Soft tissue aspiration cytopathology

Abstract

Aspiration cytopathology of soft tissue mass lesions using FNA biopsy can be an accurate and minimally invasive method for the initial pathologic diagnosis of primary benign and malignant soft tissue masses, for the pathologic confirmation of metastatic tumors to soft tissue, and for the documentation of locally recurrent soft tissue neoplasms. FNA cytopathology is capable of specifically subtyping a large percentage of primary and metastatic soft tissue tumors if cellular material either in the form of a cell block or flow cytometry is obtained in addition to cell smears.
