Report Question ID Question Discussion Answer Year
20081076 Reportability--Lung: Is carcinoid tumorlet of the lung a reportable disease? See Discussion. The literature on this is rather ambiguous as to whether these tumorlets (defined as <0.5 cm) are benign, such as atypical hyperplasia, or actual carcinoid tumors. Carcinoid tumorlets are not reportable. The histology can be similar to typical carcinoids; however, they are <5 mm in diameter and are benign/nonreportable. 2008
20000845 Primary Site: What code should be used to represent the site for an "extraovarian" papillary serous adenocarcinoma located in the "rectal muscle sheath"? See discussion. The location of the tumor in the rectus muscle sheath is unusual and suggests an origin within a preexisting mullerian. Code the Primary Site field to C49.4 [connective, subcutaneous and other soft tissues of the abdomen]. 2000
20100002 Reportability/Histology--Colon: Is a colon tumor reportable if the pathology report final diagnosis is high grade dysplasia but CAP protocol histologic type designation is adenocarcinoma in situ? See Discussion. The microscopic description and the final diagnosis on the pathology report indicate the tumor is a large tubulovillous adenoma of the cecum with focal surface high grade dysplasia. The CAP protocol histologic type designation is adenocarcinoma in situ and pT designation is pTis. Which has priority? Is the case reportable?

The case is reportable because carcinoma in situ is stated. Carcinoma in situ has higher priority than severe dysplasia or high grade dysplasia.

Per AJCC 6th edition colon chapter, the terms "high grade dysplasia" or "severe dysplasia" may be synonymous with carcinoma in situ. Because the pathologist gave carcinoma in situ information within the CAP, (s)he is apparently defining the dysplasia as in situ carcinoma.

20120055 Surgery of Primary Site--Kidney, renal pelvis: How do you code a laparoscopic renal mass core biopsy followed by cryoablation of the tumor? See Discussion. The note under the local tumor destruction codes states "No specimen sent to pathology from this surgical event 10-15." The patient had a pathologic specimen submitted from his core biopsy, but this was not a tumor excision or excisional biopsy [codes 20, 26-27]. Is the correct surgery code 13 [cryosurgery] because the tumor was only ablated and not excised, or surgery code 23 [any combination of 20 or 26-27 with cryosurgery] because a pathology specimen was submitted? Code for Surgery of Primary Site to 13 [Cryosurgery]. While the core biopsy provided a pathology specimen, it is not coded as surgery of the primary site. 2012
20051006 Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Thyroid: How is histology coded for the tumor(s) that exist when the thyroidectomy addendum diagnosis is "Morphologic and IHC evaluations reveal two tumors: papillary thyroid carcinoma and squamous cell carcinoma." See Discussion. The original final diagnosis after a thyroidectomy is "papillary carcinoma of the thyroid with an adjacent invasive squamous cell carcinoma, moderately differentiated." Per the additional addendum comment: "The findings can be interpreted in one of 2 different ways. Either there is a collision tumor of papillary thyroid and squamous cell carcinoma (with the squamous cell ca originating at a site other than the thyroid gland.) Or, less likely, there is a malignant squamous differentiation in the papillary thyroid carcinoma." A university hospital consultation report states the diagnosis as: "Spindle cell squamous cell carcinoma arising in association and from papillary carcinoma, predominantly tall cell variant..." Is this 2 thyroid primaries: 8344/3 [papillary carcinoma, tall cell] and 8074/3 [squamous cell carcinoma, spindle cell]?

For tumors diagnosed prior to 2007:

Our pathologist consultant agrees with the consultant's diagnosis. Therefore, abstract this as one primary of the thyroid. Code the histology as 8344 [Papillary tall cell]. This is the most appropriate histology code available for this complex case.

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.

20021173 Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion. The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section.

For tumors diagnosed prior to 2007:

Code the Histology field to 8070 [squamous cell carcinoma].

The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.

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.

20091084 Primary site--Colon: How do you determine the correct subsite when there is conflicting information in different reports? Are there priority rules for coding subsite for sites other than Head and Neck? See Discussion. The path report for a hemicolectomy says, " Specimen: left colon..." and the microscopic says, "...received in formalin designated left colon..." The Operative procedure report says, "Postoperative diagnosis - splenic flexure tumor." The text of this report says, "Mobilizing the splenic flexure mass was incredibly difficult..." and then goes on to describe exactly how and where it was resected. The discharge summary says adenosquamous carcinoma of the splenic flexure. SINQ20051010 says to use the pathology report first, but this was written before the new MP/H rules.

Use the operative report information to code primary site in this case. It is more accurate.

The operative report is usually a better source of location information compared to the pathology report. The pathologist can only reiterate the location as it was reported to him/her.

The 2007 SEER manual states "Unless otherwise instructed, use all available information to code the site," page 69.

20061008 Histology (Pre-2007)--Corpus uteri: How is a polyp with "endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma" coded? See Discussion. The path report for the TAH stated the endometrium contained an endometrial polyp measuring 6x3x3cm. Within the polyp there was endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma. There is no myometrial invasion by the tumor. (The Endometrial bx before surgery was positive for Malignant Mixed Mullerian tumor.)

For tumors diagnosed prior to 2007:

Assign code 8980 [Carcinosarcoma, NOS]. According to the WHO Classification of tumors, Malignant mullerian mixed tumor is a synonym for carcinosarcoma and carcinosarcoma is now the preferred terminology rather than malignant mixed Mullerian tumor.

Carcinosarcoma has both malignant epithelial and mesenchymal components. The epithelial component is usually glandular (adenocarcinoma in this case). The mesenchymal component is usually sarcoma (as in this case).

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.

20021108 Histology (Pre-2007)/Grade, Differentiation: What code is used to represent the histology of "well differentiated low grade lipoma-like liposarcoma (atypical lipoma)"? See discussion. The pathologic microscopic description states, "Well differentiated lipoma-like liposarcoma, sometimes termed atypical lipoma. This tumor will behave in a low grade malignant fashion. Slow growing recurrences can be expected. Metastatic disease is very rare unless the tumor dedifferentiates."

For tumors diagnosed prior to 2007:

Code the Histology field to 8851/3 [Liposarcoma, well differentiated] and the Grade to 1 [Well differentiated]. This histology is reportable to SEER.

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.

20041047 Multiple primaries (Pre-2007)/EOD-Extension--Fallopian Tube: How many primaries are coded when endometrioid adenocarcinoma involves bilateral fallopian tubes? See Discussion. The pathologist states "because of the intimate association with the luminal line of the fallopian tube it is felt that this represents synchronous primaries rather than mets." The SEER Code Manual only lists ovary, retinoblastomas, and Wilms Tumors under the bilateral code stated to be a single primary.

For tumors diagnosed prior to 2007:

Complete two abstracts, one for left fallopian tube and one for right fallopian tube. This case has been determined to be two primaries by the pathologist. Bilateral involvement of paired sites (other than ovary, retinoblastoma and Wilms tumor) with the same histology within two months requires a determination of whether there are one or two primaries. The pathologist in the case above has made this determination.

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.
