Generalized aspergillosis showing a granulomatous pattern.

I Sugawara, T Shimamine, M Okudaira

    Acta Pathologica Japonica
    |September 1, 1979
    PubMed
    Summary

    This autopsy revealed a rare case of generalized aspergillosis mimicking sarcoidosis. The fungal infection presented with granulomatous inflammation in multiple organs, challenging diagnosis.

    Area of Science:

    • Pathology
    • Mycology
    • Immunology

    Background:

    • Presents an autopsy case of a rare generalized aspergillosis.
    • Highlights a prominent granulomatous pattern that simulated sarcoidosis.
    • Details the clinical course of a 40-year-old Japanese female over four years.

    Observation:

    • Kveim's test was positive.
    • Multiple epithelioid cell granulomata, necrotizing, and suppurative lesions were observed.
    • Affected organs included generalized lymph nodes, liver, epicardium, gallbladder, adrenals, kidneys, and duodenal mucosa.

    Findings:

    • Fungal elements identified as Aspergillus using fluorescent antibody technique (indirect method).
    • Fungal elements were present within epithelioid cell granulomata and necrotizing lesions.
    • No predisposing factors such as underlying disease or immunodeficiency were identified.

    Implications:

    • This case underscores the importance of considering fungal infections in differential diagnoses, especially when granulomatous patterns are present.
    • Highlights the diagnostic challenge posed by Aspergillus infections that mimic other granulomatous diseases like sarcoidosis.
    • Emphasizes the utility of specialized techniques like fluorescent antibody testing for accurate fungal identification in complex autopsy cases.
