ABSTRACT
The eye responds to an irritant by forming a discharge of mucus. The irritant may be an infectious agent, a foreign body, or simply a dry cornea related to exposure or lack of tear production. However, an eyelid malignancy, such as basal cell, squamous cell, or sebaceous cell carcinoma which involves the mucocutaneous junction, can act as an irritant and give rise to a constant mucoid discharge.
