Adult hepatic mesenchymal hamartoma: an unusual case.

Mesenchymal hamartoma is a benign hamartomatous lesion with unknown histogenesis. It generally occurs in pediatric population and has been rarely reported in adults. We report an unusual case of a cystic mesenchymal hamartoma of liver in an 81-year-old elderly male. A provisional diagnosis of liver abscess was made and definitive histopathology confirmed the diagnosis. This case has been reported because of its rarity.
