Primary mixed germ cell tumour of the liver--a case report.

Germ cell tumours in liver are uncommon. Fewer than 20 cases have been reported in the literature. Primary mixed malignant germ cell tumours of liver are even rare. Here we describe a case of primary mixed malignant germ cell tumour of left lobe of liver in a two and half year old male boy. This is the first reported case of primary mixed malignant germ cell tumour with components of yolk sac tumour and mature teratoma in an infant. The patient complained of gradual increase in abdominal distension, upper abdominal pain and loss of weight. Ultrasonography and computed tomography of the abdomen revealed a large hepatic mass. Serum alpha-feto protein levels were raised. Left lobectomy of liver was done and chemotherapy was initiated. Histopathology of specimen disclosed yolk sac tumour and mature teratoma. Levels of serum alpha-feto protein declined rapidly. Widespread intrahepatic metastasis developed and patient died due to liver dysfunction after six months of left lobectomy.
