Chalazion is a chronic inflammatory granuloma of meibomian gland, which is formed on the basis of the blockage of meibomian gland discharge pipeline and secretion retention. Also called meibomian gland cyst. This is a common disease that can affect children and adults.

The disease progresses slowly and can occur repeatedly. Hard lumps can be touched on the eyelids, but there is no pain, and the surface skin bulges. The disease is a common disease, which can occur at all ages. It should be differentiated from meibomian adenocarcinoma when it tends to recur.

Clinical manifestations:

1, the course of disease is slow, generally no obvious symptoms, no pain in the eyes, and sometimes only a heavy feeling, which may cause temporary astigmatism due to tumor compression, or foreign body sensation due to tumor compression on the eyeball.

2. One or several round lumps of different sizes can be felt under the eyelid skin, ranging from rice grains and mung beans to soybeans and cherries. Smooth surface, non-sticky skin, clear edge and no tenderness.

3. Turn your eyelids. When the mass is on the conjunctival surface, purple or gray-red localized protuberance can be seen. If there is a secondary infection, it can evolve into a sty.

4. Small lumps can be absorbed completely by themselves, or they can pierce the conjunctiva surface by themselves, and discharge the gelatinous contents to form mushroom-like granulation hyperplasia. This granulation tissue can also form papillary hyperplasia on the surface of meibomian gland through the discharge pipeline.
