| Observation | |
| Pathology | Pathology: A low grade infection, usually staphylococcal, enters through a duct of the Meibomian gland. As a result, there is infiltration of the wall of the duct with leucocytes as well as proliferation of the epithelium of the duct. Thus the ducts gets blocked and Meibomian secretions accumulates and causes enlargement of the gland. The secretion acts as irritant and causes inflammation and granuloma formation. |
