Reportability--Heme & Lymphoid Neoplasms: Are the terms EBV positive B-cell lymphoproliferative disorder with or without the term "of the elderly" and iatrogenic EBV positive lymphoproliferative disorder reportable? See Discussion.
Histology--Heme & Lymphoid Neoplasms: Is histology coded to AML, NOS [9861/3] for a bone marrow biopsy with a diagnosis of acute myeloid leukemia evolving from myelodysplastic syndrome (MDS) if the cytogenetics revealed trisomy 13? See Discussion.
MP/H Rules/Histology--Esophagus: Will the AJCC TNM 7 having separate stage groupings for squamous cell carcinoma and adenocarcinoma result in coding histology for a tumor of mixed squamous cell carcinoma and adenocarcinoma to squamous cell carcinoma because it has the poorer prognosis? See Discussion.
Surgery of Primary Site--Breast: How is this field coded for a BILATERAL nipple sparing mastectomy given that SINQ 20110094 indicates that a nipple sparing mastectomy should be coded to 30 [subcutaneous mastectomy] but there is no code for bilateral subcutaneous mastectomies?
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.
Reportability--Colon: Is a polypectomy that is suspicious for invasive adenocarcinoma followed by a partial colectomy with no residual neoplasm reportable? See Discussion.
MP/H/Histology--Lung: What is the histology code for "heterologous biphasic sarcomatoid carcinoma of the lung with prominent rhabdomyoblastic and adenoca differentiation"?
MP/H Rules/Histology--Lung: How is micropapillary adenocarcinoma of the lung coded given that a literature search indicates that this is a distinct subtype of adenocarcinoma of the lung with poor prognosis?
MP/H Rules/Multiple primaries--Breast: How many primaries are to be abstracted for a patient with a history of right breast ductal carcinoma in situ diagnosed in 2007 treated with bilateral mastectomies and a right chest wall mass excised in 2010 that revealed infiltrating ductal carcinoma? See Discussion.
MP/H Rules/Multiple primaries--Head & Neck: If a 1991 neuroesthesioblastoma [9522/3] of the nasal cavity has subsequent recurrences of the same histology but later "recurs" in 2008 with "sarcoma, NOS, high grade" on a biopsy and a "high grade fibrosarcomatous transformation of esthesioneuroblastoma" [8810/3] on resection, should the subsequent tumor be reported as a new primary if the clinician continues to refer to the tumor as a "recurrence"? See Discussion.
