Mucinous Cystic Neoplasm of the Liver- Three Rare Cases with Different Clinical Impressions

Mucinous Cystic Neoplasm of the Liver (MCN-L) is a rare cystic epithelial tumour that does not communicate with bile ducts and comprising ovarian-type mesenchymal stroma and mucinous epithelium. Though it is a benign tumour it may be associated with invasive carcinoma. Therefore, complete surgical excision and extensive sampling is important to prevent recurrence and detect associated malignancy. Its rarity precludes its recognition as it can mimic other cystic liver lesions. Awareness of this rare entity is essential as it lacks well-defined characteristics and poses a considerable diagnostic challenge preoperatively. Here we present three cases of MCN-L with different clinical impressions preoperatively. All three were women who presented with abdominal pain or discomfort and were found to have cystic lesions in the liver which subsequently underwent excision. The preoperative diagnoses were hydaticd cyst, hepatic abscess and simple liver cyst in case 1 ,2 and 3 respectively. Histopathology of all three cysts were MCN-L with no high grade dysplasia or invasive carcinoma.
