Neuroblastoma is a malignant tumor of primordial neural crest origin. It usually develops along the sympathetic nervous system, such as the adrenal glands or paramedian sympathetic chain and metastasizes to the liver most frequently. However, a primary hepatic neuroblastoma has not been reported yet. Here, we report a case of 29-year-old woman who presented with a solitary hepatic mass. Grossly, the mass was large, creamy, rubbery firm, and showed focal hemorrhage and central cavitation. Microscopically, the tumor cells were arranged in small nests of spindle to ovoid cells with abundant neuropil. The neuroblastic nature of the tumor was confirmed by immunohistochemistry and electron microscopy. No extrahepatic mass was found, despite a thorough systemic survey such as chest and abdominopelvic computed tomography (CT) scans and a whole body positron emission tomography-CT study. To the best of our knowledge, this is the first report of a bona fide primary hepatic neuroblastoma.

Beckwith-Wiedemann syndrome is a well-known overgrowth syndrome associated with the presence of a wide variety of anomalies and increased risk of cancers. Less frequently, benign neoplasms also develop. We report a female infant with Beckwith-Wiedemann syndrome who developed a mesenchymal hamartoma of the liver. The patient was born with macroglossia, ear lobe crease, and abdominal distension.
Laboratory data showed hypoglycemia, and magnetic resonance image revealed both adrenal enlargement, enhancing mass of the pancreas, and multiple hepatic nodules. The histologic findings of the resected distal pancreas and both adrenals were those of Beckwith-Wiedemann syndrome. Microscopic findings of the liver biopsy specimens were compatible with mesenchymal hamartoma. Hamartoma of the urinary bladder, cardiac fibrous hamartoma, and mixed hamartoma of the liver have been documented previously in association with Beckwith-Wiedemann syndrome. However, to our knowledge, this is the first case report of hepatic mesenchymal hamartoma in Beckwith-Wiedemann syndrome. Because of the paucity of hamartomas in childhood, we should be cautious of other features of Beckwith-Wiedemann syndrome and the present case extends the spectrum of tumor formation in this syndrome.
