Solid Tumor Rules/Multiple Primaries--Testis: How many primaries and what M Rule applies when metastatic seminoma is diagnosed greater than 40 years after a left testicular teratoma with yolk sac tumor and embryonal carcinoma? See Discussion.

First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion.

Reportability/Behavior--Skin: Is an "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" with an ICDO-3 histology code of 8830 reportable with a behavior code of 3 or is it nonreportable with a behavior code of 1?

Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?

MP/H Rules/Multiple primaries--Melanoma: How many melanoma primaries should be abstracted if, during the workup for a metastatic melanoma of an unknown cutaneous site, an in situ melanoma is also discovered? See Discussion.

Diagnostic confirmation: When a CT guided Fine Needle Aspiration is performed and the pathology report indicates smears and cell block were prepared, if the diagnosis is positive for cancer, can you code diagnostic confirmation as 2 (positive cytology) because of the cell block?

Surgery of Primary Site/Multiple primaries--Breast: Should the Surgery of Primary Site for the 2020 diagnosis be coded 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) when a partial mastectomy and axillary lymph node dissection are performed for a 2011 right breast primary and a subsequent 2020 right breast primary is treated with a total mastectomy only? See Discussion.

MP/H Rules/Multiple primaries--Breast: Does rule M10 apply in this situation?

L breast biopsy = INVASIVE DUCTAL CARCINOMA

L breast simple mastectomy = 2.0 cm INVASIVE DUCTAL CARCINOMA with an incidental finding of separate 1.0 cm INVASIVE LOBULAR CARCINOMA; pathologist specifically states the tumors are morphologically different. The tumors are both pure Ductal/pure Lobular.

MP/H/Histology--Pituitary: Would you code Crooke cell adenoma as 8272/0 pituitary adenoma?

Reportability/Breast: Is lobular carcinoma in situ (LCIS) reportable? The eighth edition, American Joint Commission on Cancer (AJCC) Cancer Staging Manual does not stage LCIS.
