Subcutaneous granuloma annulare("pseudorheumatoid nodule") of the eyebrow.
Subcutaneous granuloma annulare occurs either as a single or multiple lesion. When the ocular adnexa are involved, the lateral aspect of the eyelid and the lateral canthus are sites of predilection. These lesions occur chiefly in children and only rarely in adults. They have the same clinical (and histopathological) appearance as rheumatoid nodules and are, therefore, also known as "pseudorheumatoid nodules." Despite this similarity, these nodules are isolated lesions and are not related to systemic disease, including rheumatoid arthritis and rheumatic fever. The presently reported case exemplifies the characteristic clinical and pathological features of this disorder.
