T-cell lymphoblastic lymphoma of Tenon's capsule: an unusual presentation.

Lymphoid neoplasms of the orbit account for approximately 6-8 % of all orbital tumors and 15 % of all ocular adnexal tumors. We report an unusual case of T-cell lymphoblastic lymphoma occurring in a 30-year-old man, presenting as red, painless, firm swelling in the Tenon's capsule of the eye.
