9823/3] involves the bone marrow.
In the later stages of CLL/SLL, there may be involvement of bone marrow AND lymph node(s), lymph node region(s), organ(s), or tissue(s). As long as the peripheral blood and/or bone marrow are involved, the primary site is bone marrow.
WHO states that the diagnostic criteria for CLL versus SLL is not clearly defined. According to WHO guidelines, it is better to code to CLL/SLL and code the primary site to bone marrow when the marrow is involved and to lymph nodes, organ, or tissue when there is no bone marrow involvement.

Multiple Primaries--Hematopoietic, NOS: When the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that a disease is not a new primary, but a pathologist or clinician states that it is a new primary, do we use the physician information or the table?
For cases diagnosed prior to 1/1/2010:If the physician clearly states that this is a new primary, submit it as a new primary. Otherwise, use the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Primary Site--Lymphoma: How should this field be coded when a diffuse large B-cell lymphoma is found in the femur and in the soft tissue of the anterior chest wall but all CT scans are negative for lymphadenopathy?
For cases diagnosed prior to 1/1/2010:Code the Primary Site field to C809 [Unknown primary site]. The primary site of diffuse large B cell lymphoma can be either nodal or extranodal. The case described above is likely extranodal because there is no evidence of lymph node involvement. Because the extranodal site of origin is unknown, code the Primary Site to C809.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
2004 SEER Manual Errata/Grade--Colon/Bones: Is the term "pleomorphic" used to code tumor grade to 3 for selected primaries?
Delete the row containing the word "pleomorphic" from the tables on pages 93, C-219 and C-411. This correction will be included in the next set of replacement pages for the 2004 SEER manual.
EOD-Clinical Extension--Prostate: In the SEER EOD manual, there is a list of terms to distinguish apparent from inapparent tumor for prostate primaries. If a physician uses a term not currently on the list or if a physician uses a list in the "maybe" category, should we assume the tumor to be clinically inapparent or clinically apparent tumor?
For cases diagnosed 1998-2003:
If the physician used a term not on the clinically apparent/inapparent list, ignore that term and use the best information available from other sources to code the EOD-Extension field.
If clarifying stage information is missing and the term is in the maybe category or the term is not on the list, then code EOD-Extension as 30 [localized, NOS] for cases that appear localized.
