Solid Tumor Rules/Multiple Primaries--Prostate: How many primaries are accessioned when a 2023 liver biopsy diagnosed metastatic small cell carcinoma (SmCC) of the prostate following a 2018 radical prostatectomy treated diagnosis of prostatic adenocarcinoma?  See Discussion.

Solid Tumor Rules/Multiple Primaries--Breast: How many primaries and which Breast Solid Tumor Rules (STR) M Rule applies when a patient has synchronous, separate/non-contiguous breast tumors which are a ductal carcinoma and a separate lobular carcinoma? See Discussion.

MP/H Rules/Multiple primaries--Breast: Can we accession two breast primaries when imaging is "suspicious for malignancy" on both breasts but only one biopsy is taken and is histologically confirmed, and assume bilateral complete response to neoadjuvant chemotherapy with bilateral mastectomies negative for residual cancer? See Discussion.

MP/H Rules/Multiple primaries--Penis: How many primaries should be reported for a diagnosis of invasive squamous cell carcinoma (SCC) of the penis in 6/2011, treated with excision and fulguration followed by 10/2014 penile lesion found to be SCC with basaloid features focally highly suspicious for invasion? Clinically, the 2014 tumor is stated to be in situ and recurrent penile cancer and follow-up in 2/2015 indicates there was no evidence of tumor following treatment. Subsequently, in 3/2016 the patient has another penile lesion biopsy showing SCC in situ suspicious for invasion, clinically stated to be recurrent. See Discussion.

Reportability/MP/H Rules: Where can I find documentation on how to accession malignant tumors in transplanted organs? See discussion.

MP/H Rules/Multiple primaries--Lung: How many primaries should be accessioned if patient has a LUL lung biopsy with squamous cell carcinoma and subsequently a station 4L node biopsy with small cell carcinoma? See Discussion.

Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion.

Solid Tumor Rules (2018/2021)/Multiple Primaries--Brain and CNS:  How many primaries should be accessioned and what multiple primaries/histology rules apply to a meningioma of the spinal meninges and a meningioma of the cerebral meninges? See Discussion.

Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with large cell transformation equivalent to a diagnosis of diffuse large B-cell lymphoma (DLBCL) without mention of Richter transformation or Richter Syndrome? See Discussion.
