Chalazion
Introduction
Introduction to sputum Chalazion is a chronic inflammatory granuloma (lipogranuloma) of the meibomian glands that is formed on the obstruction of the meibomian gland discharge tube and the retention of lipid secretions. Chronic conjunctivitis is a granulomatous inflammation containing giant cells. Initially, the glandular epithelial cells proliferate. 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. Forming a gel-like substance, even liquefaction. It can be associated with chronic conjunctivitis caused by bacterial infection. It is a chronic inflammation of the conjunctiva caused by various causes, including bacterial infection, stimulation of adverse environment, influence of eye disease, and poor living habits. Its clinical features are ocular discomfort, white foamy secretions, mild congestion of the palpebral conjunctiva or incongestion. Itching, foreign body sensation, aggravation at night or reading; sputum conjunctival hyperemia, white foamy secretions in the palate. basic knowledge The proportion of illness: 15% Susceptible people: no specific population Mode of infection: non-infectious Complications: conjunctivitis
Cause
Cause of sputum granuloma
Cause:
Chronic inflammatory granuloma of the meibomian glands is eventually caused by obstruction of the drainage of the meibomian glands and retention of secretions. Chronic inflammatory stimuli caused by sebaceous glands and sweat gland secretions or 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.
Prevention
Chalcopy prevention
The sacral sac is caused by the obstruction of the meibomian gland (McG), and the secretion of the gland cannot be discharged. In general, the occurrence of sputum is closely related to the individual's physique. If the skin is particularly greasy, it is more likely to occur. The methods are:
1. Keep the eyes clean.
2. Do not let your eyes get too tired.
Complication
Chalillary complication Complications conjunctivitis
It can be associated with chronic conjunctivitis caused by bacterial infection. It is a chronic inflammation of the conjunctiva caused by various causes, including bacterial infection, stimulation of adverse environment, influence of eye disease, and poor living habits. Its clinical features are ocular discomfort, white foamy secretions, mild congestion of the palpebral conjunctiva or incongestion. Itching, foreign body sensation, aggravation at night or reading; sputum conjunctival hyperemia, white foamy secretions in the palate.
Symptom
Symptoms of sputum granuloma Common symptoms Cyst swelling sputum secondary infection Eyelid foreign body eyelid edema skin adhesion
1, the course of the disease is slow, generally no obvious symptoms, no pain sometimes only a heavy feeling, may cause temporary astigmatism due to lumps of oppression, or the tumor oppresses the eyeball and cause foreign body sensation.
2, under the eyelids can touch one to several round lumps of varying sizes, ranging from rice grains, mung beans, to soy beans, cherries, smooth surface, no adhesion to the skin, clear edges, no tenderness.
3, flip the eyelids in the tumor on the conjunctival surface, visible purple red or gray red local bulge, if there is secondary infection, can evolve into sty, it is difficult to distinguish between the formation and internal sty.
4. The small mass can be completely absorbed by itself, or the conjunctival surface can be worn by itself, and the contents of the gelatinous sample can be discharged to form a budding-like granulation-like proliferation. The granulation tissue can also form a nipple on the surface of the gingival margin through the discharge duct of the meibomian gland. Proliferation.
5. When there is a secondary sensation, the internal styrene can be formed.
6, elderly patients, especially after repeated attacks, should be sent to the pathological examination of the resected specimens to rule out the possibility of meibomian adenocarcinoma.
Examine
Examination of hernia
Under the eyelids, one to several round lumps of varying sizes can be touched, ranging from rice grains to mung beans to large soybeans and cherries. There is no redness and tenderness on the surface of the skin. Turn over the eyelids in the lumps on the conjunctival surface, showing a purple-red or gray-red limited bulge. Elderly patients, especially those who have been repeatedly reported after surgery, should be sent to the pathological examination to exclude the possibility of meibomian adenocarcinoma.
Diagnosis
Diagnosis and differentiation of sputum
diagnosis
1, no symptoms, no subcutaneous nodules, no tenderness, no adhesion to the skin, flip the eyelids, the conjunctiva at the cyst is purple or grayish white (the cyst can be worn through the conjunctival surface, revealing granulation tissue).
2, repeated authors, should be pathological examination, and identification of meibomian adenocarcinoma.
Blepharitis, cellulitis, pyogenic granuloma, orbital tumors (if recurrent meibomian cysts should be specifically noted to exclude sebaceous gland cancer).
