Rapid frozen section in pediatric pathology.

H S Preston, P M Bale

    The American Journal of Surgical Pathology
    |August 1, 1985
    PubMed
    Summary

    Pediatric frozen section analysis presents unique challenges, particularly with undifferentiated small-cell cancers and congenital disorders. Despite diagnostic difficulties, accuracy remains high for specific conditions like Hirschsprung

    Area of Science:

    • Pediatric Pathology
    • Surgical Pathology
    • Diagnostic Accuracy

    Background:

    • Frozen section examination in pediatric practice differs significantly from adult practice.
    • Key challenges include diagnosing undifferentiated small-cell cancers and assessing congenital disorders.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy and challenges of frozen section examinations in pediatric surgical pathology.
    • To identify specific areas of difficulty and success in pediatric frozen section diagnoses.

    Main Methods:

    • Analysis of 520 pediatric frozen section cases.
    • Review of diagnostic outcomes, including deferred and inaccurate diagnoses.
    • Categorization of cases by specimen type (e.g., nervous system, soft tissue, bone) and clinical indication (e.g., Hirschsprung's disease, biliary atresia).

    Main Results:

    • Overall incidence of deferred diagnoses was 5.6%, and inaccurate diagnoses was 3.5%.
    • Diagnostic challenges were noted in differentiating small-cell cancers and in nervous system neoplasms (e.g., ependymoma vs. medulloblastoma).
    • 100% accuracy was achieved in detecting ganglion cells for Hirschsprung's disease; challenges existed in identifying bile ducts in biliary atresia.

    Conclusions:

    • Pediatric frozen sections have a notable rate of diagnostic challenges, especially with small-cell cancers.
    • Accurate diagnosis often requires integrated clinical and radiological information.
    • Specific congenital conditions, like Hirschsprung's disease, demonstrate high diagnostic accuracy with frozen section analysis.
