5/15/17 Duodenal bulb, biopsy: Fragments of duodenal mucosa with well differentiated neuroendocrine tumor (carcinoid), extending to the edge of specimen and peptic duodenitis in the submitted tissue. No significant intraepithelial lymphocytosis.

In comparison to SINQ 20180022, this case does not mention VIN III anywhere in the final diagnosis. Is any mention of HGSIL in the final diagnosis reportable, even if it is qualified with a non-reportable term in parenthesis or CAP protocol?

Patient presented with hoarseness and palpable neck mass. No palpable adenopathy (per hospital abstract).

02/19/16 Thyroid Ultrasound: Right thyroid lobe with mass, 63X35X44XMM (per hospital abstract).

06/01/16 Right thyroid lobectomy, radical resection right laryngeal tumor (per hospital abstract).

06/01/16 Operative Procedure: Tumor was invading laryngeal soft tissue and cartilage anteriorly and to the right. There may be a small amount of residual tumor invading cartilage although this was not clear (per hospital abstract).

GROSS DESCRIPTION: 1. The specimen is received fresh for intraoperative consultation, labeled with the patient's name and "right thyroid mass." It consists of a 3.0 x 2.2 x 2.0 cm irregular, ragged fragment of tan-red, firm, rubbery soft tissue. The specimen is serially sectioned to reveal a tan-red, gritty cut surface with focal fleshy areas. A touch prep is performed. A representative section is submitted for frozen section analysis in 1FSA. A portion of tissue is submitted for flow cytometry with the accession number MSO-16-1786. The remaining specimen is entirely submitted in 4 additional cassettes (1B-1E). 2. The specimen is received in formalin and is labeled "right thyroid lobe." It consists of a thyroid lobe measuring 4.3 x 4.0 x 1.3 cm and weighing 10.0 g. The external surface is covered by a thin fibrous capsule with a focal area of roughening on the posterior surface. The lobe is inked black posterior, blue anterior and orange isthmus margin. Serial sectioning reveals a red-brown and beefy parenchyma. A definitive nodule is not grossly identified. The entire specimen is serially submitted from superior to inferior in 9 cassettes. 3. The specimen is received in formalin, labeled with the patient's name and "right neck/laryngeal mass." It consists of an irregular, focally nodular red-tan mass measuring 7.0 x 5.5 x 4.0 cm and weighing 54 g. The convex portion of the specimen is mostly encapsulated with focal adherent red-brown striated skeletal muscle. The concave portion of the specimen is focally ragged and disrupted. The convex portion of the specimen is inked black and the concave portion is inked blue. The specimen is serially sectioned to reveal a white-grey to red, granular, gritty cut surface with focal fleshy areas. Representative sections are submitted in 12 cassettes.

Final DX DIAGNOSIS: 1. Right thyroid mass excision Plasma cell tumor /plasmacytoma 3 cm. Tumor cells are positive for kappa and negative for lambda immunostains. Recommend correlation with flow cytometry MSO-16-1786, monoclonal plasma cell population with cytoplasmic kappa positivity. Ki-67 stains 7 percent of cells. Focal stromal hyalinization. Congo red stain for amyloid negative. No thyroidal tissue identified. 2. Right thyroid lobe excision Benign thyroid tissue with focal solid cell nest negative for malignancy. One out of two 1/2 perithyroidal lymph nodes positive for plasma cell tumor. 3. Laryngeal mass excision Plasma cell tumor /plasmacytoma 7 cm involving soft tissue and skeletal muscle. Tumor cells are positive for kappa and negative for lambda immunostains. Ki-67 stains 7 percent of cells. Focal stromal hyalinization and calcification. Congo red stain for amyloid negative

This patient was diagnosed in 2016 with renal cell clear cell and was coded to that. In 2018, the patient's liver lesion was resected and pathology revealed epithelioid angiomyolipoma perivascular epithelioid cell tumor (PEComa) (8714/3), a new term as of 2018. This was compared to the kidney slides and it was determined to be metastatic PEComa from the kidney. The physician's note states: The patient had a nephrectomy for a kidney tumor in 2016, excision of cutaneous melanomas, and resection of liver mass in 2018. These three cases were sent in consultation. The diagnosis of cutaneous melanoma was confirmed by a dermatopathologist of our department, (a separate report had been already issued). The kidney tumor is poorly differentiated composed of sheets of discohesive cells with markedly pleomorphic cells with frequent giant and bizarre cells. Most of the cells have abundant eosinophilic to clear cytoplasm. The nuclei are enlarged and pleomorphic. Multinucleated cells are numerous. Some cells have markedly enlarged nucleoli. Multifocal tumor necrosis is noted. Extensive lymphovascular invasion is observed. There are foci at the periphery of the tumor consisting of a proliferation of spindle cells with entrapped adipocytes consistent with minor element of unusual angiomyolipoma (see block A18). The liver tumor has histologic features that are similar to the poorly differentiated component of the kidney tumor.

A patient has a left breast cancer diagnosed in 2011; then has a "recurrence" in her lymph nodes in 2017. In 2018, she has a new left breast mass that is the same histology and behavior as the 2011 cancer. Based on the 2017 "recurrence" in the lymph nodes, this is not a new breast primary, is that correct?
