Do we code as prolactinoma when the tumor is immunoreactive for prolactin or must there be a definitive statement of ?

2. (2017) Pituitary lesion on imaging, MD diagnosis of

Current (2007) MP/H rule H9 states when there are multiple histologies in the same branch in Chart 1, code the more specific histology. These histologies are NOT in Chart 1, but prolactinoma seems to be a more specific type of pituitary adenoma. The next rule, H10 states to code the numerically higher code, 8272/0 (pituitary adenoma)?

3. (2017) Imaging diagnosis of pituitary macroadenoma with clinical diagnosis by MD of macroprolactinoma.

Current rules indicate when there is no path specimen that physician reference to type of tumor has priority over imaging.

Will these answers/histologies change with the upcoming 2018 Solid Tumor rules?

Patient diagnosed with multinodular and vacuolating neuronal tumor of the cerebrum. My research shows: Multinodular and vacuolating neuronal tumor of the cerebrum is a recently reported benign, mixed glial neuronal lesion that is included in the 2016 updated World Health Organization classification of brain neoplasms as a unique cytoarchitectural pattern of gangliocytoma. There is no code in ICD-O-3 for it, so do I report it and use 9492/0 or not ?

I have searched ICD-O-3 for a histology listing but could not locate. I also searched the SEER Inquiry database for possible answers, but none were found. The patient underwent a pediatric MRI of the brain of which final impression was: 1) Subependymoma nodules, cortical tubers, and SEGAs are seen bilaterally consistent with tuberous sclerosis.

Mixed odontogenic tumor consistent with dentinoameloblastoma, 9.5 cm, See Note: Tumor involves maxillary bone including hard palate, alveolar ridges, nasal cavities and maxillary sinuses bilaterally and buccal soft tissue. Lymphovascular invasion not identified. Perineural invasion not identified. Margins: Tumor involves right posterior bone (alveolar) margin. All other margins negative. Note: This is a rare hybrid tumor showing features of ameloblastoma producing pre-dentin/osteodentin matrix. Submucosal tumor is seen in the nasal cavities and palate. A congo red stain shows that the acellular dentin-like matrix fluoresces similar to collagen after polarization. Immunohistochemistry shows that the tumor cells are diffusely and strongly positive for p63, focally positive for CK19, and negative for CK5/6, SOX10, S100 and calretinin.

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
