Pseudorheumatoid nodule involving the orbit. 1982

B B Floyd, and B Brown, and H Isaacs, and D S Minckler

We report a clinicopathologic study of an unusual case of pseudorheumatoid nodule involving the right orbit of a child. Pathologically, the orbital lesion was similar to subcutanous nodules of rheumatoid arthritis and rheumatic fever. The physical findings and laboratory studies in our case did not reveal any evidence of systemic disease. Based on a review of reported cases involving other locations, this lesion appears clinically benign in children.
