Update to Current Manual/Reportability--Biliary Tract: Is a diagnosis of high grade dysplasia of the gallbladder reportable? See Discussion.
Patient was diagnosed March 2024 with high grade dysplasia of the gallbladder during excision for clinical history of acute cholecystitis and obstruction.
Per the STR, Table 10 for Gallbladder and Extrahepatic Bile Duct Histologies shows Biliary intraepithelial neoplasia, high grade as code 8148/2. High grade glandular intraepithelial neoplasia of the biliary tract is also code 8148/2.
Recent SINQ 20240021 (GI specific) indicates high grade dysplasia is reportable as high grade glandular intraepithelial neoplasia (8148/2) for stomach, small intestine, and esophagus. Does the same hold true for gallbladder? If so, then it appears there is a conflict between STR and Appendix E2.
However, using the logic of SINQ 20240021 for this site would appear to contradict Appendix E2 which indicates high grade dysplasia in sites other than stomach, intestine, and esophageal sites is not reportable.
If we can code high grade dysplasia of GI sites to 8148/2, should we accession high grade dysplasia of the gallbladder and other biliary sites in a similar manner? If so, then Appendix E needs to be modified.
Report biliary intraepithelial neoplasia (dysplasia), high grade. As noted in SINQ 20240021 and the Other Sites Solid Tumor Rules, Rules H4/H26, the listed sites may not include all reportable neoplasms for 8148/2.
We will update the Other Sites Solid Tumor Rules to reflect this code as well as make revisions in the next release of the SEER Manual.
Histology/Behavior--Head and Neck: What is the histology code for sinonasal glomangiopericytoma in 2023? See Discussion.
6/8/2023
A. Left nasal mass: Sinonasal glomangiopericytoma B. Additional left nasal mass: Sinonasal glomangiopericytoma
Is this a borderline tumor? I am unable to find in this in the ICD-O-3 purple book or the Head and Neck Solid Tumor Rules.
Assign histology code 8815/3 per ICD-O-3.2. Sinonasal glomangiopericytoma is also referred to as a sinonasal hemangiopericytoma. Prior to 2021, it was coded as 9150/3.
Reportability--Brain and CNS: Is an optic nerve meningioma reportable if stated to arise in the “intraorbital segment” of the optic nerve meninges? See Discussion.
Patient was diagnosed on imaging with enhancement along the right optic nerve intraorbital segment, displacing the optic nerve, most consistent with optic nerve sheath meningioma.
Extracranial meningiomas are rare, however SINQ 20230052 does contain an exception for reportability in a different head and neck site because it is not an intracranial location.
It is unclear if this portion of the meninges surrounding the intraorbital optic nerve is still “intracranial” and thus reportable.
Report optic nerve sheath meningioma arising in the intraorbital segment. The optic nerve contains four segments, of which intraorbital is one. The WHO Classification of Eye Tumors, 4th edition, defines meningioma as a neoplasm originating from the meningothelial cells of the optic nerve leptomeninges. According to the Table 3 of the Non-malignant Solid Tumor Rules, all portions of the optic are reportable and meningiomas arising in the dura/meninges of an intracranial nerve are coded to cerebral meninges C700.
EOD/Prostate Pathologic Extension--Prostate: Is a pathology report from a prostate biopsy/transurethral resection of the prostate that states "with intraductal spread" extraprostatic/extracapsular extension or localized?
Code as a localized, intracapsular tumor as ductal carcinoma in situ does not invade. Intraductal spread is describing the neoplasm spreading through the acinar/ductal cells in the prostate specimen. It is an in-situ type of spread and not invasive but almost always presents with an invasive tumor.
