Spindled cell lesion of smooth muscle origin (desmin and SMA are positive, CD34, S100, pancytokeratin, Pax8, MDM2 and CDK4 are negative). Many of the cells have hyperchromatic, bizarre-shaped nuclei. Mitotic activity is inconspicuous. There are no areas of necrosis. The overall findings in this biopsy is best classified as a "STUMP"; however, a leiomyosarcoma cannot be excluded.

This comment was added to the pathology report by the pathologist: A focus of neuroendocrine microtumor measured 350 micrometers, qualifying as a neuroendocrine microtumor. Focus was immunohistochemically positive for chromogranin and synaptophysin and negative for gastrin. The Ki-67/CD45 immunostain showed <1% positivity in microtumor.

This will be a tough one for registrars to recognize as non-reportable since the terminology contains sarcoma, so we just want to double check.

A question was posted to CAnswer forum 9/26/18 and answered stating that 8046 is not on the AJCC list of histologies for the lung chapter in the 8th edition. If the final diagnosis on the pathology report is just NSCLC, NOS with no subtype/variant, what histology/solid tumor rule would I use? In this situation, I am not able to query the pathologist. Would I code the histology to 8010 as per AJCC post?

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

Example 1: Physician states patient has an almost certain melanoma. Due to the patient's age, there is no plan to for any treatment or further workup. Almost certain is not listed as a reportable phrase, so typically we would not accession this case.

Example 2: Imaging states a diagnosis of renal cell carcinoma until proven otherwise. No additional workup is available at this facility. This terminology is also not seen on the ambiguous reportable terminology list but we are seeing it more often and wanted confirmation.
