Congenital microvillous atrophy: specific diagnostic features.

A D Phillips, P Jenkins, F Raafat

    Archives of Disease in Childhood
    |February 1, 1985
    PubMed
    Summary

    Electron microscopy revealed microvillous involutions in the small and large bowel of infants with intractable diarrhea. This finding suggests congenital microvillous atrophy, a severe condition.

    Area of Science:

    • Pediatric Gastroenterology
    • Cell Biology
    • Histopathology

    Background:

    • Intractable diarrhea of infancy syndrome presents a significant clinical challenge.
    • Accurate diagnosis is crucial for appropriate management and prognosis.

    Observation:

    • Electron microscopy was utilized to examine mucosal biopsies from two infants with intractable diarrhea.
    • Biopsies were taken from both the proximal small intestine and the colon.

    Findings:

    • Distinct microvillous involutions were identified in the small and large bowel mucosa of both patients.
    • This ultrastructural finding is proposed as a specific diagnostic marker.

    Implications:

    • The presence of microvillous involutions may indicate congenital microvillous atrophy.
    • Congenital microvillous atrophy is a distinct, severe disorder within intractable diarrhea syndromes.
    • Early identification of this specific condition is critical due to its extremely poor prognosis.
