title: [Conjunctival marginal zone lymphoma: clinical and pathological features].
abstract: OBJECTIVE
  We present the case of a 66-years-old woman with a left pink-coloured tumor in the temporal bulbar conjunctiva which had been present for 7 months, without response to the topic treatment applied. A biopsy and an immunohistochemistry study were done to confirm the diagnosis.
  
  
  CONCLUSIONS
  The biopsy showed a low-grade B-lymphoma compatible with a marginal zone lymphoma, formerly called <<mucous-associated lymphoid tissue>> (MALT) lymphoma. The conjunctival Iymphomas are rare and the majority of them are marginal zone lymphomas. It is important to differentiate this one from another ocular adnexa lymphomas, because of their low grade of association to extraocular affectation and more favourable prognosis.
