• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Conjunctival involvement can be a presenting sign of orbital or ocular adnexal lymphoma, and the patches described as salmon-colored are a classic appearance. When lymphoma infiltrates the conjunctiva, it can create flat, pink-to-salmon colored patches rather than a typical red inflammatory conjunc­tivitis. These patches are often painless and may be unilateral, sometimes enlarging slowly, which helps distinguish them from acute infections or irritative conjunctivitis.

Most orbital/adnexal lymphomas are of the MALT (mucosa-associated lymphoid tissue) type, and the conjunctiva is a possible site of involvement. Because the appearance can mimic benign conjunctival processes or other inflammatory conditions, persistent salmon patches in adults should raise suspicion and lead to biopsy for definitive diagnosis and staging.
