No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus).

For tumors diagnosed prior to 2007:

Abstract the July 2004 diagnosis as a new endocervical primary. Abstract an invasive cancer in the same site more than two months after an in situ cancer as a new primary. Residual cervical tissue is present following a hysterectomy.

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 cases diagnosed prior to 1/1/2010:Code histology to 9984/3 [RAEB-T]. This particular MDS is refractory anemia with excess blasts in transformation. It has not yet progressed to acute myeloid leukemia.

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.

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

Use Rule PH21 to code the primary site to C778 [lymph nodes of multiple regions]. The spleen is not listed under the Primary Site(s) section in the Heme DB for follicular lymphoma. Per Rule PH21 code the primary site to multiple lymph node regions, NOS (C778) when multiple lymph node regions, as defined by ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated. The spleen is a primary site for only a few lymphomas (noted in the Heme DB). Because the spleen filters blood, it is often reactive (splenomegaly) or frankly involved with the lymphoma. That reaction or involvement, however, does not affect the primary site coding. Only the involved nodes are used in coding primary site.

SEER*Educate provides training on how to use the Heme Manual and DB.

Code histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Per the Alternate Names section in the Heme DB, B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is one of the synonyms for for DLBCL.

This case should be accessioned as one primary. Per Rule PH26, code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow. (We assumed all available physical exams, scans, and other work-up were negative for lymph node, tissue, or organ involvement.) Histology is coded to 9680/3 [Diffuse large B-cell lymphoma (DLBCL)]. Under the Alternate Names section of the Heme DB, a synonym for DLBCL is B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 85 [Metastasis] and the SEER Summary Stage 2000 field to 7 [Distant] for both types of tumor. Each kidney and each eye are staged separately in the AJCC, 6th ed., but for SEER we would abstract these diagnoses as one case and code the EOD and stage fields to distant to reflect the involvement of both eyes or both kidneys.

WHO classifies intraductal carcinoma of the prostate 8500/2. According to WHO, "the hallmark of intraductal carcinoma of the prostate is a proliferation of prostate carcinoma cells that is within and may significantly expand the native prostatic ducts and acini, with the basal cell layer at least partially preserved." Further, differentiation between intraductal carcinoma and infiltrating high-grade carcinoma of the prostate may require basal cell stains. Under Prognosis, WHO states: " intraductal carcinoma of the prostate on prostate biopsies is often associated with high-grade cancer (with a mean Gleason score of 8) ."

So while it may seem counter-intuitive, assign behavior code /2 when the diagnosis is intraductal carcinoma of the prostate.

Per Rule M2, this is a single primary because there is a single histology mentioned. The histology is coded to 9699/3 [MALT lymphoma]. Code the primary site to C509 [breast] per Rule PH24 which states to code the primary site to the organ when lymphoma is present only in an organ.

Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal, extragastric MALT lymphomas occur in multiple sites, particularly in paired sites (breast is an example).

The primary site is C482 [Peritoneum, NOS]. "Paracaval" means alongside or near the vena cava.

Code the site in which the primary tumor originated.
