title: Acute lymphoblastic leukemia manifesting in an adult as a conjunctival mass.
abstract: OBJECTIVE
  To describe the clinical manifestation and course of disseminated acute lymphoblastic leukemia in an adult.
  
  
  METHODS
  Case report. Recurrence of disseminated disease was heralded by "salmon patch" involvement of the conjunctiva. The ocular tumor was treated successfully with external beam radiotherapy.
  
  
  RESULTS
  The patient, who had a history of T-cell acute lymphoblastic leukemia, had recurrent disease involving the left eye conjunctiva. The diagnosis was confirmed by histopathologic analysis.
  
  
  CONCLUSIONS
  Although acute lymphoblastic leukemia typically occurs in children, the tumor can masquerade as a conjunctival lymphoma in adults.
