Effusion Cytology is a practical manual in diagnosis and interpretation of body cavity fluid (BCF) specimens. This highly illustrated volume will provide handy information for residents, fellows, and general pathologists with a step-by-step guide to evaluation of BCF specimens with the specific goal of identification of malignancies. Use of ancillary techniques such as immunocytochemistry is discussed where appropriate. Special attention is given to the formulation of final cytologic reports of the diagnosis of difficult cases.
