The Frozen Section Library series provides concise, user-friendly, site specific handbooks that are well illustrated and highlight the pitfalls, artifacts and differential diagnosis issues that arise in the hurried frozen section scenario. Frozen Section Library: Lymph Nodes highlights the usefulness of techniques such as touch preparation cytology and fine needle aspiration (FNA) cytology, as well as FNA biopsy. This fascicle also suggests proper handling for subsequent ancillary studies, including flow cytometric, cytogenetic, and molecular studies. Special emphasis is given to the limitations of frozen section diagnosis in lymph node pathology. All chapters are written by experts in their fields and include the most up to date scientific information. This book serves as a very useful resource for physicians in the frozen section room and in intra-operative consultation situations dealing with, and interested in, this very complex field of diagnostic pathology. Frozen Section Library: Lymph Nodes is of great value to pathologists, residents, and fellows who diagnose pathologic processes involving lymph nodes. Cherie H.
