Tumoral calcinosis in scleroderma.

I Katayama, K Higashi, H Mukai

    The Journal of Dermatology
    |February 1, 1989
    PubMed
    Summary

    Tumoral calcinosis developed in a patient with scleroderma and Sjögren's syndrome. This condition involved cystic tumors secondary to connective tissue degeneration, a potential complication of these autoimmune diseases.

    Area of Science:

    • Rheumatology
    • Pathology
    • Dermatology

    Background:

    • Scleroderma and Sjögren's syndrome are autoimmune diseases affecting connective tissues.
    • Tumoral calcinosis is characterized by calcium salt deposits in soft tissues.

    Observation:

    • A 36-year-old female patient with scleroderma/Sjögren's syndrome presented with multiple cystic tumors on her left hand, right elbow, and left shoulder joint.
    • Histological examination revealed amorphous eosinophilic substances in subcutaneous tissue with positive PTAH, rosindole, and focal Von Kossa staining.
    • Tumoral lesions discharged rheumatoid rice body-like substances with chalky fluid.

    Findings:

    • The patient was diagnosed with tumoral calcinosis.
    • The condition was deemed secondary to connective tissue degeneration associated with scleroderma/Sjögren's syndrome.

    Implications:

    • This case highlights a rare manifestation of tumoral calcinosis secondary to autoimmune connective tissue diseases.
    • Understanding this association may improve diagnosis and management of similar cases.
    • Further research into the pathogenetic mechanisms linking autoimmune diseases and tumoral calcinosis is warranted.
