title: Pseudorheumatoid nodules of the ocular adnexa.
abstract: A clinicopathologic study of 21 cases revealed pseudorheumatoid subcutaneous nodules occurring in the eyelids and periorbital region of children and young adults. These nodules were most frequently located in the lateral upper eyelids and outer canthal region, and in five cases they were multiple. The lesions recurred in about 20% of the cases. In addition, new lesions located elsewhere were observed in 26% of cases. Histopathologically they resembled the subcutaneous nodules of rheumatoid arthritis and rheumatic fever. Follow-up information on 15 patients (from two to 12 years) and the results of laboratory studies on seven patients had failed to reveal any association with these two systemic diseases. Pseudorheumatoid nodules may be indicated when a healthy child or a young adult presents with solitary or multiple subcutaneous nodules, especially in the eyelids. These lesions pursued a benign clinical course and local excision, which is usually performed for diagnostic purposes, was the only treatment indicated. The lesions had a tendency to regress spontaneously; therefore, local recurrences should be treated conservatively by periodic follow-up examinations.
