20021013 | Histology (Pre-2007)--Breast: What code is used for histology "tubular carcinoma with lobular carcinoma in situ"? | For tumors diagnosed prior to 2007:
Assign code 8211/3 [Tubular carcinoma]. According to histology rule #2 for a single tumor on page 86 of the 2004 SEER manual, code the invasive histology when both invasive and in situ tumor are present.
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. |

20031150 | Histology (Pre-2007)--Breast: Should the histology "non-invasive papillary carcinoma" along with the comment "solid intraductal papillary proliferation includes cytologically atypical cells with scattered mitotic figures" be coded to 8503/2 [intraductal papillary carcinoma] or 8050/2 [papillary carcinoma in situ]? | For tumors diagnosed prior to 2007:
The best histology code for this breast case is 8503/2 [Noninfiltrating intraductal papillary carcinoma]. According to the WHO Classification of Tumors for Breast, Papillary carcinoma, non-invasive is a synonym for Intraductal papillary carcinoma. Further, code a more specific histologic type when found in the microscopic description, according to the SEER Program Code manual.
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. |

20061085 | Histology (Pre-2007)--Breast: Is histology coded from the more representative specimen or should the combination code 8522/3 [Infiltrating duct and lobular carcinoma] be used for a case in which a right breast mass needle core biopsy revealed infiltrating ductal ca, grade III and the subsequent right mastectomy revealed a 2.3 cm lobular carcinoma? | For tumors diagnosed prior to 2007:
Code the histology using the final diagnosis on the pathology report of the procedure that resected the majority of the primary tumor. In this case, the mastectomy removed more of the tumor than the needle biopsy. The final diagnosis from the mastectomy is infiltrating lobular carcinoma. Code histology to 8520/3 [lobular carcinoma].
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. |

|
20051008 | Histology (Pre-2007)--Breast: Is a "noninvasive papillary carcinoma, solid type, of the breast" coded to 8503/2 [noninfiltrating intraductal papillary carcinoma] or 8230/2 [Intraductal carcinoma, solid type]? | For tumors diagnosed prior to 2007:
Code histology to 8503/2 [Noninfiltrating intraductal papillary adenocarcinoma]. "Solid" is one of four subtypes of intraductal papillary carcinoma. The other subtypes are cribriform, micropapillary and spindle cell. ICD-O-3 does not provide codes for each intraductal papillary subtype, so code to intraductal papillary carcinoma.
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. |

|
20071008 | Histology (Pre-2007)--Breast: How is "invasive lobular carcinoma with signet ring cell features (95%) and ductal features (5%)" coded for a single tumor diagnosed prior to 2007? | For cases diagnosed 1/1/04-12/31/06, code histology to 8524 [Lobular mixed with other types of carcinoma]. Assuming there is no mention of in situ, Histology Coding Rule 3 applies: Use a mixed histology code if one exists
For cases diagnosed 2007-2014, 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. |

20021122 | Histology (Pre-2007)--Breast: For a path diagnosis of ductal carcinoma in situ, cribriform type with apocrine features, does the term "apocrine" modify the term cribriform or does it represent another type of ductal carcinoma in situ? See discussion. | It can be difficult to determine if two terms mentioned in a pathology report are describing different aspects of the same morphology or if the two terms are describing two different morphologies. | For tumors diagnosed prior to 2007:
Code the Histology field to 8401/2 [Apocrine carcinoma in situ]. According to our pathologist consultant "Because apocrine is the more unusual tumor, and pulling it out of the cribriform category keeps the latter a little cleaner (because most cribriform ductal carcinoma in situ is not particularly apocrine), I am inclined to code to the histology to apocrine ductal carcinoma in situ."
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. |

|
20010103 | Histology (Pre-2007)--Breast: Are diagnoses of "infiltrating duct and mucinous carcinoma" and "duct carcinoma, mucinous type" both coded to the histology code of 8523/3? | For tumors diagnosed prior to 2007:
Code "Infiltrating duct and mucinous carcinoma" to 8523/3 [Infiltrating duct mixed with other types of carcinoma] according to the instructions for coding a single tumor with complex histology in Appendix C of the 2004 SEER manual. Assign code 8523/3 when the diagnosis is duct carcinoma mixed with another type of carcinoma. Look for "and" or "mixed" in the diagnosis. Code the Histology field for a "ductal carcinoma, mucinous type" to 8480/3 [Mucinous carcinoma]. The instructions for coding a single tumor with complex histology are to code the specific type if the diagnosis is "Duct carcinoma, _____ type."
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. |

20041104 | Histology (Pre-2007)--Bladder: What is the correct histology code for this tumor of the bladder? See Discussion. | TURBT was performed with invasive residual tumor remaining - path report reads "Mixed carcinoma of the urinary bladder, with components of invasive high grade urothelial carcinoma, invading deep muscle, and small cell carcinoma." | For tumors diagnosed prior to 2007:
Code combined small cell carcinoma [8045]. This mixed carcinoma is both urothelial and small cell. It is important to capture the small cell information in the code because the prognosis for small cell is different from pure urothelial carcinoma.
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. |

20021190 | Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion. | Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict). | For tumors diagnosed prior to 2007:
Please see SEER Inquiry question ID number 20041104.
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. |

|
20061021 | Histology (Pre-2007)--Bladder: How is a "carcinoma with squamous, mucinous, and signet ring cell features" coded? | For tumors diagnosed prior to 2007:
Code histology to 8490 [Signet ring cell carcinoma]. Rule 7 on page 87 of the 2004 SEER Manual applies to this case.
Rule 7: Code the numerically higher ICD-O-3 code. This is the rule with the lowest priority and should be used infrequently.
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. |
