The WHO bluebook classifies certain breast carcinomas as 'special' types, if they show certain characteristic histological features. These special types are sometimes loosely included in the loose label of invasive ductal carcinoma to distinguish them from invasive lobular carcinoma.

If a >90% of a tumour is composed of a 'special type', it is considered pure and labelled as in the list above. If one of the special types accounts for 50%, then is is classed as a mixed tumour, e.g. invasive carcinoma of mixed mucinous and no special type. All other tumours are classed as invasive carcinoma of no special type. | If a >90% of a tumour is composed of a 'special type', it is considered pure and labelled as in the list above.
