Lacrimal sac tumour presenting with blood-stained ocular discharge

Malignant epithelial tumours of the lacrimal sac are uncommon. They can mimic chronic dacryocystitis or dacryostenosis to cause a delay in diagnosis. The presence of a medial canthal lump with blood-stained ocular discharge should arouse the suspicion of this diagnosis. The prognosis of lacrimal sac tumour is often guarded especially following tumour recurrence after incomplete resection. We report a patient with squamous cell carcinoma of the lacrimal sac to highlight its presentation and clinical course.
