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)?

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?

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.

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.

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.

In the September 2021 Urinary Sites Solid Tumor Rules update, the term configuration was removed from the “DO NOT CODE histology when described as” list. However, it was not added as a term that can be used to code the more specific histology for urinary tumors.

Can configuration be used to code the more specific histology 8130 (papillary urothelial carcinoma) when the diagnosis is urothelial carcinoma, tumor configuration: papillary?

The left thyroid lobectomy/isthmusectomy returned a diagnosis of sclerosing mucoepidermoid carcinoma with eosinophina, 6.5 cm, replacing nearly the entire left lobe of the thyroid.

The patient has a completion thyroidectomy of the right lobe and returned the diagnosis of papillary thyroid carcinoma, 0.5 mm, in maximum dimension.

The endocrinologist describes it as "co-exsisting" and states the tumor is iodine non-avid.

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? 

The pathology report states this is a rare entity described in case reports and not incorporated into the WHO classification of tumors. A subsequent endocrinology note stated “papillary tumor, benign by path; tumor was not an adenoma; based on one Mayo study, the recurrence risk is low.”

Patient has a remote history of a right thalamic mass status-post two resections; reported as malignant oligodendroglioma (pathology not received) and chemo/radiation therapy, who recently presented with persistent headaches. Imaging revealed a 3.4 cm heterogeneous lobulated right thalamic mass with coarse calcifications and a probable cystic component.

Pathologist indicates the histologic and immunophenotypic features of this neoplasm are that of relatively circumscribed neuroepithelial tumor without high grade features (mitotic activity, microvascular proliferation, necrosis). Molecularly this neoplasm is characterized by a PATZ1-EWSR1 fusion, which has recently been proposed to be a distinct neuroepithelial tumor entity with a broad histological spectrum.
