Biopsia por congelación

Frozen section biopsy is a method used for intraoperative consultation because results are rapidly obtained, enables the differentiation between a benign and malignant lesion and the analysis of resection margins, helps with the diagnosis of some neoplasms with a diagnostic accuracy of 90%. Nevertheless, frozen biopsy has several limitations, such as cytological and architectural distortion, artifacts, and its low performance in some specific neoplasms, which explain why frozen section biopsy is a tool for patient care that does not replace the conventional biopsy. The aim of this module is to review the clinical utility and the disadvantages of frozen section biopsy in specimens from the female genital tract, kidney, bladder, gastrointestinal tract, peritoneum, liver, gallbladder, pancreas and skin. Additionally, a brief description of the technique and differences with conventional biopsy are included.
