MP/H Rules/Reportability--Ovary: Should an ovarian tumor with the histology of mixed epithelial borderline tumor with multiple foci of intraepithelial carcinoma be accessioned based on the presence of a foci of intraepithelial carcinoma? See Discussion.
MP/H Rules/Recurrence--Skin: If a pathologist does not review the August 2008 slides, how many primaries are accessioned for a patient diagnosed and treated for a dermatofibrosarcoma protuberans of the left upper inner arm in August 2008 who subsequently had a "recurrence" noted in October 2010 located in the scar of the original primary?
MP/H Rules/Recurrence--Breast: Do we use a pathologists comment of "recurrent ductal carcinoma" found in the pathology report for a new specimen to determine whether the new specimen actually represents a new primary or recurrent disease? See Discussion.
MP/H Rules/Primary site: What is the primary site and histology for a focus of papillary thyroid cancinoma, follicular variant, arising in thyroid tissue of mature cystic teratoma of the ovary?
MP/H Rules/Primary site: Can you clarify how you interpreted the term "synchronous" to appropriately code the primary site to C68.9 [urinary tract] for SINQ 20110119 and did not use that code for SINQ 20100025 when both cases used MP/H Rule M8 to determine the number of primaries? See Discussion.
MP/H Rules/Primary site/Histology--Colon/Rectum: How are the primary site and histology to be coded for a diagnosis of familial polyposis with malignant tumors in the sigmoid and rectum? See Discussion.
MP/H Rules/Primary Site--Bladder: How is the primary site coded when a patient is diagnosed with synchronous, non-invasive papillary urothelial carcinomas of the bladder and renal pelvis? See Discussion.
MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
