Frozen Section Library – serie

Frozen sections are performed for the purpose of rapid diagnosis while a patient is undergoing surgery, usually under general anesthesia, as a basis for making immediate treatment decisions. Therefore, frozen section diagnosis is often a highly demanding situation for the pathologist who must render a diagnosis quickly and a crucial determination for the patient and surgeon. In addition to the need for rapid recall of differential diagnoses, there are many pitfalls and artifacts that add to the risk of frozen section diagnosis that are not present with permanent sections of fully processed tissues that can be examined in a more leisurely fashion. Most standard pathology textbooks, both general and subspecialty, largely ignore the topic of frozen section. Few textbooks have ever focused exclusively on frozen section diagnosis and those textbooks that have done so are now out-of-date and have limited numbers of black and white figures. None has emphasized the education of the surgeon in terms of frozen section benefits, limitations or proper utilization. The Frozen Section Library series will provide convenient, user-friendly handbooks for each organ system to expedite use in the hurried frozen section situation. These books will be small and light-weight, copiously color illustrated with images of actual frozen sections, highlighting pitfalls, artifacts and differential diagnosis. These books will also include perspectives for the surgeon and for communication with the surgeon and suggest ancillary procedures (for example, when to take tissue for microbiology cultures). Each 5 X 8 book is estimated to be about 200 to 250 pages in toto with 100 to 150 color figures each.As a handbook for practicing pathologists, these books will be indispensable aids to diagnosis and avoiding dangers in one of the most challenging situations that pathologists encounter. Problems, such as differentiation of benign processes from malignant neoplasms which may be more difficult on frozen section than permanent section and which have a serious impact on the surgeon’s immediate treatment decisions, will be emphasized. Rapid consideration of differential diagnoses and how to avoid traps caused by frozen section artifacts will be readily accessible to the users of the handbooks. A series of concise, easy-to-use, well-illustrated handbooks alleviates the often frustrating and time-consuming, sometimes futile, process of searching through bulky textbooks that are unlikely to illustrate or discuss pathologic diagnoses from the perspective of frozen sections in the first place. Tables and charts will provide guidance for differential diagnosis of various histologic patterns.The advantages of a series of organ-specific handbooks, in addition to the ease-of-use and manageable size, is that (1) it allows more comprehensive coverage of more diagnoses, both common and rare, than a single volume that tries to highlight a limited number of diagnoses for each organ and (2) it allows more detailed insight by permitting experienced authorities to emphasize the peculiarities of frozen section for each organ system. Although some differences in practice of frozen section exist between different institutions, such as differing policies regarding whether or not to perform frozen section on specific types of specimens, these differences are generally not significant and can be discussed ( an organ-specific handbook by an expert in that organ system permits more opportunity for this type of discussion). Touch preparations, which are used for some organs such as central nervous system or thyroid more often than others, will be appropriately emphasized and illustrated according to the need for each specific organ. This series will be highly valuable to practicing surgical pathologists, both community and academic, and to pathology residents and fellows. The perspectives provided will also bevaluable to surgeons and especially to surgery residents and fellows who must answer questions about pathology and frozen section on their board examinations. These handbooks will be easily portable by the individual but it is envisioned that many departments will want to also keep a series readily available in the frozen section laboratory.

Frozen sections are performed while a patient is undergoing surgery as a basis for making an immediate diagnosis that will impact treatment decisions.

Intraoperative frozen section interpretation is the base for treatment for the patient within the operating room. It requires immediate answer for the surgeon’s specific question and the subsequent consequences are frequently irreversible. The pathologist should be very familiar with the related differential diagnosis of the involved organ. Additionally, the pathologist needs to know many pitfalls and freezing artifacts in each organ and the clinical implications each diagnosis may result in. Frozen Section Library: Head and Neck will provide a convenient, user-friendly handbook to expedite use when performing intraoperative consultations on head and neck specimens. This book will be 5 X 8 and is estimated to be about 200 to 250 pages in toto with 100 to 150 color figures. An organ and clinical scenario based approach will be used in this book. This book will be divided into chapters based on the organs and anatomic locations. Within the chapter, a consistent format with the critical issues as a focus will be used including the frequently encountered clinical scenarios and the specific questions from the surgeons, frequent diagnostic considerations and their major diagnostic criteria with associated diagnostic pearls, artifacts and pitfalls and how to avoid them. Common and practical problems including reactive atypia versus carcinoma in salivary glands, resection margins in tongue and laryngectomy specimens, small blue cell tumors in the base of the skull, a primary lesion versus a metastatic squamous carcinoma in the neck, etc. will be illustrated with color pictures and accompanied legend. As a handbook for practicing pathologists, this book will be an indispensable aid to diagnosis and avoiding dangers in one of the most challenging situations that pathologists encounter.

Frozen section of Neuropathology-related cases is performed while the patient is undergoing surgery. Intraoperative consultation is used to help guide intraoperative management of the case and to ensure that adequate and appropriate tissue has been obtained for purposes of making an accurate final diagnosis. Frozen section diagnosis is often a highly demanding situation for the pathologist, who must render a diagnosis quickly and provide sound guidance and advice. In addition to the need for rapid recall of differential diagnoses, there are many pitfalls and artifacts that add to the risk of frozen section diagnosis that are not present with permanent sections of fully processed tissue that can be examined in a more leisurely fashion. Most standard pathology textbooks focus primarily on permanent section material and largely ignore the topic of frozen section.The purpose of this volume is to add to the Frozen Section Library series and provide a convenient, user friendly handbook to assist in the evaluation of central nervous system related frozen sections. It provides a useful reference, organized around differential diagnoses, primarily by location in the central nervous system. The text will be illustrated with color pictures and include tables as appropriate. This text provides a valuable tool for the practicing surgical pathologist both in community and in academic centers as well as pathology residents and fellows in training when confronted with Neuropathology frozen section.
