It is the inflammation of the lymphatic system, which is an important part of the immune system .
The lymphatic system consists of a network of organs, cells, ducts and glands or “nodules” that can be found throughout the body, but are more evident under the jaw, in the armpits and in the groin.
The local inflammation of the lymphatic vessels can be acute or chronic.
The organs that make up the lymphatic system include:
- Bone marrow.
- Base .
- Thymus (a small organ located in the upper part of the thorax that helps develop white blood cells).
Immune cells called lymphocytes mature inside the bone marrow and then travel to the lymph nodes and other organs within the lymphatic system to help protect the body against viruses and bacteria.
The lymphatic system also filters a whitish fluid called lymph, which contains white blood cells that kill bacteria.
The lymph travels through the body along the lymphatic vessels, or channels, and collects fats, bacteria and other waste products from cells and tissues.
The lymph nodes then filter out these harmful materials from the lymph and produce more white blood cells to fight infections.
Lymphangitis occurs when viruses and bacteria infect the lymphatic system channels, usually through a cut or wound that has become infected.
Often there will be red and soft streaks that go from the wound to the nearest lymphatic glands.
Other symptoms include fever, chills and a general feeling of discomfort.
If treated quickly, lymphangitis often goes away without harmful effects.
If left untreated, complications can occur and the condition can be very serious.
Lymphangitis is sometimes mistakenly called ” blood poisoning “, and sometimes it is mistaken for thrombophlebitis , the presence of a clot in a vein.
Causes of lymphangitis
Lymphangitis occurs when bacteria or viruses enter the lymphatic channels.
They can enter through a cut or wound, or they can grow from an existing infection.
This inflation usually occurs by an acute and sudden infection of streptococci or staphylococci.
Both infections are caused by bacteria.
Lymphangitis can occur if a pre-existing infection of the skin worsens.
This could mean that the bacteria will soon enter the bloodstream.
This can cause complications such as sepsis , a potentially fatal condition of inflammation throughout the body.
Another cause of lymphangitis is the compression of the lymphatic vessels by the presence of a tumor.
- When the patient suffers from diabetes mellitus.
- The chronic use of steroids.
- A prolonged time with a peripheral venous catheter.
- Infection caused by varicella.
- Immunocompromised patients.
- Bites of humans, animals or insects.
- Fungal type skin infections.
- The presence of any skin trauma.
- Chronic use of steroids
Children with systemic diseases are more likely to develop severe lymphangitis.
Gardeners and farmers can develop the condition if they contract sporotrichosis, a fungal infection transmitted by pathogens present in the soil.
- The presence of macular linear red stripes often trace the surface of the skin from the infected area to the nearest lymphatic gland.
- They may be weak or very visible and sensitive to touch.
- They can extend from a wound or cut. In some cases, the streaks may form blisters.
Other symptoms include:
- The presence of colds.
- The lymphatic glands become inflamed.
- Presence of fever and chills.
- Sensation of general discomforts.
- The loss of appetite
- The headaches.
- Muscular pains
- Sensitivity and heat on the affected skin.
- Loss of appetite
The symptoms are severe if the patient presents:
- High fever.
- Systemic toxicity.
- Altered mental state
Diagnosis of lymphangitis
The doctor will perform a physical examination, where the lymph nodes will be palpated to verify the swelling, the presence of abscesses or skin trauma, cutting, abrasion or fungal infection will be verified.
The doctor can also order various diagnostic and interpretation tests such as:
- A biopsy to reveal the cause of the swelling.
- A blood culture, to verify if the infection has been transferred to the blood.
- A complete blood count can show the presence of leukocytosis.
- Aspiration and culture of any exudate or pus, to guide any treatment with antibiotics.
Within the commonly associated conditions are:
- Lymphedema .
- Lymph node dissection.
- Athlete’s foot.
- Cellulitis .
- Erysipelas that often coexists with this inflammation.
- Lymphatic filariasis or elephantiasis.
- Septic thrombophlebitis .
- Superficial thrombophlebitis, in this case induration is felt on the vein.
- Contact dermatitis.
- Allergic reactions.
There are two types of lymphangitis:
- Reticular: edema in the form of a grid filled with white blood cells, a kind of red cord is observed, hardened and painful, causing hyperthermia in the affected area. There are no signs like fever.
- Troncular: this type of lymphangitis is reticular but associated with signs such as fever (40 ° C) with malaise. Complications such as abscesses, bursitis and lymphedema may arise .
- Deep: this is the weirdest way. Signs such as fever and the peculiarity that the pain is exacerbated when the palpation is performed.
It is produced by external agents such as parasites or viruses.
The lymphatic walls swell, occupying the entire orifice of the vessel.
The symptoms will vary depending on the causative agent of lymphangitis.
Among these are those caused by parasites and other agents that cause underlying diseases.
The treatment of acute lymphangitis consists of rest, immobilization of the affected limb, and medications such as anti-inflammatory and anti-edema, in addition heparin is recommended to prevent possible complications.
Often surgery is not needed except for certain complications.
When it comes to this type of lymphangitis, the treatment is directed to the pathogen that causes it, and is accompanied by a rehabilitation therapy.
Also in this case the surgical treatment is directed to secondary manifestations.
The treatment must begin immediately to prevent the disease from spreading and consists of:
- Oral antibiotics, to treat infection such as Dicloxacillin , Nafcillin, Cephalexin and Clindamycin if you are allergic to penicillin or cephalosporin .
- Pain medications, such as acetaminophen or ibuprofen.
- Anti-inflammatory drugs, to reduce swelling.
- Surgery, to drain any abscess that may have formed.
- Intravenous antimicrobial therapy, such as trimethoprim-sulfamethoxazole.
It can help to heal and relieve pain by applying warm compresses.
Pour hot water over a cloth or towel and apply it to the sensitive area and apply three times a day.
The heat will promote blood flow and stimulate healing.
You can also take a warm shower and placing the shower head over the infected area.
If possible, keep the infected area elevated.
This helps reduce swelling and slows down the spread of the infection.
Complications of lymphangitis
Lymphangitis can spread rapidly, leading to complications such as:
- Cellulitis (a skin infection)
- Bacteremia (bacteria in the blood).
- Sepsis (body inflammation)
- Abscesses (painful accumulation of pus, usually with swelling and inflammation).
If bacteria enter the bloodstream, the condition can lead to death.
