This is a practical review of intraoperative consultations in neuropathology. The idea of intraoperative consultation, its philosophy, use, and expectations of the surgeon and the pathologist alike, are discussed, as well as the techniques used to perform this function. Later, the practical cytologic and histologic/frozen section features of major neuropathological entities, which are commonly ...

Background In recent years, Japan has been short of pathologists. There are about 2,000 board-certified pathologists against 130 million people. Most pathologists are working in the urban area and only few are available in rural regions. Telepathology in Japan developed under these circumstances, mainly for intraoperative frozen section diagnosis where no pathologist is available. We have been ...

INTRODUCTION The aim of the study was to evaluate the clinical usefulness of a one-step nucleic acid amplification assay (OSNA) for intraoperative detection of metastases to sentinel lymph nodes (SLNs) in comparison to examination of frozen sections, and to summarize the results of previous studies. MATERIAL AND METHODS We enrolled 98 patients aged 58.13 ±10.74 years treated surgically for br...

BACKGROUND Maximisation of the potential of sentinel lymph node biopsy as a minimally invasive method of axillary staging requires sensitive intraoperative pathological analysis so that rates of re-operation for lymphatic metastases are minimised. The aim of this study was to describe the test parameters of the frozen section evaluation of sentinel node biopsy for breast cancer compared to the ...

Angiosarcoma of the ovary is rare but represents an aggressive type of malignant ovarian neoplasms. The purpose of this report is to describe the features of angiosarcoma arising in mucinous tumor that was misinterpreted as a benign vascular proliferation during the intraoperative consultation. A 45-year-old woman presented with an abdominal mass for 1 month. Exploratory laparotomy was performe...

BACKGROUND The purpose of this study was to investigate the outcomes of patients with papillary thyroid cancer (PTC) with lateral neck metastasis according to their permanent pathology report but negative frozen section findings who did not undergo lateral neck dissection. METHODS Between September 2009 and December 2011, 575 patients at Gangnam Severance Hospital (Seoul, Korea) underwent fro...

OBJECTIVE To evaluate the intraoperative imprint diagnoses of smears from sentinel lymph nodes that had been primary screened by cytotechnologists and to assess the most important causes of false negative (FN) imprint diagnoses. STUDY DESIGN Material consisted of 429 imprints from sentinel lymph nodes in 211 breast cancer patients that were sent for frozen section examination over 13 months. ...

PURPOSE Intraoperative frozen-section analysis of the lumpect-omy margin during breast-conserving surgery (BCS) is an excellent method in obtaining a clear resection margin. This study aimed to investigate the usefulness of intraoperative circumferential frozen-section analysis (IOCFS) of lumpectomy margin during BCS for breast cancer, and to find factors that increase the conversion into maste...
