Abstract
PURPOSE
To describe a case of a patient with bilateral proliferation of chondrocytes of the lower palpebral conjunctiva.
METHODS
Observational case report and review of relevant literature.
RESULTS
Conjunctival biopsy from an 83-year-old man with bilateral acquired lower conjunctival nodules revealed a benign proliferation of chondrocytes. A general medical evaluation revealed serum monoclonal gammopathy with light-chain proteinuria.
CONCLUSIONS
Bilateral-acquired benign chondrocyte tumefactions of the palpebral conjunctiva have not been previously reported. This initiated a search for a biologically plausible explanation. The findings in this report support that these proliferations represent chondroid metaplasia related to light-chain deposition. The diagnosis requires exclusion of other forms of chondrocyte proliferation including well-differentiated chondrosarcoma.
