Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.

For tumors diagnosed prior to 2007:

Assign code 8560/33 [Adenosquamous carcinoma, poorly differentiated]. "Glandular" carcinoma is a synonym for adenocarcinoma. Mixed adenocarcinoma and squamous carcinoma is coded to 8560. Do not use code 8255 [Adenocarcinoma with mixed subtypes] when a more specific complex code is available.

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:

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.

Report ovarian mucinous borderline tumor with foci of multifocal intraepithelial carcinoma. The foci of intraepithelial carcinoma makes this reportable. See the list of synonyms for in situ in the SEER Manual, Behavior Code data item.

Report two primaries: MALT lymphoma and signet ring carcinoma. Use the 2007 MP/H rules and the Heme rules for this case.

This case could be an example of a "collision tumor" - two separate tumors that grow together into one mass. Collision tumors are a rare exception to rule M2 in the MP/H rules.

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.

"Erosion" is not synonymous with "ulceration" when coding CS extension for breast.

Regarding the term "grade 0" for an immature teratoma, determine whether the pathologist is using that term to describe the primary tumor or its implants. The term can be used to describe both situations.

An immature teratoma (IT) may have grade 0 (benign) implants. Grade 0 implants may affect the prognosis and treatment, but the primary tumor (IT) would still be malignant and therefore reportable. If grade 0 pertains to the primary tumor (as opposed to implants) it is benign, and therefore not reportable.

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

This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.

The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

Yes, this case is reportable. It is invasive (invasion into the lamina propria).

According to the WHO Classification of Urinary System Tumours, "Most pT1 cancers are papillary, low or high grade."
