Solid Tumor Rules (2018)/Histology--Lung: How is histology coded when the term "predominant" is used to describe solid adenocarcinoma, acinar adenocarcinoma, etc.? Pathology reports often say "See Synoptic" (also known as the College of American Pathologists (CAP) protocol) included in the Final Diagnosis rather than including all the detail. Based upon the new Solid Tumor Rules for lung, predominant/predominantly is no longer a subtype/variant and should not be coded unless there is a specific code/subtype-variant for the NOS in Table 3, e.g., adenocarcinoma, lepidic predominant. See Discussion.
