20130125 Reportability--Heme & Lymphoid Neoplasms: Is self-healing Langerhans cell histiocytosis (LCH) of the skin reportable?

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

This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.

The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

MP/H Rules/Multiple primaries--Colon: Does rule M7 apply here (A frank malignant or in situ adenocarcinoma and an in situ or malignant tumor in a polyp are a single primary)? Can the frank malignant adenocarcinoma be any specific type of adenocarcinoma for this rule to apply?

A patient has 2 synchronous tumors in the ascending colon. The first is grade 3 adenocarcinoma with signet ring differentiation and focal mucinous features (8255/3). The second is grade 2-3 adenocarcinoma in a tubulovillous adenoma (8263/3).

M7 applies to this case. The frank adenocarcinoma can be a specific type of adenocarcinoma.

20051096 Primary Site--Peritoneum: During a second look staging lap following a diagnosis of serous carcinoma of the left ovary, did the physician correctly indicate a new peritoneum, NOS primary for disease described as an endometrioid adenocarcinoma in a "paracaval cyst" that appears to have arisen in endometriosis?

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

Code the site in which the primary tumor originated.

20021069 Histology (Pre-2007)--Breast: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"?

For tumors diagnosed prior to 2007:

Code the Histology field to 8520 [Lobular carcinoma].

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.

20110062 Histology--Heme & Lymphoid Neoplasms: Is diffuse large B-cell lymphoma, germinal cell type coded to diffuse large B-cell lymphoma?

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

Per Rule PH30, use the Heme DB, determine the histology when rules PH1-PH29 do not apply. Code diffuse large B-cell lymphoma, germinal cell type to 9680/3 [diffuse large B-cell lymphoma (DLBCL)][9680/3]. Under the Alternate Names section of the Heme DB, these two terms are synonyms that share the same histology code.

Ambiguous terminology: Does the phrase "considered to be" represent ambiguous terminology when modifying a reportable term?

A tumor considered to be malignant is reportable. "Considered to be" is an UNambiguous term.

Reportability--Breast: Is this reportable as 8520/2?

Final Diagnosis: Atypical Lobular Hyperplasia (ALH/LCIS). We are seeing this diagnosis quite often.

 ALH/LCIS is reportable. LCIS (lobular carcinoma in situ) is a reportable neoplasm. When LCIS is stated as the final diagnosis, report the case. 2014
20021193 Grade, Differentiation--Breast: Does SEER agree with our pathologist who contends that "by convention lobular carcinoma is considered to be grade 2"? No. SEER does not have a default grade code for lobular carcinoma. Code the grade as stated in the pathology report. If no grade is stated, code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable]. 2002
20100074 Laterality--Melanoma: For a melanoma case, does the term "mid" imply that the tumor is in the midline when the site is the skin of back (trunk)? Yes. When the location is described as mid-back or mid-chest with no indication of left or right, assign laterality code 5 [midline]. 2010
20051113 Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?

For tumors diagnosed prior to 2007:

Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.

Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."

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.
