Reportability/Histology: Would a histology reading "Well-differentiated neuroendocrine neoplasm" of the appendix be reportable? Since the word "tumor NOS" and "neoplasm NOS" both code to 8000, I would assume they would be interchangeable but just wanted to verify.
According to SINQ 20130027 & 20140002 a "Well-differentiated neuroendocrine tumor" of the appendix IS reportable.
"Well-differentiated neuroendocrine neoplasm" of the appendix is reportable. According to the WHO classification of Digestive System Tumors, "Well-differentiated neuroendocrine neoplasm" of the appendix is synonymous with NET. WHO states on page 13 "The term 'neuroendocrine neoplasm' can be used synonymously with 'neuroendocrine tumor.'"
Neuroendocrine "tumor," or NET G1, is listed in the WHO classification as one of the malignant neoplasms of the appendix.
Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.
FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma
Report this case as a basal cell carcinoma, noninvasive, of the nasal cavity, based on the information provided.
The polyp was removed from the nasal cavity (C300) which is a reportable site for basal cell carcinoma.
Primary Site--Testis: What is the prmary site for a 38 y/o male diagnosed with testicular cancer in a formerly undescended testis that was treated with orchiopexy at age 10-11? See discussion.
Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis?
Code the primary site C621 (descended testis). The primary site of this neoplasm is a scrotal (descended) testis. The history of orchiopexy can be noted in a text field, but does not change the primary site in this case.
Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion.
Please confirm correct coding for grade for papillary urothelial carcinoma of the bladder/renal pelvis and urothelial carcinoma of the bladder/renal pelvis. SEER Manual 2014 and 2015 state: "Do not use these tables to code grade for any other groups including WHO (CNS tumors), WHO/ISUP (bladder, renal pelvis), or FIGO (female gynecologic sites) grades." They also state "In transitional cell carcinoma for bladder, the terminology high grade TCC and low grade TCC are coded in the two-grade system" in the Grade section. These statements are not included in SEER Manuals prior to 2014.
Use the grade stated on the pathology report to code grade/differentiation for bladder and renal pelvis field unless the grade is stated to be WHO/ISUP grade.
Reportability/Primary site--Skin: Is a basal cell carcinoma of the lip "ever" reportable and if so, what would need to be documented or seen? See discussion.
There is a 1988 case that hit the SEER edits for other reasons but not because of that site/histo combination (C000 and 8090/3); however, there is no text.
Per a Dataminer query, there are 42 cases in the state database with C000-C009 and 8090. On review, a few did have a mention of the word "upper lip/mucosa" in the PE text or OP findings (not path because a lot of these are removed in the MD office and we don't see the path report). Other times, there is no mention but the abstractor used the C00 codes instead of C44 so the cases get through.
SINQ #20031110 addresses this in relation to C000, Lip, NOS but we want to know if this answer meant you would never report a basal carcinoma lip case period (even if there is a mention of mucosa or any mention of mucosa in the path report). Are there any exceptions?
It seems if you would never report a basal lip carcinoma, then SEER would block those cases from being reported/submitted and the wording would be stronger in the SEER manual.
Right now the reportability only addresses if someone codes C44 but if someone decides to use C00 codes then it is allowed. Under Primary Site, there is even a listing under 12 for "absence of any additional information" and lists "Colored / lipstick portion of upper lip" as code C000.
BCC of lip C00_ is rare and requires a statement that the tumor is on the vermilion border (rather than skin) to be coded C00_ and to be reported. Our expert pathologist consultant refers to an article in the Am Acad Dermatol 2004; 50(3): 384-387.
Reportability--Skin: Is low grade trichoblastic carcinoma, with a small focus of high grade carcinoma of the scalp reportable? See discussion.
Pathology report states: the individual nodules of trichoblastic cells resemble those seen in trichoblastoma, but the lesion is very poorly circumscribed with an infiltrative border that extends into the subcutis. the lesion may behave in a locally aggressive fashion, and should be completely removed. High grade trichoblastic carcinomas can metastasize.
Trichoblastic carcinoma of the skin is not reportable. The WHO classification lists trichoblastic carcinoma as a synonym for basal cell carcinoma, 8090/3. Basal cell carcinoma of the skin is not reportable. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf.
MP/H/Histology--Lung: Would you code a lung primary of "non-small cell carcinoma with neuroendocrine differentiation" to non-small cell carcinoma (8046/3) or carcinoma with neuroendocrine differentiation (8574/3)? See discussion.
The pathology report states "Right mediastinal mass: poorly differentiated non-small cell carcinoma with neuroendocrine differentiation." This is the only histologic confirmation of this lung primary that is collected.
Code carcinoma with neuroendocrine differentiation (8574/3). MP/H rule H7 applies: code the higher ICD-O-3 code. There is non-small cell lung carcinoma (8046/3) and a carcinoma, NOS with neuroendocrine differentiation present (8574/3).
Reportability--Appendix: Is the appendix the primary site for a low grade mucinous appendiceal neoplasm (LAMN) with diffuse peritoneal dissemination? See discussion.
Patient had an appendectomy revealing a low grade mucinous appendiceal neoplasm (LAMN) with diffuse peritoneal dissemination. Patient now with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC), which revealed metastatic disease in the abdomen, omentum, pelvic peritoneum, peri-cecal, and gallbladder.
For cases diagnosed prior to 1/1/2022
Low-grade appendiceal mucinous neoplasm (LAMN) is not reportable, even when it spreads within the peritoneal cavity, according to our expert pathologist consultant. Peritoneal spread of this /1 neoplasm does not indicate malignancy. It is still /1 when there is spread of LAMN in the peritoneal cavity.
Reportability: Is penile intraepithelial neoplasia, differentiated type, reportable? See discussion.
Foreskin circumcision shows: Penile intraepithelial neoplasia, differentiated type (differentiated PeIN). If reportable, how would the histology and behavior be coded? Is this behavior /2?
For cases diagnosed 2018 and later
Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2).
Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2).
