MP/H Rules/Histology--Testis: How should histology be coded for a testicular primary with a combination of teratoma, yolk sac tumor and embryonal carcinoma? See discussion.

Histology--Sarcoma: What is the histology code for epithelioid angiosarcoma?

Histology/Behavior--Brain and CNS: How are histology and behavior coded for a diagnosis of pineal anlage tumor in an infant? See Discussion.

Solid Tumor Rules/Histology--Brain and CNS: What is the histology code for low grade glioma? See Discussion.

Histology--Brain and CNS: What morphology code should be assigned to a low-grade glial/glioneuronal neoplasm? See Discussion.

MP/H Rules/Histology--Brain and CNS: What is the code for Rosette-forming glioneural tumor from a pathology report of a brain tumor biopsy for a date of diagnosis in 2015? See Discussion.

Tumor Size/Neoadjuvant Treatment:  If a patient discontinues neoadjuvant therapy and then has surgery, how is the pathologic tumor size coded with the pathologic tumor size greater than the clinical tumor size? Currently, we are instructed to code 999 for the pathologic tumor size when neoadjuvant therapy is given; what happens when neoadjuvant chemotherapy is discontinued after 3 cycles (plan for 4 cycles)? 

EOD 2018/EOD Primary Tumor/EOD Mets--Lung: Is EOD Primary Tumor coded to 500 and EOD Mets 10 when there are bilateral lung nodules with nodules in same lobe as the primary tumor? How is EOD Primary Tumor coded when separate tumor nodes are in an ipsilateral lung but there is no documentation as to whether it is in the same or different ipsilateral lobe from the primary tumor?

EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.
