This 79 year old male presents with a chronic discharge from his upper eyelid. There is minimal swelling, and the discharge is unresponsive to antibiotics.
On eversion, a discharging mass was noted.
This is how it turned out….a very unusual chalazion sac, an inpouching of epithelium into the structure of the tarsus.
The important thing here is to exclude sebaceous gland carcinoma.
Definitive treatment would require complete excision of the sac. At present, he is happy and I have warned him it is likely to recur.
