Benign mesenchymal liver hamartoma in an adult male: a case report and review of the literature.
Mesenchymal hamartoma of the liver is an uncommon benign lesion seen almost exclusively in children younger than two years of age. The first case was reported in 1903, and until now fewer than 200 cases have been reported. A 38-year-old male complaining of dull subcostal pain lasting for almost 10 months was found on abdominal ultrasound to have a focal lesion of the liver. He was referred to our Unit where imaging procedures (ultrasound and computed tomography) revealed a solid lesion, 8 centimeters in diameter, located in the IVb and V segments of the liver. There were no clear margins between the lesion and the gallbladder wall. Alpha-fetoprotein and carcinoembryonic antigen were within normal limits and carbohydrate antigen 19-9 was minimally elevated. There was no evidence of metastatic disease. Ultrasound-guided biopsy of the lesion was done and pathology report of a biopsy specimen suggested that the tumor was probably a benign mesenchymal hamartoma. The patient underwent a formal bi-segmentectomy (IVb and V segments) with cholecystectomy. Definitive pathology report confirmed the diagnosis of a benign mesenchymal hamartoma.
