Intraoperative Frozen Sections presents diagnostic challenges involved in the evaluation in the pathology lab of specimens obtained during surgery through the case experience of expert pathologists. Sixty three problems cover the wide range of approximately of problems encountered in intraoperative consultations. Each presentation provides the case information as presented to the consultant, the evaluation and analysis of the specimen, discussion of the results and teaching points observed in the case, and an overall comment providing additional context for the diagnostic problem that has been presented. This problem-oriented format makes the book a superb reference resource for the working diagnostician and an ideal teaching tool for the resident or fellow. Coverage includes paediatric specimens and there is a section describing recognition of artifacts. Each case presentation is supported by several high-quality colour photomicrographs with detailed explanations of each image, including images of the permanent sections and immunostains where applicable. Features of Intraoperative Frozen Sections Include: Cases outline expert approach to diagnostic problems and technical issues most likely to be encountered in frozen section analysis. Coverage includes pediatric specimens and recognition of artifacts. Special emphasis on difficult problems and avoiding diagnostic pitfalls. Provides common differential diagnoses for specific lesions seen in frozen section analysis (e.g. mimics of renal neoplasia). Nearly 500 high-quality colour photomicrographs and detailed discussions of diagnostic features of each image.

The evolution of the classification of neoplasms of the urinary passages has changed greatly since Friedman and Ash published the first series AFIP fascicle on the urinary bladder in 1959. In their classification, there were four variants of urothelial neoplasia, some adenomas, adenocarcinoma, and smooth muscle and lymphoid tumors. Today the classification continues to accrue entities based upon morphology, immunophenotype, and compelling clinical associations. The classification of renal cell carcinomas has undergone a profound transformation, with the emergence of many new entities, often with characteristic genetic alterations, with significant implications for prognosis and treatment. This comprehensive, detailed, and highly illustrated fascicle is a remarkable resource to surgical pathologists and other specialists who treat patients with tumors of these sites.
