Summary
Pseudorheumatoid nodules, rare in adults, are necrobiotic granulomas histopathologically similar to other conditions. This study confirms their presence in the episclera and orbit, alongside eyelid and eyebrow involvement.
Area of Science:
- Ophthalmology
- Dermatology
- Rheumatology
Background:
- Pseudorheumatoid nodules are subcutaneous necrobiotic granulomas.
- They share histopathologic features with rheumatoid arthritis, granuloma annulare, necrobiosis lipoidica diabeticorum, and systemic lupus erythematosus.
- While common in children, they occur in adults, typically on extremities and scalp.
Observation:
- Eyelid and eyebrow involvement is infrequent.
- This case report details histopathologic verification of episcleral and orbital pseudorheumatoid nodules in an adult.
- The adult patient also presented with eyelid and eyebrow nodules.
Findings:
- Confirmed episcleral and orbital pseudorheumatoid nodules in an adult.
- Demonstrated histopathologic similarity to known necrobiotic granulomas.
- Highlighted infrequent ocular and periocular presentation.
Implications:
- Pseudorheumatoid nodules should be considered in the differential diagnosis of subconjunctival mass lesions.
- This expands the known clinical spectrum of pseudorheumatoid nodules.
- Emphasizes the importance of considering systemic conditions in periocular lesions.
