Mucoepidermoid carcinoma arising in the liver is a rare malignant tumor which reperted only about 10cases to date. Several terms, such as adenosquamous carcinoma, adenoacanthoma, and mucoepidermoid carcinoma, have been used for carcinomas
containing
both adenomatous and squamous elements. Most of mucoepidermoid carcinoma have been reported in the salivary gland of primary site, but this tumor can also arise in many other regions of the body, such as lung, esophagus, pancreas, uterus,
bladder,
anus
and etc.
Mucoepidermoid carcinoma of the liver morphologically resembles that of the salivary gland. Histologically, this tumor consists of mixture of squamous cells, mucus-producing cells, and intermediate cells. Intercellular bridges and keratinization
are
also present in the epidermoid area of the tumor.
We experienced a case of mucoepidermoid carcinoma arising in the liver of 68-year-old man. The tumor, measuring about 10x10cm sized, was noted in left lobe of the liver with invasion to adjacent organs. The exploratory laparotomy was done and we
obtained tissue from the tumor nodule protruding to the liver surface. Microscopically, this tumor revealed squamous element and intermingled mucoid element. And intercellular bridges and keratinization were noted in the epidermoid area.
So we report this case of mucoepidermoid carcinoma of the liver with a literature review.
