20081077 MP/H Rules--Ovary: How do you code histology for a diagnosis of "clear cell CA, predominately cystic."
20071108 MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries?
20081120 MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion.
20071128 MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
20110140 MP/H Rules/Behavior--Breast: How are behavior and histology coded when the pathology report final diagnosis is "ductal carcinoma in situ and lobular carcinoma in situ" if the microscopic examination section of the same pathology report states there are "foci suspicious for microinvasive carcinoma"? See Discussion.
20081044 MP/H Rules/Behavior--Melanoma of Skin: How are histology and behavior coded for a "malignant melanoma in situ with regression"? See Discussion.
20081062 MP/H Rules/Date of Diagnosis/Behavior--Brain and CNS: How many primaries would be reported when a December 2004 MRI shows a pineal region mass with the major differential consideration being pineocytoma; a November 2007 MRI that shows the mass has almost tripled in size; and the December 2007 resection final diagnosis is consistent with pineoblastoma? How would diagnosis date[s] and behavior code[s] be coded? See Discussion.
20081025 MP/H Rules/Histology--Anus: What is the correct histology code and MP/H histology rule to use for AIN-3 arising in a polyp? See Discussion.
20130222 MP/H Rules/Histology--Bladder: How is the histology coded for a single bladder tumor showing invasive urothelial carcinoma with extensive divergent differentiation including small cell carcinoma, micropapillary carcinoma, and squamous cell carcinoma features? See Discussion.
20110091 MP/H Rules/Histology--Bladder: How is this field coded for a patient with ureter specimen with "high grade urothelial carcinoma with adenocarcinoma differentiation" and a TURB specimen with "urothelial ca, high grade, a biphasic pattern with cautery-distorted urothelial carcinoma and adenocarcinoma"?
