Congenital hepatic cyst

Mucoepidermoid carcinoma was first described by L.E. PiANzoLA et al. in 1971. (222) It is a rare entity this sub-type constitutes only 2-3% of all CCC. Up to now, 41 cases have been reported. The tumour contains components of both adenocarcinoma and squamous cell carcinoma. It is discussed that this condition derives from a squamous metaplasia of the terminal ramifications of the bile canaliculi (222) or from adenocarcinoma cells. A combination of HCC and mucoepidermoid carcinoma has been observed. (219) This tumour contains components of both cell types. A male predominance was found. The clinical findings and laboratory data are similar to CCC. Pathogenesis is unknown various congenital cysts of the biliary tract (218) and non-parasitic cysts (221, 223) as well as hepatic cholelithiasis (usually associated with infection) have been proposed as aetio-logical factors. (217) Although its resectability was... 

A choledochal cyst is a rare congenital dilation of the hepatic duct of the liver and is due to a ductal plate malformation of the large hile ducts. They maintain continuity with the biliary tree. These cysts can he intrahepatic and/or extrahepatic (Kim et al. 1995).
