Chalazion

A Chalazion (also known as Meibomian Cyst) appears as a lump on the eyelid

The condition typically presents as an inflamed swelling in the eyelid caused by a blocked oil duct (meibomian gland)

Very rarely, a chalazion may masquerade and in fact be a tumour called a meibomian gland carcinoma or sebaceous cell carcinoma, particularly if the chalazion doesn’t go away with incision and curettage surgery or appears solid at surgery, in which case a biopsy is taken.

chalazion has a typical “grey” appearance on the underside of the eyelid which helps to confirm the diagnosis
