B Low-grade cytologic atypia with basally located small round nuclei in the peritoneal disseminated mucinous neoplasm. C High-grade cytologic grade atypia showing increased nuclear-cytoplasmic ratio in the peritoneal disseminated mucinous neoplasm. D SMAD4 immunohistochemistry showing loss of SMAD4 expression in the peritoneal disseminated mucinous neoplasm, consistent with the presence of SMAD4 mutation.
