Sometimes we get really scared when we see small changes in our children's bodies, don't we? Especially if we don't know exactly what those things are. Today we are going to talk about a rare but very important condition to be aware of. This is called Complex Lymphatic Anomalies , or (CLA) for short. Some people also called it (Lymphangiomatosis) before. So you may hear both of these names.
First, let's see, what are Complex Lymphatic Anomalies (CLA)?
Simply put, Complex Lymphatic Anomalies (CLA) are a rare but potentially congenital condition in which a child develops benign tumors called lymphatic malformations or lymphangiomas in the child's lymphatic system. These tumors can grow into the child's bones, connective tissue, and other organs, causing damage.
Just think, even if our child has this condition when they are born, most of the time the symptoms start to appear when they are a little older, maybe a few years later. That's why it's sometimes too late to recognize this.
So, what is this Lymphatic System?
Okay, now you're probably wondering what the lymphatic system is. Simply put, it's an amazing defense system in our body. It's like the soldiers in our country. This lymphatic system helps our body to prevent diseases and fight them if they do. It's an important part of our immune system.
The lymphatic system is made up of a network of small tubes called lymphatic vessels, glands like lymph nodes, and organs like the spleen. These lymphatic vessels are like small tubes. They collect lymph fluid from the tissues of the body, filter it, clean it, and then return it to the blood. Isn't this an amazing job?
There are two types of CLA: Isolated and Systemic.
Complex Lymphatic Anomalies can be divided into two main types:
1. Isolated CLAs: This is when the tumors are confined to one area of the child's body. For example, they may only affect the chest cavity. In this case, the lungs and the soft tissues of the chest (mediastinum) are most affected.
2. Systemic CLAs: In this case, these tumors can occur in multiple places on the child's body, such as the bones, chest, and abdomen.
In this way, symptoms and treatments may vary depending on the area affected.
What are the main types of Complex Lymphatic Anomalies (CLA)?
There are four main types of CLA. Although each type has some of the same symptoms, they are distinct conditions. And the gene mutations that cause them are also different.
- Generalized Lymphatic Anomaly (GLA): This condition usually affects different parts of the child's body. For example, these tumors can occur in the bones, spleen, liver, lungs, and soft tissues of the chest (mediastinum).
- Kaposiform Lymphangiomatosis (KLA): This is the most severe and rapidly spreading type of CLA. In KLA, the lymphatic vessels that carry lymph fluid throughout the child's body become enlarged. This causes them to invade and damage the organs, bones, and tissues around them.
- Central Conduction Lymphatic Anomaly (CCLA): Children with CCLA also have enlarged lymph vessels. However, in CCLA, these enlarged vessels are mostly located in the torso. This can affect the digestive system and prevent the child from properly draining lymph fluid from the body.
- Gorham-Stout Disease (GSD): Also known as Gorham's disease, this condition causes large amounts of bone to dissolve due to the formation of lymphatic vessels within the bones. It is also called "vanishing bone disease." It can affect any bone. However, children with GSD most often experience bone loss in the ribs, skull, collarbone, and cervical spine.
How common is this CLA condition?
Complex Lymphatic Anomalies are actually a very rare condition. Because they are not so common, it can sometimes be difficult for doctors to accurately diagnose them. Therefore, if you have symptoms, it is very important to see a specialist as soon as possible.
What causes this CLA?
Doctors and researchers are still trying to figure out what causes CLA. However, recent research suggests that the condition can be caused by both hereditary gene mutations that are passed down from parents to children, as well as somatic gene mutations that occur after birth. This means that it is genetically linked.
Who is at risk of developing CLA?
Complex Lymphatic Anomalies can affect anyone. Specifically, the symptoms of this condition usually appear in late childhood or adolescence. So, even if the condition is present at birth, it may take some time for symptoms to show.
So, what are the symptoms of CLA?
Symptoms can vary from child to child with this disease. Also, symptoms vary depending on which organ system is affected and how severe it is. Most of the time, this disease progresses slowly. Therefore, we may not pay much attention to some of the symptoms, or we may think that they are due to another disease.
If your child's respiratory system is affected:
At this time, asthma-like symptoms may appear.
- Persistent cough.
- Difficulty breathing (dyspnea).
- Wheezing ( a whistling sound ) when breathing.
If your child's skeletal system is affected:
- Pain in bones or joints.
- Even a small fall can cause fractures .
- Numbness in the limbs.
