Mesenchymal hamartoma of the liver (MHL) is a rare benign tumor usually found in childhood, especially during the first two years. MHL is extremely rare in adults. Most reported cases present with a slow growing abdominal mass. It is thought to be a developmental anomaly and consists of bile ducts, hepatocytes and mesenchymal tissue. We report a case of mesenchymal hamartoma of the liver in an adult male with a brief review of the literature.

This paper presents an unusual solid mesenchymal hamartoma of the liver (MHL) in adult. A well defined solid mass in the left lobe of the liver was found in a 57-year-old female. Preoperative radiologic examinations demonstrated solid mass with multifocal calcifications abutting the gallbladder. By light microscopy, the lesion was composed of dense fibrous stroma with hyalinization, bile ducts and thick-walled vessels without hepatocytes. The solid and hyalinized mesenchymal component would suggest an unusual degenerative change representing a burnt-out MHL.

Splenic hamartomas are rare benign tumors, which are usually small in size and asymptomatic and which are discovered incidentally at surgery or autopsy. The authors report on a case of splenic hamar toma in a 35-year-old man with intermittent left upper quardrant pain, who underwent an elective splenc tomy. Final pathology confirmed diagnosis of a hamartoma of the red pulp in the spleen. The patient's symptoms were resolved after the splenectomy. A splenic hamartoma should be kept in mind in the differential diagnosis of splenic tumors. The authors suggest that a splenectomy is indicated in cases where malignancy cannot be excluded and in cases of associated clinical symptoms or hematologic disorders.
