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.

2016 Total thyroidectomy, Multifocal

-Dominant Tumor:  Right Lobe, Papillary thyroid carcinoma (8260/3)

-Tumors two through five:  Three tumors Papillary thyroid carcinoma (8260/3), and one tumor Papillary thyroid carcinoma, follicular variant (8340/3)

-An additional tumor: Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (8343/2)

In the old 2007 Multiple Primaries/Histology rules, Lung Equivalent Terms and Definitions section, oat cell carcinoma (8042) was listed as one of the obsolete terms that was no longer recognized for small cell carcinoma.  That note is not in the current 2018 Solid Tumor Manual lung chapter, and ICDO-3.2 lists oat cell carcinoma as the preferred term for code 8042/3.  Would rule H4, Note 2 apply -- only one histology present, if not listed in Table 3 use ICD-O and all updates, to code oat cell carcinoma as 8042/3?

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.

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.

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? 

History provided by the oncologist

Right neck mass since 2019; 04/07/20, initial biopsy p16-negative SCC, delay of treatment due to patient preference, agreed to biopsy of tonsil and work-up August 2022; right tonsil biopsy: p16-positive, G2 SCC, nodal mass at that time >6 cm with extensive extranodal extension, Stage III (cT2, cN3, cM0, p16-positive); based on this history, was staged as a tonsil primary and p16-positive.

Patient details

1. March 2020, CT neck and chest revealed a 0.5 x 2.7 x 2.3 cm low-density necrotic nodal mass at right neck level 2 suspicious for metastatic disease.  There was a slight asymmetric increased size of the right palatine tonsil.  There are a few sub-4 mm pulmonary nodules which are nonspecific.

2.  April 7, 2020, FNA of right neck mass with pathology revealed p16-negative SCC   

3.  April 20, 2020, PET/CT revealed 3 x 2 cm right-sided level 2 node with FDG avidity  

4.  May 5, 2020, flexible laryngoscopy showed no obvious primary lesion   

5.  May 2020, after evaluation by a medical oncology, patient declined any treatment  

6.  June 17, 2022, return visit in medical oncology after PET/CT demonstrates significant progression in the neck; patient definitively declines chemo, but would like surgical opinion.  Now has more rapidly progressive disease with skin breakdown and weeping from malignant lesion right neck.  

7.  June 22, 2022, radiation oncology consultation   

8.  July 15, 2022, tonsil biopsy: Invasive squamous cell carcinoma, moderately differentiated with LVI, p16-positive  

9.  Patient now agreeing to treatment with radiation: Tooth extractions 8/30/2022, radiation planning 9/14/2022  

10.  Patient consulted with cancer specialist who explained surgery is not recommended given level of extranodal extension and risk of seventh cranial nerve paralysis and fistula formation with surgical excision and who recommended chemoradiation

11.  September 9, 2022, patient presented for radiation CT simulation/treatment planning and informs treatment team. Patient declined/refuses concurrent chemotherapy despite recommendations from two cancer institutions.

A 17 year old exchange student was brought into the hospital with appendicitis.  The patient had an appendectomy; there was no follow up treatment.  5/27/2006 pathology report of vermiform appendix:  Adenocarcinoid appendix <5 mm tumor limited to appendix.

The patient has no record in Lexis Nexus and no social security number.  The address is a post office box; additionally, the patient’s birthplace is Switzerland and is lost to follow up.

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?

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.
