Colloid cyst at the foramen of Monro is not reportable. Colloid cysts are endodermal congenital malformations and do not have an ICD-O-3 code. See the Glossary for Registrars, http://seer.cancer.gov/seertools/glossary/view/542eeea1102c1d14697ef8ab/?q=colloid

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

Code the histology to 9591/3 [B-cell lymphoma, NOS].

After searching the Heme DB for the term , no B-cell leukemia/lymphoma NOS code is found. However, the diagnosis of B-cell lymphoblastic leukemia/lymphoma is found. This case scenario does not specify that this is a lymphoblastic leukemia/lymphoma; therefore, the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied.

A subsequent search of the Heme DB for the term returns "Non-Hodgkin lymphoma, NOS" [9591/3]. Under the Alternative Names section of the Heme DB, B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Therefore, the B-cell lymphoma NOS code [9591/3] is the most appropriate histology code to use for this case.

This will be added to the next revision of the Heme DB and Manual.

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

Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.

Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.

For cases diagnosed 2007 or later:

Assign code 8140 [adenocarcinoma, NOS]. See the MP/H rules for Other Sites, histology coding rule H10.

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

Code the primary site to the involved lymph nodes [C770-C779]. Per Rule PH 8, it indicates you are to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. Note 2 further states that the bone marrow may or may not be involved. If the bone marrow is involved, code this information in the CS Extension field.

Per the Abstractor Notes section in the Heme DB, this is a systemic disease with widespread lymph node involvement as well as involvement of the peripheral blood. In addition, systemic involvement of extranodal sites (including lung) are often involved.

For cases diagnosed 2007 or later, assign histology code 9505/1 [Ganglioglioma, NOS].

According to our pathologist consultant, low grade neuroglial tumor of the fourth ventricle correlates best to the "rosette-forming glioneuronal tumor of the 4th ventricle" which is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Code vascular encasement of the celiac artery to CS extension code 68 [tumor is inseparable from the celiac axis].

This celiac axis is a small (1cm) area of branching arteries. The celiac artery branches into hepatic, gastric, and splenic at the axis. Dissecting tumor out from around the celiac axis is very tricky and usually encasement by tumor is a sign of inoperability.
