Answer 2
Elevated serum a-fetoprotein level. Laboratory parameters are usually nondiagnostic in mesenchymal hamartoma.
a-Fetoprotein and liver enzymes may be normal or slightly increased. Elevation of tumor markers, including serum ßhuman chorionic gonadotropin, is not associated with mesenchymal hamartoma, which is typically a benign tumor. Mesenchymal hamartoma does not affect the hematopoietic system.
