PURPOSE: To report a rare case of large conjunctival B-cell lymphoma in a child. METHODS: A 13-year-old girl was initially diagnosed with a right lower eyelid chalazion. After 3 weeks during which the mass was growing, she was referred for treatment to our department. Because of the unusual appearance of the mass, an excisional biopsy was performed. RESULTS: Pathological findings were consistent with those of a large B-cell lymphoma. CD20 and Ki67 staining were positive, and polymerase chain reaction analysis showed monoclonality of B cells. CONCLUSIONS: Although conjunctival lymphoma is a very rare entity in children, it should be included in the differential diagnosis of an eyelid or conjunctival mass.
