BACKGROUND Despite extensive investigations some patients with suspected lung cancer may undergo thoracotomy without preoperative histological proof of malignancy. A questionnaire on the use of histological examination of peroperative frozen sections in such patients was sent to 50 thoracic surgeons. Replies were received from 41 surgeons and indicated an absence of consensus on the usefulness ...

Introduction: Staging of mediastinal lymph nodes (MLN) by mediastinoscopy can be of critical importance in assessing candidacy for lung resection. Mediastinoscopy is often performed as a sole procedure, with permanent pathology results guiding subsequent intervention. Our practice has been to perform mediastinoscopy followed by immediate surgical resection, as indicated, based on intraoperative...

Results: Of 179 attempted autotransplantations of parathyroid glands, parathyroid tissue was confirmed in 167 biopsy specimens (93.3%). Incorrect identification of parathyroid gland occurred in 12 instances. The tissue mistaken as parathyroid gland included fat in 6 cases, thyroid tissue in 4 cases, lymph node in 1 case, and thymus in 1 case. Transplantation of at least 1 parathyroid gland (ran...

BACKGROUND Pre-transplant frozen section evaluation for macrovesicular steatosis has long been used as a guide for donor liver utility, but may not agree with the permanent section evaluation. This study sought to evaluate the accuracy of frozen section in an active transplant service. METHODS Retrospective review of cases where frozen section analysis was undertaken to assess percent macrove...

BACKGROUND Surgical excision of the primary tumor with safe margins remains the mainstay of treatment for oral cavity squamous cell carcinoma (OSCC). The standard of care for assessment of intraoperative margins is frozen section histopathology. Unfortunately the facility is not available at most centers in limited resource countries. Toluidine blue, a metachromatic dye, has been well described...

BACKGROUND Sentinel node (SN) biopsy is the standard of care for the assessment of axilla in early breast cancer patients with clinically node negative disease. Confirmed absence of tumour deposit in node on intra operative frozen section (FS) examination saves the patient from complete axillary dissection. However controversies arise when inconsistencies occur in results of frozen and permanen...

Aim: Frozen section is a highly accurate and useful procedure wherein knowledge of the clinical presentation, good rapport with the operating surgeon, pathologist’s experience and in depth knowledge of the subject, awareness of the limitations of the procedure, ability to provide a rapid and reliable diagnosis under pressure are of great importance. The correlation between intra operative froze...

BACKGROUND Epithelial ovarian neoplasms are an important cause of morbidity and mortality in women. The surgical management of ovarian neoplasms depends on their correct categorization as benign, borderline or malignant. This study was undertaken to evaluate the accuracy of intra-operative frozen section in the diagnosis of various categories of ovarian neoplasms. METHODS Intraoperative froze...

OBJECTIVE To evaluate the accuracy of frozen section tests at different anatomical sites performed in an academic department of pathology. METHODS We conducted a retrospective study from a computerized database of all frozen section tests. These diagnoses were compared to definite paraffin, used as controls. The tests were divided into three groups: inconclusive, consistent and inconsistent, ...

Objective. To describe the usefulness of intraoperative frozen section in the diagnosis and treatment of thyroid nodules where fine needle aspirate biopsies have evidence of follicular neoplasm. Study Design. Retrospective case series. Methods. All patients have a fine needle aspirate biopsy, an intraoperative frozen section, and final pathology performed on a thyroid nodule after initiation of...
