title: [Salmon-pink colored conjunctival tumor with amyloid deposits].
abstract: An 82-year-old male patient presented with a salmon-pink colored conjunctival tumor of the left eye. A circumscribed, dense and whitish portion was detected by clinical examination. The histophological and immunhistochemical examination of the biopsy tissue revealed a CD20+ marginal zone lymphoma of the conjunctiva with amyloid deposits. Extranodal marginal zone lymphoma at this site is the most common lymphoma of the ocular adnexa and accounts for 5-10% of malignant diseases. An association with amyloid production is very rare and according to the current state of knowledge has no known impact on the outcome.
