Reportability--Brain and CNS: Is Langerhans cell histiocytosis [9751/1] of the meninges [C709] reportable?
For cases diagnosed prior to 1/1/2010:Yes. The criteria for reportable benign/borderline CNS tumors is based on location (site) and behavior (benign/borderline). There is no caveat for histologic type. Therefore, this would be reportable as these tumors have been reported arising from the meninges or choroid plexus.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.
Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?

Reportability depends on the location of the tumor. Tumors in the following sites are reportable:
C700 - C709
C710 - C719
C720 - C729
C751 - C753
Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.
Reportability--Brain and CNS: For von Hippel Lindau disease with multiple hemagioblastomas, is each hemangioblastoma reportable as a new primary? See Discussion.
Diagnosis of von Hippel-Landau disease, multiple brain surgeries between 2002 and 2007 for recurring hemangioblastomas, 9161/1. This disease manifests as multiple (recurring) hemangioblastomas.
For cases diagnosed 2007-2014:
If the hemagioblastomas occur in sites with different ICD-O-3 topography codes, they are separate primaries.
Please note: Rule M4 in the Benign & Borderline Intracranial and CNS Tumors MP/H coding rules on the SEER website has been corrected to read:
Reportability--Brain and CNS: Does a case of astrogliosis meet the criteria for gliomatosis cerebri? See Discussion.
Case clinically stated to be a glioma of the brain. Pathology from resection states astrogliosis.
Anderson's Pathology defines astrogliosis as astrocytic proliferations. Gliomatosis cerebri is defined as diffuse neoplastic transformation of poorly differentiated astrocytes over a wide area; predominantly invovles hemispheric white matter.
The pathologic diagnosis for this case, astrogliosis, is not reportable to SEER. Take the definitive diagnosis for this case from the pathology report from the resection. The pathology report takes precendence over the clinical diagnosis.
Reportability--Brain and CNS: Are spinal schwannomas and neurofibromas reportable or non-reportable?
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.
Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion.
The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable.
According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Reportability--Brain and CNS: Are "spinal" schwannomas reportable if stated to be extradural, vertebral nerve sheath, or of specific vertebrae? See Discussion.
Are any of the following cases reportable?
Example 1: Clinical Diagnosis: Extradural spinal cord tumor compatible with schwannoma. What assumptions should be made about reportability if the tumor is described as being extradural? The extradural spinal cord includes epidural fat surrounding the thecal sac and exiting nerve roots. Does this mean there are not nerve roots in the extradural spinal cord?
Example 2: Final Pathologic Diagnosis: Designated "C3-4 nerve sheath tumor" excision: Morphologic and immunohistochemical findings consistent with cellular schwannoma. When stated to be a "nerve sheath tumor" does that mean peripheral nerve (C47_) involvement or nerve root (C72_) involvement?
Example 3: Final Pathologic Diagnosis: T-8 vertebral tumor resection: Schwannoma with degenerative changes (calcification, cyst formation) - ganglion and nerve are identified. There is no mention clinically or pathologically whether this tumor is "intradural" or "of the nerve root." In the absence of information about whether the location of the tumor is intradural or involving the nerve root, is it assumed that it does involve this part of the spinal cord when a specific vertebrae is removed?
Extradural schwannomas are not reportable. Neither vertebral nerve sheath nor a location of/on a specific vertebrae confirm the origin as being either extradural or intradural. Do not report a schwannoma if it cannot be determined to be "intradural" or "of the nerve root."
Reportability--Bladder: Is "low grade papillary urothelial neoplasm with no evidence of invasion" reportable to SEER?
"Neoplasm" means "new growth," not malignancy. A low grade papillary urothelial NEOPLASM with no evidence of invasion [8130/1] is not reportable to SEER. However, a low grade papillary urothelial CARCINOMA with no evidence of invasion [8130/2] is reportable.
Reportability--Appendix: Is a pathologic final diagnosis of an appendix with "well-differentiated neuroendocrine tumor (carcinoid)" reportable? See discussion.
SINQ 20130027 states that "well-differentiated neuroendocrine tumor" of the appendix is reportable (8240/3) while "carcinoid" tumors of the appendix are not reportable (8240/1). Please explain the difference between "well-differentiated neuroendocrine tumor" of the appendix and a "carcinoid" of the appendix.
Well-differentiated neuroendocrine tumor of the appendix is reportable. The difference is terminology. "Carcinoid" is listed in ICD-O-3 as a /1 for appendix making it non-reportable.
When both terms are used, ask for clarification from the pathologist. Failing that, accept the reportable terminology and report the case.
Reportability--Appendix: Is a metastatic low-grade appendiceal mucinous neoplasm reportable if the pathologist states that it is a borderline tumor of the appendix? See Discussion.
Low-grade appendiceal mucinous neoplasm; Lt ovary, cul-de-sac, omentum, and small bowel: Metastatic low-grade appendiceal mucinous neoplasm. Per pathologist this is a borderline tumor of the appendix.
Borderline tumors (other than brain and CNS) are not reportable to SEER. In the case of borderline tumors, the term "metastatic" does not automatically make them reportable. When the "metastatic deposits" are also borderline, the case is not reportable. For this case in particular, the "metastases" are actually (benign) implants and not malignant or invasive mets.
