AGUILAR JARAMILLO, Andrés Manuel et al. IgG4-Associated Ocular Inflammatory Pseudotumor. A Case Report. Rev. Fac. Med. (Méx.) [online]. 2023, vol.66, n.6, pp.17-21. Epub 01-Mar-2024. ISSN 2448-4865. https://doi.org/10.22201/fm.24484865e.2023.66.6.03.
Introduction:
IgG4-associated ocular inflammatory pseudotumor is a rare, non-neoplastic inflammatory process with an incidence of 0.28-1.08 per 100,000 people. The diagnosis of this pathology is one of exclusion, having to meet histopathological criteria, enlargement of a specific organ, and serious concentrations of IgG4. Treatment aims to avoid secondary complications.
Clinical case:
A 54-year-old woman with no previous reported pathologies, reports that for the past 6 months she has itching at the level of the eyeball and the left eyelid, suddenly and without apparent cause, in addition to decreased visual acuity and retro-ocular pain; this is why she asked for the evaluation. The physical examination revealed normal eye movements, left proptosis, pain on palpation, subconjunctival hyperemia, corneal opacity, absence of red reflex, and the left eye being more resistant to pressure in relation to the contralateral eye. The cranio-thoraco-abdominal tomography reported images at the left ocular level that were suggestive of choroidal melanoma without findings of metastatic activity. Enucleation of the left eye was performed. The specimen was sent to pathology which reported diffuse lymphoplasmacytic infiltrate positive for IgG4.
Conclusion:
Ocular IgG4 disease is a very rare pathology with non-specific symptoms and complex diagnosis. However, a quick and correct approach is essential to avoid complications.
