Chalazion

Introduction Chalazion is a chronic inflammatory granuloma of the meibomian glands (lipogranuloma). It is formed on the basis of obstruction and lipid secretion retention on the duct of the meibomian gland discharge tube. The sputum granuloma is also called the meibomian gland cyst, and the Chinese medicine is called the cytoplasmic nucleus. It is a chronic inflammatory mass formed by obstruction of the drainage duct of the meibomian gland and retention of glandular secretions in the tarsal plate. The disease is more common in children and adolescents, without major pain, does not affect vision, has a tendency to self-heal, and has a good prognosis.

Cause

Chronic conjunctivitis, sebaceous glands and sweat gland secretions are strong or chronic inflammation caused by blepharitis.

It is a granulomatous inflammation containing giant cells. It is the proliferation of glandular epithelial cells. The surrounding lymphocytes, giant cells and a large number of fibrous tissues form a capsule wall due to compression, and the central tissue gradually degenerates to form a gel-like substance. Even liquefaction.

1. No symptoms, nodular swelling under the skin, no tenderness, no adhesion to the skin, flipping the eyelids, and facing the conjunctiva of the cyst, it is purple-red or gray-white (the cyst can be worn from the conjunctival surface to expose the granulation tissue).

2. There is a white pustule structure on the inside of the eye face. The eyelids are swollen. Although it is uncomfortable, it does not affect the eyesight and is easy to cause eye fatigue.

3. Repeated authors should be pathologically examined and differentiated from meibomian adenocarcinoma.

Differential diagnosis

Blepharitis, cellulitis, pyogenic granuloma, orbital tumors (if recurrent meibomian cysts should be specifically noted to exclude sebaceous gland cancer)
