The first edition was published in 1989, so the current edition was sorely needed in light of new developments. The material is in nine chapters beginning with discussion of handling and reporting of specimens for pathologic examination. Aiming to make accurate pathologic evaluation an integral part of clinical decision making, Yu (pathology, Northridge Hospital Medical Center) presents gross and microscopic diagnostic features of various disease processes, emphasizing differential diagnosis. The book is abundantly illustrated, including representations of unusual as well as the more common variations of tumors.
