Hepatobiliary cystadenoma exhibiting morphologic changes from simple hepatic cyst shown by 11-year follow up imagings

Simple liver cyst: always a benign entity?

We read with interest the case report of Fukunaga N et al about a Hepatobiliary cystadenoma exhibiting morphologic changes from simple hepatic cyst shown by 11-year follow up imagings, published in World Journal of Surgical Oncology 2008, 6:129 (11 December 2008). <br> <br>Years ago (2005) we also published in Dig Dis Sci a case of a cystadenoma after years of a diagnosis of a simple liver cyst. ( Nonparasitic simple liver cyst: always a benign entity? Unusual presentation of a cystadenoma. Frider B, Rodriguez JA, Porras LC, Amante M., Dig Dis Sci. 2005 Feb;50(2):317-9. ) This case has similar features of the case reported by Fukunaga et al, with the same considerations about this benign disease, and the need of follow up to exclude potential changes in the cyst. <br>I regret that Dr. N Fukunaga has not read our case report, and then was not included in the bibliography. The relative high frequency of liver cysts, the scarce of publications about the potential cystadenoma transformation of simple cysts and the poor follow up assigned for this type of simple liver cyst in clinical practice support the need of increase the knowledge of this type of situations. <br><br>Sincerely<br><br>Bernardo Frider MD<br>Head Deptartment of Medicine-Hepatology<br>C.
