Meibomian gland cyst
Introduction
Introduction to meibomian gland cyst The meibomian gland cyst is an idiopathic aseptic chronic granulomatous inflammation of the meibomian gland, formerly known as hernia. Chronic granulomatous gland enlargement caused by obstruction of the glandular ducts of the meibomian glands and surrounding tissues. When the meibomian gland cyst is onset, there is eyelid edema, swelling and irritation, and mumps may not be easily distinguished. After a few days, the above symptoms subsided, leaving only a painless, slow-growing round mass on the surface. The skin can be loosened, and the mass can appear on the eyelid plate. It is usually expressed as a red or gray mass under the conjunctiva. When the mass occurs in the lower iliac crest, chronic dacryocystitis should be excluded. basic knowledge The proportion of illness: 1% Susceptible people: no special people Mode of infection: non-infectious Complications: eyelid hematoma
Cause
Causes of meibomian gland cyst
Chronic granuloma of the epiphysis formed by the obstruction of the meibomian gland discharge tube, secretion retention, and stimulation of surrounding tissues. More common in adolescents or middle-aged. It may be related to the strong secretion of meibomian glands at this age. Most of them happen to the Shangyu.
Prevention
Mesenteric cyst 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
Mesenteric cyst cyst complications Complications, orbital hematoma
Most of the complications occurred after surgical treatment, such as induration of subcutaneous hematoma, scarring of eyelid skin and so on.
Symptom
Common symptoms of meibomian gland cysts Common symptoms of ptosis cysts
The disease progresses slowly, with no self-conscious symptoms. It can get a hard knot under the eyelid skin, the surface is smooth, the skin is non-adhesive, no tenderness, the big one can see the skin bulge, but there is no redness and swelling, the patient feels heavy eyelids, and there may be a light vacation. The sag is drooping. Turn over the eyelids, see the area of the lesion where the conjunctival surface is purple or grayish red, sometimes from the conjunctival surface to break through, discharge the glue-like contents, the mass subsides. However, there may be granulation tissue proliferation, which produces a sense of friction. The granulation tissue appears at the discharge port of the meibomian gland, and the sacral margin has papillary proliferation, which is called the meibomian gland cyst of the iliac crest.
Examine
Examination of meibomian gland cyst
The rounded mass of the eyelids is different in size, does not hurt, and does not adhere to the skin. Patients often see a foreign body. The diagnosis of this disease is easy, but for elderly patients or patients with recurrent induration, it is necessary to consider whether there is meibomian adenocarcinoma, and the specimen should be sent to the pathology examination after surgery.
Diagnosis
Diagnosis and differentiation of meibomian gland cyst
According to the patient without obvious pain, eyelid induration, can be diagnosed. For recurrent or elderly meibomian gland cysts, the resection should be pathologically examined to exclude meibomian adenocarcinoma.
Should be differentiated from meibomian adenocarcinoma, stye and so on.
