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

This is a reportable diagnosis of chronic lymphocytic leukemia [9823/3]. The physician is using the terms "characteristic of" in the same manner as he/she would use the terms "diagnostic of."

This case fits with the usual diagnosis of CLL. The peripheral blood is diagnostic for leukemias. There was a specific leukemia noted, B-cell chronic lymphocytic leukemia. CLL (B-cell is the phenotype) is usually diagnosed incidentally by a peripheral smear because it is asymptomatic. However, we recommend looking for further work-up, such as a bone marrow biopsy.

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

As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.

A correction to page C-595 of the 2004 SEER manual will be included in the next errata.

Carcinoma cuniculatum of the hard palate is reportable. Code to SCC, NOS (8070/3). Use text fields to record the details.

While WHO recognizes carcinoma cuniculatum to be a new variant of oral cancer, it has not proposed a new ICD-O code for this neoplasm.

The best code available for this situation is 8153/3 [Gastrinoma, malignant].

Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.

For tumors diagnosed prior to 2007:

For cases diagnosed on or after 1/1/2001: Code the Histology field to 8575/3 [metaplastic carcinoma]. Sarcomatoid is not coded as sarcoma.

The terms metaplastic carcinoma, squamous cell carcinoma and intraductal carcinoma are used, but only the metaplastic and squamous cell carcinomas are invasive. Metaplastic, loosely defined, means tissue that is not normal.

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.

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 laterality as bilateral, code the greatest extension from either side in CS extension.

Code CS Mets at diagnosis 00 [None] UNLESS true distant metastases were identified.

For cases diagnosed 1/1/04-12/31/06, code histology to 8524 [Lobular mixed with other types of carcinoma]. Assuming there is no mention of in situ, Histology Coding Rule 3 applies: Use a mixed histology code if one exists

For cases diagnosed 2007-2014, 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.

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.CS Site Specific Factors 1 through 6 for head and neck sites may be coded using either clinical or pathologic information.