- Pain or weakness caused by nerve compression .
If your child's digestive system is affected:
- Abdominal distension and abdominal pain .
- Anemia and constant fatigue.
- Diarrhea.
- The food is tasteless.
- Nausea and vomiting.
- Weight loss for no reason.
If your child's urinary system is affected:
- Blood in the urine (hematuria).
- Flank pain .
- High blood pressure in children.
If your child has one or more of these symptoms, please seek medical advice. These are not symptoms that are specific to CLA, but it is important to get tested.
How do doctors diagnose this CLA condition?
Because CLA is a rare condition and the symptoms vary, it can sometimes be difficult for doctors to diagnose the exact condition. Since it often affects children's lungs and bones, your child's doctor may order tests such as:
- Bronchoscopy: To check for infection or other abnormalities in the airways.
- Pulmonary function testing: Measure how well your lungs are working.
- Whole-body MRI: To check for things like affected organs, bone lesions, or fluid in the abdomen.
- X-rays: To further examine bones that appear suspicious or injured on the MRI. Chest X-rays can also look for abnormalities in the lungs.
Sometimes doctors take a small sample of lymph nodes and tissue (biopsy) and examine it under a microscope. While this test can definitively diagnose CLA, it can sometimes cause complications, such as a collection of lymph fluid around the lungs (chylothorax). Because of this, doctors often rely on less invasive tests to make a diagnosis.
How is CLA treated?
Because CLA can affect multiple areas of a child's body, doctors work together, that is, they use a multidisciplinary approach to plan treatment that is appropriate for the child. When treating CLA, the main focus is on controlling the child's symptoms. To do this, you can do things like:
- Bone grafting: For bone damage in conditions like GSD.
- A high-protein diet or intravenous nutrition (total parenteral nutrition or TPN).
- Sclerotherapy: To shrink or deactivate tumors or lymph vessels.
- Surgery: To remove tumors or to insert small tubes (shunts) to facilitate the flow of lymph fluid.
- Radiation therapy or chemotherapy: To shrink noncancerous tumors (these are only used in very severe, life-threatening cases).
Recently, targeted therapies that target the genetic mutations that cause this condition have also been used. These therapies have also been shown to be effective as first-line treatments for CLA.
Can Complex Lymphatic Anomalies (CLA) be prevented?
Unfortunately, no . CLA occurs during pregnancy, and the exact cause is unknown. So, there was nothing you could do to prevent your baby from developing this condition.
What are the possible complications of CLA?
CLA can put your child at risk for:
- Ascites: Fluid accumulation in the abdomen.
- Bone fractures.
- Chylothorax and Chylopericardium: A collection of a milky fluid (chyle) containing lymph fluid and fat in the membrane covering the lungs (pleura) or the sac around the heart (pericardium).
- Collapsed lung / pneumothorax.
- Liver failure.
- Paralysis.
- Pericardial effusion.
- Pleural effusion and cardiogenic pulmonary edema.
Some of these complications can be very serious, so it is important to be aware of the symptoms and follow your doctor's instructions.
What is the future of someone with CLA?
There is no cure for Complex Lymphatic Anomalies (CLA). Your child's future depends on which body systems are affected and how severe the symptoms are.
Pleural effusions are the leading cause of death among people with CLA. However, with proper treatment and management, a child can be helped to live a normal life.
When should I see a doctor?
If your child has any of these symptoms, see a doctor immediately:
- Pain in the stomach or intestines.
- If there is blood in the urine.
- Persistent cough, wheezing, or difficulty breathing.
- Unexplained nausea, fatigue, or weight loss.
If you have any of these, please see a doctor without delay.
What should I ask the doctor?
You may want to ask your child's doctor questions like these:
- What parts of my child's body has this condition affected?
- What treatment options are available for my child?
- Does my child need surgery?
- Should I be aware of symptoms of complications?
It is very important to ask these questions and gain a clear understanding of the situation.
Finally, I have to say...
When you find out that your child has CLA (lymphangiomatosis), it's normal to feel scared and worried about how it will affect their health and future. Many of us may have never heard of this disease before. And there's nothing you could have done to prevent it.
The first step to helping your child is to be well-informed about this disease, its symptoms, and treatments. See a doctor who specializes in lymphatic system diseases. They can answer your questions and provide the specific medical care your child needs.
Although there is no cure for CLA, proper treatment and management can help your child live a happy and healthy life. So, stay strong and do the best you can for your child.
