KRT14 and carcinoma: In our “triple-negative” FMCs we evidenced the appearance of CK5_6 in the 42.6% of the carcinomas (7.8%, average of positive neoplastic cells) and CK14 in the 91% of the carcinomas (32%, average of positive neoplastic cells), comparable to previous findings [17,25], and possibly suggestive of a BLBC phenotype [17].
