Introduction:
The hepatic cystic tumour is a very rare neoplasm, representing about 5% of all cystic liver neoplasms. The preoperative diagnosis is difficult and can lead to confusion. The aim of this study is to analyze a number of cases operated at our centre with an histologic diagnosis of liver cystic neoplasms and also to describe the sintomathology, diagnosis and management as per the recent classification.
Methods:
A retrospective analysis was performed including all the cystic liver neoplasms operated between January 2000 and December 2019. The study was performed based on the pre-existing pathology archives. The 2010 previous cases were reclassified following the new 2010 OMS classification.
Results:
The study sample was of 10 patients, identifying 6 of them as mucinous cystic liver neoplasms, and the other 4 as intraductal papillary biliary neoplasms. The majority of the patients were women (8/10) and the median age was 47 years. Regarding the treatment, 3 hepatectomy and 7 enucleations were performed. Frozen section intraoperatively was not required in any case. In one case, variable cellular atypia with areas of adenocarcinoma was observed, and the patient received neoadyuvant chemotherapy with taxol and carboplatin. In all cases the resection margins were negative.
Conclusion:
Cystic liver neoplasms are infrequent tumours with a difficult differential diagnosis. Therefore, with a high radiological suspicious, the treatment should be a complete resection to avoid recurrences and malignancies.
