Question:

MP/H Rules/Histology--Breast: Patient has single invasive left breast tumor diagnosed in 2008. Final pathology diagnosis is "Invasive solid papillary carcinoma". No mention of ductal in report. What is histology?

Discussion:

Answer:

For cases diagnosed 2007 or later:

As of July 2010:

Code the histology 8503 [Infiltrating papillary adenocarcinoma].

This is solid papillary, not solid AND papillary carcinoma. Solid is an adjective modifying papillary, in other words, a subtype of papillary. We do not have a code for solid papillary, so we code to the NOS, papillary using rule H14.

History:

Before July 2010: Code the histology 8255 [adenocarcioma with mixed subtypes] according to rule H19.

Start with rule H10 and stop at rule H19. Rule H19 is the first rule that applies to this unusual case.
