Nodular scleroderma and pleomorphic acid-fast bacteria

A R Cantwell, L Rowe, D W Kelso

    Archives of Dermatology
    |November 1, 1980
    PubMed
    Summary

    This study found rare acid-fast bacteria in scleroderma nodules, suggesting a potential microbial link to this rare skin condition. Further research is needed to confirm bacteria

    Area of Science:

    • Dermatology
    • Microbiology
    • Pathology

    Background:

    • Scleroderma is a rare connective tissue disease characterized by hardening and tightening of the skin.
    • A rare variant of scleroderma presents with multiple, elevated dermal nodules.
    • The etiology of scleroderma remains largely unknown, with ongoing research into potential contributing factors.

    Observation:

    • Histologic examination of dermal nodules revealed rare acid-fast bacteria and non-acid-fast coccoid forms.
    • Skin cultures from nodules yielded intermittently acid-fast coccobacilli and non-acid-fast cocci (Staphylococcus epidermidis).

    Findings:

    • The presence of pleomorphic, acid-fast bacteria in scleroderma lesions is reconfirmed.
    • Observed microbial forms may represent cell-wall-deficient L-forms or unusual mycobacterial growth variants.

    Implications:

    • These findings suggest a potential role for bacteria in the pathogenesis of this rare scleroderma variant.
    • Further investigation into microbial presence in skin cultures and histology may elucidate the role of bacteria in scleroderma.
    • This research opens avenues for exploring novel diagnostic and therapeutic strategies targeting potential microbial agents.
