Reportability--Brain and CNS: Is pseudotumor cerebri reportable?
Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor.
Reportability--Brain and CNS: Is schwannoma of the extracranial part of a cranial nerve reportable? Some cranial nerves, like facial nerve, have intracranial and extracranial branches.
An extracranial schwannoma is not reportable. The schwannoma must arise on the intracranial part of the nerve to be reportable.
Reportability--Brain and CNS: Is this diagnosis reportable? If this neoplasm originated in the spinal cord, it is reportable, correct?
Specimen is described as a 'spinal cord mass.' The final diagnosis is 'fragments of adipose tissue demonstrating vascular proliferations consistent with angiolipoma. No histologic evidence of malignancy.' The microscopic description says: Sections of the spinal mass reveal bone, cartilage, fibrous tissue and adipose tissue. The adipose tissue demonstrates increased vascularity with thin walled blood vessels seen with islands of delicate fibrous stroma. The histologic findings are compatible with fragments of angiolipoma.
The neoplasm is reportable if it originated in the spinal cord or is intradural (within the spinal dura; spinal nerve roots are intradural). If there is not enough information to determine the exact site of origin, do not report the case.
Reportability--Brain and CNS: Why has reportability changed for "intradural extramedullary schwannomas"? Are all "spinal" schwannomas reportable or only those stated to be "intradural"? See Discussion.
If intradural schwannomas are to be collected for cases diagnosed 2011 and later, why were they not included in the 2012 SEER Manual? Should collection of spinal schwannomas be postponed until the next revision of the MP/H Rules?
The reportability of schwannomas was not initially agreed upon by the standard setters. After the issue was discussed by the CoC, NPCR and SEER Technical Workgroup and an agreement was reached. See #2 under Reportability in the Data Collection Answers from the CoC, NPCR, SEER Technical Workgroup http://www.seer.cancer.gov/registrars/data-collection.html#reportability.
The most accurate and most current instruction is to report these spinal tumors when they arise within the spinal dura or spinal nerve roots, or when they are stated to be "intradural" or "of the nerve root." Do not report these tumors when they arise in the peripheral nerves. The peripheral nerves are the portion of nerve extending beyond the spinal dura.
Spinal cord intradural schwannomas originate in spinal nerve roots. Spinal nerve root is best classified as spinal cord, C720.
Reportability--Brain and CNS: Is an MRI finding of “statistically meningioma” reportable? See Discussion.
Example: Patient has a 2023 brain MRI described as having a “new dural based nodule, statistically meningioma, along the left distal tentorial incisura.” All subsequent chart information is related to patient’s unrelated diagnosis of multiple sclerosis only.
Is the terminology “statistically” reportable ambiguous terminology in this context?
If you cannot clarify this with the involved physicians, do not report this case of meningioma based on information provided. There is no indication that the patient was treated or further evaluated for meningioma.
Reportability--Brain and CNS: Is "Lhermitte-Duclos disease" is reportable? See discussion.
The MRI states "Lhermitte-Duclos disease" but does not include "dysplastic gangliocytoma of cerebellum"; is this the same as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)"?
"Lhermitte-Duclos disease" alone can be interpreted as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)" and reportable. The WHO classification for CNS tumors lists this entity as "Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease)" signifying that the terms are used synonymously.
Reportability--Brain and CNS: Is a thalamic amyloidoma reportable if so what histology code is used?
Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings.
Reportability--Brain: Is benign lymphangioma of the brain (9170/0) reportable? It is not on the list of non-malignant blood vessel tumors in the National Program of Cancer Registries Clarifications for Central Nervous System (CNS) tumors.
Lymphangioma of the brain or CNS is not reportable. Lymphangioma is a malformation of the lymphatic system. Even though it has an ICD-O-3 code, do not report it.
Final Dx for left Breast biopsy: Atypical epithelial proliferation (ADH/DCIS). Comment: Sections show small focus of atypical epithelial proliferation with features of atypical duct hyperplasia/low grade duct carcinoma in-situ.
ADH/DCIS is reportable. DCIS (duct carcinoma in situ) is a reportable neoplasm. When DCIS is stated as the final diagnosis, report the case.
Reportability--Breast: Is a final path diagnosis of "phyllodes tumor, borderline (malignant, low grade)" reportable if the comment states "Features favor the diagnosis of a borderline phyllodes tumor (or also called malignant phyllodes tumor of low grade)"?
No, borderline phyllodes tumors (PT) are not reportable. The ICD-O-3 code is 9020/1. According to the WHO Classification of Tumours of the Breast and Female Genital Organs, borderline PT's are also called low grade malignant PT's.
