‘Watchful Waiting’ May Be an Appropriate Treatment for ELBW Infant with Hepatic Mesenchymal Hamartoma

Hepatic mesenchymal hamartoma (hmh) is an uncommon benign tumor of childhood. typically a patient will present with an enlarged, nontender abdominal mass. no specific panel of laboratory tests is characteristic of hmh. laboratory studies often reveal normal liver function tests and various tumor markers, including human chorionic gonadotropin, alpha fetoprotein, and vanillylmandelic acid, are usually negative. abdominal ultrasound can demonstrate either a multicystic or solid mass.
