Epidermoid Cyst of the Liver Complicated by Microscopic Squamous Cell Carcinoma: Ct, Ultrasound, and Pathology

Abstract Though cystic hepatic lesions may have features that help characterize them by noninvasive imaging modalities, these findings are often nonspecific and may be unable to establish the presence of malignancy. This is illustrated here by describing an epidermoid cyst of the liver containing microscopic foci of squamous cell carcinoma. The importance of totally resecting an epidermoid cyst of the liver is emphasized.
