Frozen Section versus Gross Examination for Bone Marrow Margin Assessment During Sarcoma Resection

Examination of Bone Marrow

The immunologic phenotyping of bone marrow biopsies and aspirates: frozen section techniques.

Techniques were developed for the preparation of frozen sections from undecalcified bone marrow biopsy cores and bone marrow aspirates. Selected indirect antibody and biotin-avidin detection systems, employing immunoperoxidase or immunofluorescent labels, were studied to determine which were best suited for bone marrow frozen section immunohistopathology. Methods employing murine hybridoma mono...

Imprint cytology versus frozen section analysis for intraoperative assessment of sentinel lymph node in breast cancer

INTRODUCTION Sentinel lymph node (SLN) biopsy is the gold standard for surgical staging of the axilla in breast cancer (BC). Frozen section (FS) remains the most popular means of intraoperative SLN diagnosis. Imprint cytology (IC) has also been suggested as a less expensive and equally accurate alternative to FS. The aim of our study was to perform a direct comparison between IC and FS on the s...

Parathyroid Autotransplantation During ThyroidectomyIs Frozen Section Necessary?

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...

Use of Intraoperative Frozen Section during Mediastinoscopy

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...
