Objective:
To report the first case of primary epithelial-myoepithelial carcinoma (EMC) in the liver.
Methods:
The clinical manifestations, imaging characteristics, and histopathological changes of EMC in this case were described. The patient was a thirty-seven-year old female. A 10 cm lesion was detected in the right liver upon a routine examination. Following that, the CT scan, magnetic resonance imaging (MRI), repeated puncture biopsies, and serum alpha-fetoprotein (AFP) detection were done with no specificity and significance found.
Results:
Right hemi-hepatectomy was performed. The special double catheterization cannula was found in the histopathological examination, and the final diagnosis of EMC was proven by immuno-histochemical staining.
Conclusions:
Primary EMC is difficult to be finally diagnosed prior to the surgery. The diagnosis can be confirmed using pathological examination and immuno-histochemical staining of the specimen.
