Question:

MP/H Rules/Multiple primaries--Breast: Does breast Rule M10, 'Tumors that are lobular (8520) and intraductal or duct are a single primary" apply if you have two tumors in the same breast, one ductal and the other tubulolobular (8524) or are they separate primaries per Rule M12?

Discussion:

Answer:

Apply Rule M10 to this case. Tubulolobular is now classified as a variant of lobular. Code to lobular, NOS (8520) because Tubulolobular does not have a specific ICD-O-3 code.
