Abstract

Mucinous cystic neoplasm of the liver is a rare cystic neoplasm accounting for approx. 5% of cystic liver in the liver parenchyma. We describe the histomorphology and immunophenotyping features of MCN-L in a 52-year-old woman who came to the surgical department with complaints of pain abdomen for 1.5 months. The ultrasonography showed a septated cyst located centrally in the liver. The CT abdomen showed a large hypodense multiloculated cystic lesion in the liver with thin enhancing septae and multiple small cysts involving the entire left lobe with extension into the right lobe and having a large infra-hepatic exophytic component. A provisional diagnosis of a Hydatid cyst was made. Drainage of the cyst with laparoscopic deroofing was done. Histopathology examination showed a cyst lined by cuboidal to columnar epithelium with mucinous cytoplasm and basally oriented nuclei. Subepithelium shows ovarian-like stroma. MCN-L has a lower frequency as compared to the counterpart of MCN in the pancreas, and further molecular studies are necessary to clarify the biology of MCN-L. The relevance of this rare entity's clinical and radiological suspicion, histological recognition and immunohistochemistry is emphasised.

Keywords: Mucinous cystic neoplasm of the liver (MCN­ L), Ovarian­ like stroma, Intra­ hepatic biliary tract dilatation (IHBRD).
