Summary
This study reports the first case of IgG4-related disease affecting the lacrimal sac. Early diagnosis of this IgG4-related eye condition is crucial for effective corticosteroid treatment.
Area of Science:
- Ophthalmology
- Immunology
- Pathology
Background:
- Immunoglobulin G4 (IgG4)-related disease is a recently identified systemic condition.
- Ocular adnexal involvement, including dacryoadenitis and orbital disease, is recognized.
- Prompt diagnosis is vital as acute phases respond well to corticosteroid therapy.
Observation:
- An 80-year-old female presented with a painless, erythematous, indurated swelling of the right lacrimal sac.
- Complete obstruction of the right nasolacrimal system and a 9-mm lacrimal sac mass were identified.
- Elevated serum IgG4 levels and characteristic lacrimal sac histology confirmed the diagnosis.
Findings:
- This case represents the first documented instance of IgG4-related disease specifically involving the lacrimal sac.
- Histopathological examination confirmed IgG4-related disease.
- The patient declined corticosteroid treatment and was monitored for disease progression and potential malignancy.
Implications:
- This finding expands the spectrum of IgG4-related ocular adnexal disease.
- Highlights the importance of considering IgG4-related disease in lacrimal sac pathology.
- Emphasizes the need for vigilant monitoring in cases where treatment is declined.
