**For any laboratory performing cytologic examinations of serious fluids, by either the hematologic' (Romanowsky) or the Papanicolaou technique, this book is essential.'B. Naylor, Cytotechnologist's Bulletin,** 1990

`Although this practical and useful book will be of greatest interest to pathologists, all medical practitioners who encounter patients with fluid collections of the serious cavities will find it interesting. It belongs in the reference libraries of all laboratories performing body fluid cytology and of all medical practitioners using the results.'
Annals of Internal Medicine, 114 (8) April 1991

`I thoroughly recommend it as an essential reference book for anyone working in this field.'
