The Schema ID for C051 (soft palate, NOS) and C052 (uvula) is Oropharynx (either 00100 or 00111 depending on p16). The Solid Tumor Rules Manual includes these site codes are under Table 4: Tumors of Oral Cavity and Mobile Tongue site group for histology coding. We are aware of the notes that allow coding of 8086 for keratinizing SCC, HPV-negative for sites listed in Table 5 only. However, it seems like C051 and C052 were incorrectly omitted from Table 5 (mis-categorized under Table 4). Can we code 8085 for 8086 for C051 or C052 based on p16/HPV status?

Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient.

SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021.

With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently.

Lutathera is a radioconjugate consisting of the tyrosine-containing somatostatin analog Tyr3-octreotate (TATE) conjugated with the bifunctional, macrocyclic chelating agent tetra-azacyclododecanetetra-acetic acid (DOTA) and radiolabeled with the beta-emitting radioisotope lutetium Lu 177 with potential antineoplastic activities.

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.

Acinar predominant adenocarcinoma measures at least 12 mm and involves wedge biopsy margins, while the lepidic predominant adenocarcinoma measures 11 mm and does not involve the margins of that separate specimen. Pathologist also notes, “CT findings of diffuse coarse reticular nodular opacity, these findings may represent pneumonic type adenocarcinoma/diffuse pulmonary involvement or intrapulmonary metastasis.  Both of these scenarios have the corresponding stages of pT4 (if thought to be ipsilateral) or M1a (if thought to also involve the contralateral lobe).”

Patient declined any further treatment and transitioned to hospice before expiring less than 1 month after wedge biopsies.

It is unclear if Rule M6 would apply to these two specimens with different subtypes since this scenario is not specifically addressed in the M rule definitions.

In the WHO Classification of Female Genital Tumors, 5th edition, for the uterine cervix squamous intraepithelial lesions, there is related terminology for high grade squamous intraepithelial lesion HSIL (CIN3) 8077/2 and it is severe squamous dysplasia; squamous cell in situ. However, in the online WHO Classification of Digestive System Tumors, 5th edition, there is no related terminology for esophageal high-grade squamous dysplasia, 8077/2. Can you collect cases of severe dysplasia the same as cases of high grade dysplasia? 

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.
