—An immunohistochemical analysis of conjunctival biopsy specimens from monkeys inoculated with Chlamydia trachomatis has shown a large number of Tsuppressor/cytotoxic and T-helper cells.1 In light of this modulation of cell-mediated immunity by C trachomatis, we recently had the opportunity to study a patient who had carcinoma in situ of the limbus together with a history and physical findings of healed trachoma.
Report of a Case.

As a child she had trachoma that resulted in several surgical procedures for correction of entropion/trichiasis. Her medical history also included hypertension, asthma, and a seizure disorder.

The superior tarsal conjunctivae displayed Arlt's lines. Additionally, the left upper tarsus was foreshortened. The superotemporal
