Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: Would the simultaneously occurring histologies of "high grade ductal carcinoma in situ with micro invasion" and "keratinizing squamous cell carcinoma" be coded as two primaries or as a single primary when the pathologist is not clear whether two separate tumor masses exist?
For tumors diagnosed prior to 2007:
Code as two primaries, assuming the tumors are separate and the margins are clear/negative. Code 8071/3 [Invasive squamous cell ca, keratinizing] and 8500/3 [Ductal carcinoma, "microinvasive"].
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.
EOD-Extension--Pancreas: Should these terms be ignored when coding extension to 10 or 30, or do they indicate involvement for non-surgically treated pancreas primaries?
1) Stricture of the common bile duct
2) Common bile duct is narrowed
3) Common bile duct is obstructed
4) Common bile duct dilation
5) Malignant stricture of the common bile duct
6) Ampullary or common bile duct stricture with a negative biopsy or brush.
For cases diagnosed 1998-2003:
Ignore these terms when coding extension to 10 or 30. These terms do not verify involvement by pancreatic cancer of the organs mentioned. Other non-malignant circumstances could cause these conditions.
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
Place of Birth: When there is conflicting information, which record takes precedence in coding this field, the medical record or the death certificate?
If there is a discrepancy, use the information from the medical record to code the Place of Birth field. The information from the medical record is provided by the patient, the information on the death certificate is provided by others. If the medical record does not contain birth information, use the information from the death certificate.
Reportability--Heme & Lymphoid Neoplasms: Is Rosai-Dorfman's syndrome (histiocytosis) a reportable malignant condition?
Rosai-Dorfman disease is not reportable. Rosai-Dorfman disease is a rare non-neoplastic disease. This disease can mimic lymphoma and extranodal involvement is frequent.
Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes?
For cases diagnosed 1998-2003:
If only the extramedullary site is involved, such as colon, code the Primary Site field to the site of origin. Granulocytic or myeloid sarcoma is an exception to the rule that all leukemias should be coded to bone marrow as the primary site. Granulocytic sarcoma is a deposit of malignant myeloid cells in a site other than bone marrow (extramedullary). For EOD staging, granulocytic sarcoma [9930/3] is included in the Hematopoietic, Reticuloendothelial, Immunoproliferative and Myeloproliferative Neoplasms scheme and the Extension field is coded to 10 when the lymph nodes are negative, since it (like solitary plasmacytoma) is a localized deposit of tumor.
However, if the regional lymph nodes associated with the extramedullary primary site are involved, code the EOD-Extension field to 80 [Systemic disease] because the disease is no longer an isolated deposit of malignant granulocytes (in other words, it is not localized).
The EOD-Lymph Nodes field is coded to 9 regardless of whether or not the lymph nodes are involved because that is the only allowable code for that field.
Histology (Pre-2007)--Skin: Are "atypical melanocytic hyperplasia" and "severe melanotic dysplasia" synonyms for melanoma in situ?
For tumors diagnosed prior to 2007:
No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or 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.
Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?
Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.
Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

Primary site--Heme & Lymphoid Neoplasms: When only pathology reports are available, how should the primary site be coded when a both a bone marrow biopsy and colon biopsy demonstrate "mantle cell lymphoma"?
For this case, code primary site to C189 [colon, NOS] per Rule PH24.
Mantle cell lymphoma usually begins with lymph node involvement and spreads to other tissue. However, it can begin in a lymphocyte such as those in the GI tract. Per the Abstractor Notes section in the Heme DB, patients usually present with advanced disease. About half will have some combination of B symptoms. Swelling of lymph nodes and spleen are usually present. Bone marrow, liver and GI tract involvement occurs in a very high percentage
