Case Study: April 2011


An 80 year old man presented with an intermittent painless lump on the inner corner of his left eye associated with watering. He had a history of chronic bronchitis and congestive cardiac failure. Examination showed a 2 cm cystic swelling that caused retrograde regurgitation of mucoid fluid on pressure over the lacrimal sac from the lacrimal puncta. Lacrimal syringing showed mucoid regurgitation consistent with nasolacrimal duct obstruction. The patient opted for a dacrycystectomy. Prior to the planned surgery, he presented with an acute dacryocystitis with complete resolution of the symptoms after antibiotics. He subsequently underwent uncomplicated dacryocystectomy . The entire sac was sent for histopathological assessment.

  1. This shows the mucosa of the lacrimal sac with an acute inflammatory reaction.
  2. A circumferential atypical lymphoid infiltrate.
  3. CD20
  4. B-cell non-Hodgkin’s lymphoma. The B cells were negative for CD5, Cd10, Cyclin D1 and CD23. The subtype is extranodal marginal zone lymphoma of MALT type (MALToma-WHO classification) of the lacrimal sac.
