title: Localized conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma is amenable to local chemotherapy.
abstract: OBJECTIVE
  Conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma is a rare, low-grade, non-Hodgkin's B-cell lymphoma. We report our successful management of localized conjunctival MALT lymphoma with topical Mitomycin C (MMC).
  
  
  METHODS
  This is a case report. A 35-year-old woman had a mobile painless 1.5x1-cm mass in the left conjunctiva for 2 years. Examination revealed two similar masses in the right conjunctiva. Incisional biopsy for immunohistochemical stain and PCR of the left conjunctival mass showed MALT lymphoma. She was given four courses of topical 0.04% MMC eyedrops. There was transient conjunctival injection and superficial punctate keratopathy which responded to topical steroid and lubricant.
  
  
  RESULTS
  The lesions regressed completely after the fourth cycle of treatment and repeat biopsy confirmed complete remission.
  
  
  CONCLUSIONS
  This is the first report of localized conjunctival MALT lymphoma being successfully treated by topical MMC with minimal local controllable side effects.
