Background/Purpose:
The association between liver infantile hemangioma and mesenchymal hamartoma is rare. This communication reports the clinical, radiologic, and pathologic features of 3 infants with concurrent liver hemangioma and mesenchymal hamartoma.
Methods:
We conducted a comprehensive search of the database of our Vascular Anomalies Center over the past 12 years (1999-2010) for the keywords mesenchymal hamartoma, liver, and hemangioma in a large cohort of patients with liver hemangioma. Medical records and imaging studies of multiple modalities were reviewed. The search included infants with histopathologically proven liver hemangioma and mesenchymal hamartoma confirmed by the clinical and imaging findings.
Results:
There were 112 children with the diagnosis of liver hemangioma; 3 of them (0.027%) had concurrent mesenchymal hamartoma. Mesenchymal hamartoma predates the appearance of multifocal liver hemangiomas in 1 patient.
Conclusions:
The rare coexistence of liver infantile hemangioma and mesenchymal hamartoma could be a true association.
