MP/H Rules/Histology--Rectum: When not specifically mentioned as part of the histology, is the adenoma a second histologic type, or just a further physical description of the tumor? See Discussion.

Rectal tumor resection (APR) path report final dx: "mucinous carcinoma, see comment". The comment is the CAP-format tumor summary, which states "histologic type: adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma). Additional pathologic findings: adenomas - tumor arises in a tubulovillous adenoma".

If you follow the rules and only use the final dx, you would code a different histology than if you use the 'additional path findings.'

For cases diagnosed 2007 or later

Other Sites histology rule H12 applies in this case. Assign histology code 8263 [adenocarcinoma in tubulovillous adenoma].

Use information from the CAP protocol and from comments associated with the final diagnosis to code histology.

The fact that the malignancy arose in a polyp can be taken from anywhere in the medical record; not limited to the final diagnosis.

Based on the information provided for this case, the histology is adenocarcinoma with extensive mucin production (mucinous or colloid carcinoma) arising in a tubulovillous adenoma.

Histology/Behavior--Brain and CNS: How are these fields coded for an "anaplastic glioneuronal neoplasm with spongioblastic architecture"? See Discussion.

Scenario: Addendum from Mayo Clinic review, IHC and consultation made dx of "anaplastic glioneuronal neoplasm with spongioblastic architecture". The original micro states 'high grade glial neoplasm w/o characteristic features of glioblastoma multiforme in that it lacks areas of significant necrosis, no nuclear palisading nor endothelial vascular proliferation...."

The best code available according to our pathologist consultant is 9505/3 [Ganglioglioma, anaplastic]. According to our consultant, while ganglioglioma is traditionally a benign tumor, anaplastic ganglioglioma is classified as malignant by WHO (page 103), and comes as close to fitting the description of this tumor as any other term.

20081129 MP/H Rules--Breast: What histology code should be used with invasive papillary carcinoma with cribriform carcinoma component? There is also DCIS adjacent to the invasive tumor, predominant cribriform and focal papillary patterns. This is a single breast tumor. See Discussion. Registry staff is divided between 8523 and 8255.

For cases diagnosed 2007 or later:

First apply rule H9, code the invasive. To determine the code for the invasive histology, start with rule H10 and stop at rule H15. Code the histology 8503 [papillary]. Papillary (8503) and cribriform (8201) are listed in Table 1 as specific duct types, but in this case they are invasive.

Table 1 and Table 2 will be clarified in the next version of the MP/H rules.

20081017 Ambiguous terminology/Reportability--Leukemia: Is a 'suspicious peripheral blood smear' the same as a suspicious cytology? See Discussion. The final diagnosis on the path report for a peripheral blood smear is stated to be "suspicious for malignancy." The microscopic description states that the "lymphoid population raises the concern of chronic lymphocytic leukemia." Nothing further was done. Is this a reportable case? If so, should it be coded as a leukemia or a malignancy NOS?

For cases diagnosed prior to 1/1/2010:Do not accession a leukemia case based only on a "suspicious" peripheral blood smear. If a confirmed diagnosis, clinical confirmation or further information becomes available later, accession the case at that time.

For cases diagnosed 1/1/10 and later, 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/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is this a reportable clinical diagnosis?

This case is reportable because the diagnosis of precancerous melanosis was stated by a recognized medical practitioner. Precancerous melanosis meets the reportable diagnosis criteria (See 2007 SEER Manual page 1).

Assign diagnostic confirmation code 8 [clinical diagnosis only].

Set the appropriate override flag for the SEER edit.

20081051 MP/H Rules/Histology--Prostate: Path said adenocarcinoma of the prostate with an endometroid adenocarcinoma component. What histology code is used?

For cases diagnosed 2007 or later:

Assign code 8500 [duct carcinoma].

According to The World Health Organization (WHO), the term endometrioid carcinoma of the prostate is now called Prostate Duct Carcinoma.

Using Rule H11 (one type), code 8500 (duct carcinoma) for this rare type of tumor. Do not stop at Rule H10 because this is not acinar.

 2008
20081006 Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"? Record the number of tumors counted as a single primary at the time the case is abstracted. Later, if additional tumors are determined to be the same primary, update this field once. Do not update the multiplicity counter more than once. 2008

MP/H Rules--Breast: How many primaries are abstracted if a mastectomy specimen reveals two separate invasive tumors:

#1: Invasive apocrine carcinoma, poorly differentiated, 1.2cm, (9 o'clock). -Apocrine ductal carcinoma in situ (DCIS), high-grade with comedo necrosis; 2.0cm (9:30 o'clock).

#2: Invasive ductal carcinoma, well-differentiated, 1.0cm (12:30 o'clock). -Minor component of DCIS, low-grade? See Discussion.

 In the MP/H Rules, Table 1 lists apocrine as a type of intraductal carcinoma. Apocrine does not appear in Table 2, the list of specific duct carcinomas. If Apocrine is a type of ductal carcinoma, then Rule M11 would make this a single primary. If it is a single primary, what is the histology?

For cases diagnosed 2007 or later:

Using rule M11, there is one primary in the left breast. Apocrine is a specific duct carcinoma. To make this more clear, apocrine will be added to Table 2 in a future revision.

To code the histology, go to the multiple tumors module and start with rule H20. Stop at rule H29 and code the histology with the numerically higher ICD-O-3 code, 8500/3.

20081023 Histology: Must every word in the ICD-O-3 code definition appear in the diagnosis in order to assign that ICD-O-3 code? See Discussion. Is the diagnosis "Acute myeloid leukemia, M2" coded to Acute myeloid leukemia with maturation, FAB M2, NOS, (9874/3) or to Acute myeloid leukemia, NOS, (9861/3)?

For cases diagnosed prior to 1/1/2010:The general instructions for assigning histology codes are to code as precisely as possible. Acute myeloid leukemia with maturation is the definition of the FAB M2 category. A pathologist does not need to provide every word in the term associated with an ICD-O code; pathologists don't always talk that way. AML M2 is a very specific diagnosis and should be coded to 9874/3.

For cases diagnosed 1/1/10 and later, 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.

20081083 Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion. Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."

For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.

According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.

For cases diagnosed 1/1/10 and later, 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.
