This terminology is not specifically included in either alternate names list for myelodysplastic syndrome, NOS (9989/3) or refractory anemia with excess blasts (9983/3).

Example: Bone Marrow Biopsy, Final Diagnosis: Consistent with involvement by myelodysplastic syndrome with excess blasts-2 (MDS EB-2).

4/18/17 Right ovary and fallopian tube, salpingo-oophorectomy: mucinous borderline tumor of intestinal type with microinvasion; greatest dimension 24.5 cm. Left fallopian tube and ovary, salpingo-oophorectomy: Benign ovary with multiple benign Mullerian inclusions. Benign fallopian tube with multiple paratubal cysts. Per pathology: pT1a pNx.

Pathology report: Brain tumor, left side: Gliotic cortex and subcortical white matter with meningioangiomatosis (see Comment). Comment This specimen represents a meningioangiomatous lesion located in the leptomeninges that projects along the Virchow-Robin spaces into the underlying cortex. The surrounding brain parenchyma demonstrates reactive changes with astrogliosis and microgliosis. An intraparenchymal neoplasm is not seen. Meningioangiomatosis is a rare benign meningovascular hamartomatous condition and usually appears in young patients.

The patient is diagnosed by bilateral mammograms suspicious for malignancy in both breasts. A biopsy is done on one breast and is positive. The physician states that he will not biopsy the contralateral breast, as the patient has consented to bilateral mastectomy. The patient receives neoadjuvant chemo, follow by bilateral mastectomies. Both breasts are negative for residual cancer, stated as a complete response. Based on "suspicious for malignancy" can we accession two primaries and assume bilateral complete response?

When coding tumor grade, our pathologists have told us to code grade based on the specimen from the most definitive surgery or with the most amount of tissue, and that coding grade from the biopsy would not be appropriate even if it is a higher grade than from the surgical resection. Coding of solid tumors Instruction 5 states: If there is more than one grade, code the highest grade within the applicable system. Code the highest grade even if it is only a focus. Code grade in the following priority order using the first applicable system.

Patient had radical resection of pelvic giant cell tumor of bone in August 2012. Final diagnosis clarified that no features to suggest a frankly malignant giant cell tumor were identified.

July 2013 left upper lobe nodules were removed and found to be consistent with multifocal metastatic lung involvement with a previous pelvic giant cell tumor of bone. However, the pathology report comment specifies there are no histological high-grade features to suggest a malignancy:

While SINQ 20091087 may apply, these metastases clearly arrived in the lung by hematogenous spread. The previous SINQ note refers to a case where the implants/metastases can seed the surrounding pelvic and abdominal structures by rupture of the tumor or intraoperative tumor spillage. That type of spread is not quite the same as the current case showing tumor cells leaving the primary tumor/site and travelling through the blood to implant in the lungs.

We are seeing more use of PI-RAD categories on scans. The final impression on the scan will be PI-RADS Category 5, with no specific statement of malignancy. The scans include a blanket statement with the definitions of the PI-RADS categories as below.

PI-RADS (v2) categories:

PI-RADS 1 - Very low (clinically significant cancer is highly unlikely to be present)

PI-RADS 2 - Low (clinically significant cancer is unlikely to be present)

PI-RADS 3 - Intermediate (the presence of clinically significant cancer is equivocal)

PI-RADS 4 - High (clinically significant cancer is likely to be present)

PI-RADS 5 - Very high (clinically significant cancer is highly likely to be present)

A previous SINQ 20010094 indicates that we cannot use BI-RADS categories for breast cancer diagnosis, and SINQ 20160008 indicates we can use LI-RADS for HCC diagnosis, but those definitions are slightly different. Most often there will be a subsequent biopsy diagnosis of carcinoma, so the question is also in reference to Diagnosis Date. Can we use the date of the scans impression, which states PI-RADS category 5, as the Diagnosis Date?

Bronchial washings were negative. Four lymph nodes were biopsied and found to have metastatic poorly differentiated neuroendocrine carcinoma. The treating oncologist calls it small cell carcinoma, extensive stage, and treats patient with carboplatin and VP-16 (etoposide) The MP/H rule says to take path/cyto from a metastatic site if no pathology/cytology available from the primary site. Is the physician's statement and treatment taken into consideration here?

Patient was diagnosed with DCIS of the left breast in June 2014. The patient had a simple mastectomy with 2 axillary lymph nodes removed. The final diagnosis was intermediate to high grade ductal carcinoma in situ, predominantly micropapillary type, forming a 1.4 cm mass. No invasive carcinoma identified. Margins negative. In April 2017, the patient was found to have parietoccipital bone lesions, which were resected. The resulting diagnosis was metastatic carcinoma, morphologically consistent with breast primary " See Comment: The previous breast lesion is not available for review at the time of signout. However, the tumor is morphologically compatible with a breast primary.

SINQ 20110111 would not make this is new primary. However, it seems that rule M8 might apply. An invasive tumor following an in situ tumor more than 60 days after diagnosis is a multiple primary. See Note 2: Abstract as multiple primaries even if the medical record/physician states it is recurrence or progression of disease.
