Assign C163. Incisura, incisura angularis, gastric angular notch, angular incisure of stomach all refer to the sharp angular depression in the lesser curvature of the stomach at the junction of the body with the pyloric canal. See Gastric angular notch in #12 on page 76 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf.  See also the SEER training website, #12 on the illustration corresponds to the angular notch, http://training.seer.cancer.gov/ugi/anatomy/stomach.html. We will correct the key for this illustration.

High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.

This case is not reportable based on the information provided. The histologic diagnosis is "metastatic histologically benign smooth muscle neoplasm." The physicians seem to agree with the histologic diagnosis, benign metastasizing leiomyoma (BML). The WHO classification and ICD-O-3 assign 8898/1 to "metastasizing leiomyoma." WHO states "This resembles a typical leiomyoma but it is found in the lungs of women with a history of typical uterine leiomyomas." A recent article states "Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy." Tamoxifen treatment is in keeping with the BML diagnosis.

Colloid cyst at the foramen of Monro is not reportable. Colloid cysts are endodermal congenital malformations and do not have an ICD-O-3 code. See the Glossary for Registrars, http://seer.cancer.gov/seertools/glossary/view/542eeea1102c1d14697ef8ab/?q=colloid

Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30.

Code high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" to sarcomatoid transitional cell carcinoma (8122/3).

Hematopoietic neoplasms that transform generally don't have 'chronic' or 'acute' as part of their preferred name. The 'chronic' and 'acute' designations are determined by the usual course of the neoplasm. Chronic neoplasms are generally slow growing while acute neoplasms grow fast and are more widespread. Not all Hematopoietic neoplasms transform. Each neoplasm that has the ability to transform has the transformations listed under the 'Transformations to' and/or 'Transformation from' sections in the Hematopoietic database.

For example, Diffuse large B-cell lymphoma (histology code 9680/3) has no histologies/neoplasms listed under 'transformations to.' This means that this neoplasm does not transform to any other neoplasm. There are multiple histologies/neoplasms listed under 'Transformations from' indicating the neoplasms listed under the Transformations from are the chronic neoplasms, and DLBCL is the acute neoplasm. If DLBCL (9680/3) occurs at the same time, within 21 days, or greater than 21 days of any of the histologies listed under 'Transformations From,' rules M8-M13 apply. If DLBCL (9680/3) occurred at the same time as a neoplasm not listed in the Transformations sections, the acute and chronic rules do not apply.

Code microwave tumor ablation as surgery. For lung, assign code 15.

This question was discussed by the technical advisory group – a small group of representatives from each standard setter which meets periodically. The group agreed on this consensus answer.

Mammary fibromatosis is not reportable. The WHO classification for breast tumors assigns mammary fibromatosis a behavior code of /1. According to WHO, mammary fibromatosis "is a locally infiltrative lesion without metastatic potential…"

Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings.
