IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries.

We were previously told that papillary microcarcinoma is coded to 8260 (papillary thyroid carcinoma) and not papillary microcarcinoma (8341). That is an area of confusion. 

A January 2022 endometrium biopsy and curettage both show final diagnosis of “mild cytologic atypia and glandular crowding, at most endometrioid intraepithelial neoplasia.”  Any subsequent surgery path is unlikely to provide clarification.

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 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?

There is an ICD-O histology code for papillary carcinoma, columnar cell (8344/3) as well as papillary carcinoma, encapsulated (8343/3). Per Rule H13, the terms “with features of” may be used to identify a subtype.

Considering these two subtypes, and knowing there is no specific histology code for this combination, is the first rule that applies H17 (code the numerically higher histology code)?

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.

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.

2022 case: Surgical Pathology Report-spinal cord tumor, biopsies: ALK-positive neoplasm most consistent with ALK-positive histiocytosis.

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.
