Conjunctival lymphoma masquerading as chronic conjunctivitis.

OBJECTIVE

Malignant lesions of the conjunctiva may present with slowly evolving signs resembling inflammation. The authors describe the clinical and histopathologic findings of two patients with bilateral conjunctival lymphoma who presented with a history of chronic conjunctivitis without clinically noticeable subconjunctival nodules.

DESIGN

Case report.

PARTICIPANTS

Two patients.

INTERVENTION: Both patients underwent conjunctival biopsy for evaluation of persistent conjunctival inflammation that did not respond to various medical treatment methods.

RESULTS

Histopathologic examination revealed extranodal marginal zone B-cell lymphoma (mucosa-associated lymphoid tissue type) in one patient and follicle center lymphoma in the other patient. Both patients subsequently received radiation therapy and achieved a complete remission with no evidence of recurrence in the follow-up period of 20 and 16 months, respectively.

CONCLUSIONS

Conjunctival lymphoma should be included in the differential diagnoses of chronic conjunctivitis. Persisting signs and symptoms of conjunctivitis not responding to standard treatment should prompt biopsy.
