Mucus secreting columnar epithelium with dense ovarian like stroma is typical histology. It can be mucinous cystadenoma; borderline; in situ; mucinous cystadenocarcinoma. Mucinous tumours may show high levels of CEA but low levels of amylase. Presentations may be mass abdomen (large epigastric mass, non mobile, not moving with respiration), abdominal pain, back pain.
