    This study details an unusual orbital pseudorheumatoid nodule in a child. The lesion, pathologically similar to rheumatoid nodules, showed no signs of systemic disease and appears benign in pediatric cases.

    Area of Science:

    • Ophthalmology
    • Pediatric Pathology
    • Rheumatology

    Background:

    • Pseudorheumatoid nodules are rare soft tissue masses.
    • Orbital involvement is exceptionally uncommon, particularly in pediatric patients.
    • Distinguishing these nodules from other orbital masses is crucial for appropriate management.

    Observation:

    • A child presented with an unusual lesion involving the right orbit.
    • Pathologic examination revealed features similar to subcutaneous rheumatoid nodules.
    • Clinical and laboratory evaluations did not indicate any underlying systemic rheumatic disease.

    Findings:

    • The orbital pseudorheumatoid nodule exhibited histopathological characteristics consistent with rheumatoid arthritis and rheumatic fever nodules.
    • Despite the nodular appearance, the patient showed no systemic signs of inflammatory or autoimmune disease.

  • Review of similar extra-articular cases suggests a benign clinical course in children.

    • Implications:

    • This case expands the known locations for pseudorheumatoid nodules.
    • It highlights the importance of considering benign orbital lesions in children presenting with masses.
    • Further research may clarify the pathogenesis and long-term prognosis of pediatric orbital pseudorheumatoid nodules.
