Farber's disease: a fine structural study.

P Abenoza, R K Sibley

    Ultrastructural Pathology
    |January 1, 1987
    PubMed
    Summary
    This summary is machine-generated.

    Farber's disease, a rare metabolic disorder, was diagnosed in an infant presenting with enlarged organs and distinctive facial features. Diagnosis was confirmed by identifying specific cellular structures and a deficiency in lysosomal acid ceramidase.

    Area of Science:

    • Biochemistry
    • Pediatrics
    • Genetics

    Background:

    • Metabolic storage diseases present a diagnostic challenge in neonates.
    • Early identification is crucial for managing rare genetic disorders.

    Observation:

    • A 1-week-old infant exhibited hepatosplenomegaly, coarse facial features, and cloudy corneas.
    • Kupffer cells in liver biopsy showed enlarged, foamy cytoplasm.
    • Skin biopsy revealed no abnormalities by light microscopy.

    Findings:

    • Ultrastructural analysis of skin and liver identified characteristic curvilinear bodies, 'banana' shapes, and concentric lamellar structures.
    • These ultrastructural findings were consistent with Farber's disease.
    • Biochemical assays confirmed a deficiency of lysosomal acid ceramidase in cultured fibroblasts and liver tissue.

    Implications:

    • This case highlights the importance of integrating ultrastructural and biochemical analyses for diagnosing lysosomal storage diseases.
    • Accurate diagnosis of Farber's disease enables appropriate patient management and genetic counseling.
    • Further research into lysosomal acid ceramidase deficiencies can improve understanding and treatment strategies.
