There is an ICD-O histology code for papillary carcinoma, tall cell (8344/3) as well as papillary carcinoma, oxyphilic cell (8342/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context.

The term “variant” can be used for the Other Sites (non-updated STR sites) primaries when the ICD-O-3.2 (or ICD-O-3 for older cases) includes the term “variant” in the histology name. The MPH General Instructions did not include the term “variant” as a term that can be used to code histology.

There is an ICD-O histology code for follicular carcinoma, minimally invasive (8335/3) as well as follicular carcinoma, oxyphilic cell (8290/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context.

The Multiple Primaries/Histology General Instructions and histology rules do not include the term “variant” as a term that can be used to code a further histologic subtype. The term “variant” can be used for the Other Sites (non-updated STR sites) when the ICD-O-3.2 (or ICD-O-3 for older cases) provides the term “variant” in the histology name.

Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site.

Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery?

Patient had a partial nephrectomy with final diagnosis of papillary renal neoplasm with reverse polarity.  Diagnosis comment states: Papillary renal neoplasm with reverse polarity is currently considered to be a histologic variant of papillary renal cell carcinoma; however, recent studies suggest that it has a very indolent clinical behavior.

11/16/20: Patient diagnosed with endometrial cancer on by MRI of the pelvis; 11.5 cm uterine mass consistent with cancer with no lymphadenopathy.

1/6/21: Patient had a total abdominal hysterectomy/bilateral salpingo-oophorectomy and pelvic lymph node dissection. Operative report stated patient had mildly enlarged bilateral pelvic nodes.

Path report: Endometrioid adenocarcinoma with invasion of the serosa. Five bilateral pelvic nodes were sampled and negative. Originally, staging had patient as node negative.

1/22/21: Patient had post op imaging done that showed metastatic retroperitoneal, aortocaval, and possibly left iliac lymph nodes. Physician changed staging to include the lymph node involvement.

For example:

-ultrasound of the right eye: consistent with a nevoma/melanoma; we could not find any indication that nevoma is a reportable term

-bladder biopsy pathology report:  severe urothelial dysplasia/carcinoma in situ (CIS)

As a central registry, we receive some limited information cases like this where there is no record of treatment or possibility to follow-back to physicians for clarification, so we want to make sure we are reporting them correctly.

Patient has a diagnosis of myeloid sarcoma presenting as multiple erythematous papules and nodules on back, chest, right arm & shoulder. Oncologist did not mention any evidence or suspicion of an associated AML diagnosis.

HemeRetic schema EOD Primary Tumor Note 1 states that myeloid sarcoma can be coded as localized (code 100) or systemic (code 700). It is not clear what would qualify as systemic disease for myeloid sarcoma.

Example:  Patient scheduled for left nephrectomy on 3/10/20 due to left renal papillary renal cell carcinoma diagnosed on 2/11/20 via needle core biopsy. Abstract indicated surgery was cancelled due to the pandemic. Abstract also indicated the surgery was not rescheduled.
