Cytopathologic diagnosis of liver mass lesions

Abstract

The liver is a common site for metastatic malignancies, particularly from the gastrointestinal tract. It also may be involved by primary neoplasms, both benign and malignant. Cytopathologic examination of mass lesions of the liver with pertinent use of ancillary studies is a useful method of establishing a correct diagnosis for patient management. The authors reviewed the literature for articles pertaining to cytologic characteristics of specific tumor types, utility of immunohistochemical markers and pertinent molecular studies, differential diagnoses and pitfalls. © Pioneer Bioscience Publishing Company.
