2. Introduction
Childhood conjunctival lymphoma is an extremely rare entity and may comprise a diagnostic challenge
We report a case of childhood conjunctival lymphoma masquerading as an internal chalazion.

3. Case report
A 13-year-old girl was referred to our department with a three weeks history of right lower lid forniceal mass, initially diagnosed as a chalazion

4. Case report
On examination, a 15 millimeter elevated pink conjunctival mass was apparent in her lower fornix. The mass was surgery excised.

5. Case report
Figure 2A. Groups of cells containing large nuclei with scarce cytoplasm (arrow) and nucleoli (arrowhead), positive for CD20 and Ki67 staining (2B, 2C).

6. Case report
Polymerase chain reaction analysis of the immunoglobulin heavy chain gene rearrangement showed monoclonality of B-cells.
The results were compatible with large B cell lymphoma.

7. 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
