    Summary

    Soft tissue calcification is common in some autoimmune diseases. This study details four cases of calcification in patients with systemic lupus erythematosus (SLE), highlighting its varied presentation.

    Area of Science:

    • Rheumatology
    • Autoimmune Diseases
    • Medical Imaging

    Background:

    • Soft tissue calcification is a known complication in progressive systemic sclerosis and dermatomyositis.
    • Reports of calcification in systemic lupus erythematosus (SLE) are rare, with only seven cases previously documented.
    • Understanding calcification patterns in SLE is crucial for accurate diagnosis and management.

    Purpose of the Study:

    • To report and characterize soft tissue calcification in patients diagnosed with systemic lupus erythematosus (SLE).
    • To analyze the pattern and location of calcification in SLE patients.
    • To compare the presentation of calcification in SLE with other connective tissue diseases.

    Main Methods:

    • Case series methodology.
    • Review of medical records for four patients with confirmed SLE.
    • Analysis of imaging studies (e.g., X-ray, CT) and histopathology reports detailing calcification.
    • Clinical assessment of affected tissues (subcutaneous, muscle, periarticular).

    Main Results:

    • Four patients with well-documented SLE were identified with soft tissue calcification.
    • Calcification occurred in subcutaneous tissues, muscles, and/or periarticular structures.
    • The observed patterns and locations of calcification in SLE patients mimicked those typically seen in other rheumatic disorders.

    Conclusions:

    • Soft tissue calcification can occur in systemic lupus erythematosus (SLE), though infrequently reported.
    • The presentation of calcification in SLE is diverse and can resemble other conditions.
    • Increased awareness and reporting of SLE-associated calcification are warranted for improved clinical recognition.
