A 73-year-old woman presented with dull pain in the epigastric region, a rapid feeling of fullness upon eating and a weight loss of 10 kg in 6 months. Further examination showed linitis plastica due to a signet ring cell carcinoma in the stomach, multiple bone metastases, and an occult, small breast tumour. Immunohistochemical comparison of the tumours strongly suggested that all cases involved a metastasised breast carcinoma. At check-up after one year of tamoxifen treatment, the complaints had disappeared and the activity of the tumour marker had dropped. Gastric metastases from breast carcinoma are rare. Nevertheless, this possibility should be kept in mind in women presenting with malignancies of the stomach and mastopathy. Hormonal treatment and chemotherapy may result in reasonable palliation.

Objective: This study aimed to examine the relationship between low-grade appendiceal mucinous neoplasms (LAMNs) and serrated polyps (SPs) of the appendix, both characterized by KRAS mutations and overlapping morphologic features.
Methods: We analyzed 27 cases of LAMN and 24 cases of SP from archival records, reviewed pathology, and performed molecular analysis on select cases. Four cases initially diagnosed as LAMN were excluded for not meeting diagnostic criteria, and 1 SP case was reclassified as LAMN.
