Overview
Mucinous cystic neoplasm (cystadenoma) of the liver is a very rare oncological entity. Preoperative diagnosis is challenging, because the spectrum of pathological liver masses manifesting with cystic morphology is very wide. A 55-year-old woman was found via CT scan to have a sharply demarcated, septated, multicystic tumoral mass in the left lobe of the liver. The serological test for echinococcosis was negative. A laparotomic resection of the affected lobe was performed, including complete excision of the tumorous mass. Grossly, it was a large multilocular cystic tumor measuring 19 × 18 × 16 cm. Histology revealed a mucinous cystic neoplasm (cystadenoma) of the liver with predominant enteric epithelial differentiation harboring mild dysplasia. In routine medical practice, hepatic cystadenoma is a rare condition. As our case report illustrates, it occurs almost exclusively in middleaged women, the clinical feature that is very helpful in differential diagnosis. Complete removal of the lesion and its thorough histological examination are crucial for establishing a definitive diagnosis, as it is a tumor with malignant potential.
