It is unclear if code 300 is appropriate, since technically the fissure is comprised of pleura, involvement of the fissure appears to imply a tumor that is no longer localized.

An argument could be made for code 400, since the term traverses could be interpreted as crossing into adjacent lobe, however the lower lobe is not mentioned in this scan.

The Terms and Definitions Introduction discusses how these are older terms, but pathologists may still use them. In our region, pathologists do, in fact, still use these terms. Can these terms be added to Table 1? For registrars who do not reference the Introduction every time they code histology but go directly to Table 1, coding consistency would likely improve if such terms were added in the Table.

This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales.

There is no specific ICD-O-3 code for a which resulted in abstractors assigning the malignant astrocytoma, NOS code. These lesions were previously called but we are seeing the new terminology more frequently.

For example, a patient has a 2.6 cm breast tumor on MRI; a core biopsy measuring 0.7 cm is positive for infiltrating duct carcinoma. Rule #1 states "Use the largest measurement of the primary tumor from physical exam, imaging, or other diagnostic procedures before any form of treatment." However, Rule #9 seems to imply that size from an "incisional biopsy" takes precedence over imaging, even though it is known to be less than the entire tumor in size.

Histologic Type: HPV-associated multiphenotypic carcinoma. Overall, the morphology, immunohistochemistry, and HPV testing results support the diagnosis of an HPV-related multiphenotypic carcinoma. This entity has been described in the sinonasal region, where it behaves more indolently than its other salivary gland carcinoma counterparts (e.g., adenoid cystic carcinoma), with local recurrence but rare metastases.

Transurethral resection: Microscopic Diagnosis: Bladder, transurethral resection: Low-grade papillary urothelial carcinoma Gross Description: Received in formalin labeled with the patient's name and bladder tumor is a 3.0 x 2.0 1.0 cm aggregate of friable tan tissue biopsies. The specimen is submitted in toto, cassettes

This is all the information there is on this path report. Extent of Disease (EOD) instructions state inferred description of noninvasive: No statement of invasion (microscopic description present) SEER 2018 Appendix C Bladder Coding Guidelines state code behavior 3 if the only surgery performed is a transurethral resection of the bladder (TURB) documenting that depth of invasion cannot be measured because there is no muscle in the specimen OR the pathology report does not mention whether the submucosa is free of tumor or has been invaded by tumor.

The patient was clinically diagnosed with a pituitary adenoma on MRI in June 2009. The MRI noted an unusual contour involving the superior margin of the pituitary gland and the clinical interpretation was a small pituitary adenoma. The patient did not follow-up with the recommended repeat imaging and never received treatment for the pituitary adenoma.

The patient was eventually seen again in January 2020 and the MRI showed no adenoma in the pituitary gland. Since pituitary adenomas are known to spontaneously regress, should the 2009 diagnosis of pituitary adenoma be accessioned as a SEER reportable benign central nervous system (CNS) tumor?

Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease?

Should the updated Note 5 from the Non-malignant CNS regarding optic nerve glioma also be incorporated into Note 6 for Malignant CNS rules (the pilocytic astrocytoma note)?

This was one of the major issues identified in the SEER*Educate Workshop. Registrars have demonstrated they do not consistently think to look at the Non-malignant CNS schema when they see the term glioma and continue to misclassify optic nerve gliomas as malignant.

This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales.
