Category 4: Lesions that do not have the characteristic morphologies of breast cancer but have a definite probability of being malignant.

Category 5: lesions have a high probability of being cancer.

Example: An MRI Spine showed a large expansile mass arising from the sella turcica and extending into the suprasellar cistern, but the radiologist only noted: The leading differential considerations include pituitary macroadenoma or a large suprasellar base meningioma. The patient was subsequently pathologically diagnosed with a pituitary adenoma. It is unclear if the diagnosis date should be coded to the MRI date.

There are two existing SINQ questions regarding the term consider. SINQ 20061094 confirms a diagnosis that is considered to be is reportable because it is unambiguous, but SINQ 20081033 states the phrase malignancy is highly considered is not a reportable ambiguous term.

How should we interpret differential considerations? If differential considerations is equivalent to a differential diagnosis, then this patient was clinically diagnosed on imaging. However, if differential considerations is not reportable, then there was no diagnosis prior to the resection.

The radiologist noted the mass was most compatible with a chondroid lesion, which is not reportable on its own, but can the subsequent term be used to accession this as reportable if only one malignant etiology is provided by the radiologist? Or does the statement imply that this is only one of several possible etiologies?

Is this histologic terminology synonymous with 8071/2 Differentiated-type vulvar intraepithelial neoplasia?

Per the 7/20/2018 updates to the 2018 ICD-O-3 Histology list, the reportability flag was changed from N to Y for Differentiated-type vulvar intraepithelial neoplasia as well as Differentiated penile intraepithelial neoplasia, both 8071/2. It appears that both SINQ 20180020 and the second half of SINQ 20160069 are no longer valid and should be deleted.

The note explains: The International Society for the Study of Vulvovaginal Disease (ISSVD) in 2004 revised its classification of VIN by eliminating VIN 1 and combining VIN 2 and VIN 3 into a single category (see table below). Classification of VIN (usual type) ISSVD [International Society for the Study of Vulvovaginal Disease]1986 classification 2004 classification VIN 1 VIN2 VIN3 VIN Note: VIN 2 and VIN 3 combined into single [non-graded] category, VIN Reference: Scurry J and Wilkinson EJ.  Review of terminology of precursors of vulvar squamous cell carcinoma. Journal of lower genital tract disease, 2006; 10(3):  161-169

In comparison to SINQ 20180022, this case does not mention VIN III anywhere in the final diagnosis. Is any mention of HGSIL in the final diagnosis reportable, even if it is qualified with a non-reportable term in parenthesis or CAP protocol?

The term "non-invasive follicular thyroid neoplasm with papillary-like nuclear features" is now being used, instead of the previous classification of an encapsulated malignant thyroid tumor. Recent evidence supports a very minimal risk of aggressive behavior for these tumors, and pathologists in our area are no longer classifying these as malignant in the final diagnosis.

The patient is a 34 year old who presented with testicular pain radiating into the abdomen approximately 1 month before orchiectomy in 2018. CT abdomen/pelvis: Multiple focal sclerotic bone lesions. Given the lack of change from July 2014, these are likely benign bone islands. No adenopathy mentioned. He has no prior history of germ cell tumor nor any surgery for any tumor/cancer before this. Pathology: Testis, left, radical orchiectomy: - Demarcated scar tissue (1.3 cm), with atrophic seminiferous tubules and cortical bone consistent with burnt-out germ cell tumor. No evidence of germ cell neoplasia in situ (GCNIS). - Margins are unremarkable.

Mature teratoma is listed as a benign neoplasm (9080/0) in the ICD-O-3. SINQ 20120085 references a NAACCR Webinar that indicated pure mature teratomas of the testis in adults are reportable. We are not aware of any further documentation of this change in reportability. When did mature teratomas of the testis for adults become reportable? What is the defined age range for "adult"? The original SINQ question above lists the 2012 SEER Manual as a Reference, however, no clarification or mention of this change in reportability was found in that manual.
