Surprisingly and fortunately, a peripancreatic lymph node removed during surgery (0.7 cm maximum diameter) was shown to contain tumour cells of the same histotype of primitive breast cancer and showing both ER and PR positivity, apparently stronger membrane signal for HER-2 (Figure 1), CK7 and 19 positivity (data not shown). The gene discussed is KRT7; the disease is breast carcinoma.
