Meige disease

What it is, symptoms and effects

From: MedlinePlus Genetics, National Library of Medicine

Meige disease is a condition that affects the normal function of the lymphatic system. The lymphatic system consists of a network of vessels that transport lymphatic fluid and immune cells throughout the body. Meige disease is characterized by the abnormal transport of lymphatic fluid. When this fluid builds up abnormally, it causes swelling (lymphedema) in the lower limbs.

Meige disease is classified as a primary lymphedema, which means it is a form of lymphedema that is not caused by other health conditions. In Meige disease, the lymphatic system abnormalities are present from birth (congenital), although the swelling is not usually apparent until puberty. The swelling often begins in the feet and ankles and progresses up the legs to the knees. Some affected individuals develop non-contagious skin infections called cellulitis or erysipelas in the legs, which can further damage the vessels that carry lymphatic fluid.

Causes and biological mechanisms

From: MedlinePlus Genetics, National Library of Medicine

The cause of Meige disease is unknown. The condition is thought to be genetic because it tends to run in families, and other forms of primary lymphedema have been found to have a genetic cause. Researchers have studied many genes associated with the lymphatic system; however, no genetic change has been definitively found to cause the signs and symptoms of Meige disease.

Inheritance and family implications

From: MedlinePlus Genetics, National Library of Medicine

Meige disease appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of an altered gene in each cell is sufficient to cause the disorder, although no genes have been associated with Meige disease.

People with Meige disease usually have at least one other affected family member. In most cases, an affected person has one parent with the condition. When the condition occurs in only one person in a family, the condition is described as Meige-like disease.

How common is it?

From: MedlinePlus Genetics, National Library of Medicine

The prevalence of Meige disease is unknown. Collectively, the many types of primary lymphedema affect an estimated 1 in 100,000 people younger than 20; Meige disease is the most common type of primary lymphedema.

For unknown reasons, this condition affects females about three times as often as males.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Lymphedema · Very frequent (99-80%)

Localized fluid retention and tissue swelling caused by a compromised lymphatic system.

Absence of lymph node germinal center · Frequent (79-30%)

Absence of germinal centers in lymph nodes. Germinal centers are the parts of lymph nodes in which B lymphocytes proliferate, differentiate, mutate through somatic hypermutation and class switch during antibody responses.

Atypical scarring of skin · Frequent (79-30%)

Atypically scarred skin .

Cellulitis · Frequent (79-30%)

A bacterial infection and inflammation of the skin und subcutaneous tissues.

Cobblestone-like hyperkeratosis · Frequent (79-30%)

The presence of verrucous, cobblestone-like papules and nodules in a region of skin that is said to have an appearance like that of cobblestones.

Lymph node hypoplasia · Frequent (79-30%)

Underdevelopment of the lymph nodes.

Pedal edema · Frequent (79-30%)

An abnormal accumulation of excess fluid in the lower extremity resulting in swelling of the feet and extending upward to the lower leg.

Predominantly lower limb lymphedema · Frequent (79-30%)

Localized fluid retention and tissue swelling caused by a compromised lymphatic system, affecting mainly the legs.

Recurrent bacterial skin infections · Frequent (79-30%)

Increased susceptibility to bacterial infections of the skin, as manifested by recurrent episodes of infectious dermatitis.

Recurrent skin infections · Frequent (79-30%)

Infections of the skin that happen multiple times.

Skin dimple · Frequent (79-30%)

Skin dimples are cutaneous indentations that are the result of tethering of the skin to underlying structures (bone) causing an indentation.

Skin erosion · Frequent (79-30%)

A discontinuity of the skin exhibiting incomplete loss of the epidermis, a lesion that is moist, circumscribed, and usually depressed.

Edema of the dorsum of hands · Occasional (29-5%)

An abnormal accumulation of fluid beneath the skin on the back of the hands.

Laryngeal edema · Occasional (29-5%)

An abnormal accumulation of fluid and swelling in the tissues of the larynx.

Other findings in the same source

From: Orphanet

Additional reported features include Periorbital edema (Occasional (29-5%)); Peripheral edema (Occasional (29-5%)); Pleural effusion (Occasional (29-5%)); Skin ulcer (Occasional (29-5%)); Varicose veins (Occasional (29-5%)); Angiosarcoma (Occasional (29-5%)); Facial edema (Occasional (29-5%)). This is a selected summary, not a complete description of the condition.

Which doctor should you see?

The suggested department for discussing Meige disease is Clinical Genetics, with a clinical geneticist as the relevant type of clinician. Paediatrician (children) or physician (adults), with clinical geneticist referral.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Does the exact genetic or chromosome finding explain the observed features?
• Would a genetic counsellor help the family understand the result?
• Which organ-specific assessments are appropriate for this particular diagnosis?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Meige disease. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
