MP/H Rules/Multiple Primaries/CS Extension: How many primaries are to be accessioned when tumors are present bilaterally in the pleura and fallopian tubes? See Discussion.
MP/H Rules/Multiple Primaries--Thyroid: How many primaries should be coded if there is a clinical diagnosis of recurrent thyroid carcinoma in 3/08 in a patient with a history of thyroid carcinoma diagnosed in 1995 with a 2002 clinical recurrence? See Discussion.
MP/H Rules/Multiple Primaries--Melanoma: Is there a difference between multiple primary rules M6 and M7 because both rules state that tumors occurring more than 60 days apart are to be reported as multiple primaries? See Discussion.
MP/H Rules/Multiple Primaries--Lung: Please clarify the multiple primary rule M6 and the explanatory note that states when there is a single tumor in each lung, they are to be reported as multiple primaries unless stated or proven to be metastasis. See Discussion.
MP/H Rules/Multiple Primaries--Lung: How many primaries should be reported when an "adenocarcinoma" is discovered in one of several new nodules at the scar in a lung and it is less than a year after a wedge resection for a diagnosis of "bronchioalveolar adenocarcinoma" in the same lung? See Discussion.
MP/H Rules/Multiple Primaries--Lung: How do we apply the MP/H rules if a pathologist states a patient has multiple reportable primaries after he compares an October 2006 RLL lung specimen with a March 2009 RML lung specimen? See Discussion.
MP/H Rules/Multiple Primaries--Head and Neck: How many primaries are to be accessioned for a case in which a second tumor occurs in an area previously involved by direct extension from a prior primary located in an adjacent site? See Discussion.
MP/H Rules/Multiple Primaries--Head & Neck: How many primaries should be reported when an invasive squamous cell carcinoma of the right mandibular body (C06.9) was diagnosed in 2004 (treated with surgery and radical neck dissection), and an invasive squamous cell carcinoma of the left buccal mucosa (C06.0) was diagnosed in 2007? See Discussion.
MP/H Rules/Multiple Primaries--Breast: How many primaries should be accessioned if two tumors are present in the same breast, a 1.7 cm colloid carcinoma and a 1.5 cm colloid carcinoma with infiltrating ductal carcinoma? See Discussion.
MP/H Rules/Multiple Primaries--Breast: How many primaries are to be abstracted when two tumors occur in one breast and both are ductal with the smaller tumor representing tubular carcinoma [variant]? See Discussion.
