12/30/11 Bladder Biopsy: Diffuse carcinoma in situ of bladder, urothelial cancer at trigone (Stage T1)

1/30/2012 Transurethral resection of the bladder was non-papillary, urothelial carcinoma, focal invasion of lamina propria, staged T1

11/10/14, 9/28/15, 9/26/16, 10/19/17 all had positive bladder cytology of urothelial carcinoma

5/16/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma

9/26/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma

10/18/16-11/7/16 Bacillus Calmette-Guerin (BCG) x3 administered into the renal collecting system via ureteral catheter

The patient has testicular cancer with bilateral lung metastases and possible liver metastasis. The left orchiectomy final diagnosis was The Summary describes a single tumor that is, Germ cell neoplasia in situ (GCNIS) is also present. Although there is mixed germ cell tumor present, the PNET component of the tumor is locally invasive extending into the epididymis, hilar soft tissues, spermatic cord, and tunica vaginalis. The mixed germ cell tumor is limited to the testis only.

We are instructed not to use to the term to code histology in the MP/H Rules General Instructions (Other Site Rules not updated for 2018), however the PNET comprises the majority of this tumor and represents the most extensive disease. Should the PNET histology be ignored in this case as its a ?

Cytology is not listed in the Priority Order for Using Documentation to Identify Histology (Histology Coding Rules) in the Head and Neck schema. Other schemas do include cytology in the hierarchy below tissue from a biopsy or resection. Cytology is often less specific than histology, so one would expect cytology to be listed below tissue in this hierarchy. Was this an oversight? Or would cytology be equivalent to histology if it provided the most specific histology for the case?

Since high grade squamous intraepithelial lesion (HGSIL) is reportable for the vulva in 2018 (per SINQ 20130185) but VIN II-III is not reportable, we need to clarify this reporting format seen in our area.

CT chest findings: 1. There is a dominant 1 cm. nodule in the left mid lung. 2. In addition, there is a new rather dominant bilobed nodule in the left lung base. 3. Distant metastases are not identified. Four months later, a doctor's note says routine follow-up visit status post Cyber Knife stereotactic body radiation therapy for synchronous early stage non-small cell carcinomas of the left upper and left lower lobes, both Stage IA. He is medically inoperable. This situation is described as a second primary tumor in AJCC8 page 438. However, by the 2018 Lung Solid Tumor rules, this would be a single primary, per rule M7. Is that correct?

For certain facilities in our area, the breast pathology reports using a CAP protocol format are formatted as follows; the Final Diagnosis will state Infiltrating carcinoma with the following features. The features list the specific tumor characteristics required in the CAP protocol formatting. The histology is always displayed in the list form and specified as Histologic type: (for example, Histologic type: Ductal carcinoma). Is this specific histology really to be ignored because it is preceded by the word type even if this is just a consequence of the pathology report formatting?

From a number of definitions reviewed, it seems unclear if it's part of the appendix or the cecum of the colon. For example: The cecum is usually located in the right iliac fossa. In the pole of the cecum, there is often the appearance of fusion of the three teniae coli around the appendix, giving rise to the tri-radiate fold (Mercedes Benz sign), but the anatomy can be variable. The most reliable landmarks of the cecum are the appendiceal orifice and ileocecal valve. The appendiceal orifice is usually an unimpressive slit, often crescentic in shape. The ileocecal valve is made up of the superior and inferior lips (usually not seen en face) and is the gateway leading into the terminal ileum. It is located on the prominent ileocecal fold encircling the cecum, between 3 and 5 cm distal to the cecal pole. (https://www.sciencedirect.com/science/article/pii/S2212097113701730)
