A fairly large number of people experience swelling of the legs. When swelling of the foot or lower leg with tense veins is observed in the evening, and the swelling disappears in the morning, this is not good: these are distant harbingers of varicose veins or thrombophlebitis... But if the swelling becomes more noticeable every day and does not go away in the morning, then a no less alarming diagnosis is likely - lymphostasis of the lower extremities.
Lymphostasis of the arm is a serious disease that causes persistent swelling. Let's look at the causes of the disease, treatment methods and preventive measures that will help get rid of lymphostasis.
Lymphostasis is a disorder of lymph outflow, accompanied by edema. The volume of the limb increases in this condition. Severe lymphostasis is called elephantiasis. The impetus for the development of lymphostasis can be an injury (bruise, injury, fracture, burn), often the disorder of lymph outflow occurs after operations.
The diagnostic evaluation of benign and malignant lymphoproliferative skin diseases is a very difficult task for the pathologist. In recent decades, significant progress has been made in this area due to advances in immunology.
Consequences of lymphopenia include the development of opportunistic infections and an increased risk of cancer and autoimmune diseases. If lymphopenia is detected during a complete blood count, diagnostic tests for immunodeficiency conditions and lymphocyte subpopulation analysis are necessary. Treatment is aimed at the underlying disease.
The causes and pathogenesis of lymphomatoid papulosis remain unknown. Many scientists consider lymphomatoid papulosis as a nodular form of skin lymphoma with slow tumor progression. The disease is observed in young and middle-aged people, more often in men.
Lymphomas of the accessory apparatus of the eye (conjunctiva, lacrimal gland and orbit) account for approximately 8% of all extranodal lymphomas. Lymphoma, like benign lymphoid hyperplasia, is classified as a lymphoproliferative disease.
Lymphomas are a heterogeneous group of neoplastic diseases originating from the reticuloendothelial and lymphatic systems. The main types of lymphomas are Hodgkin's lymphoma and non-Hodgkin's lymphomas.
Conjunctival lymphoma usually presents in old age with eye irritation or painless swelling. Slowly growing, mobile, pinkish-yellow or flesh-colored infiltrates located in the lower fornix or epibulbarly.
Lymphoid interstitial pneumonia (lymphocytic interstitial pneumonitis) is characterized by lymphocytic infiltration of the interstitium of the alveoli and air spaces.
The first description of the disease lymphocytic papulosis belongs to A. Dupont (1965). In 1968 WL Macauly introduced the term "lymphomatoid papulosis" for long-term, benign, self-healing papular rashes that have a malignant histological appearance.
Lymphocytic choriomeningitis (Acute serous meningitis of Armstrong) is a zoonotic viral infectious disease characterized by predominant damage to the meninges and choroid plexuses of the central nervous system.
Lymphocytic choriomeningitis is an acute viral disease transmitted to humans from mouse-like rodents, with serous inflammation of the meninges and brain tissue with a benign course.
Lymphedema is swelling of a limb due to hypoplasia of the lymphatic vessels (primary lymphedema) or their obstruction or destruction (secondary). Symptoms include brown skin and firm (no dent when pressed with a finger) swelling of one or more limbs.
Lymphatic drainage disorders develop when the lymph nodes are affected (inflammation, cicatricial shrinkage, metastases, tumors), vessels (inflammation, compression, trauma, malformations), ducts (usually trauma in the form of a rupture) or as a result of functional disorders in diseases of other organs and systems (allergy, phlebohypertension, renal, hepatic and cardiac failure, etc.). Lymphatic drainage disorders can be acute (temporary) and chronic.
Lymphangioma of the skin is a benign tumor of the lymphatic vessels. Lymphangioma exists from birth or develops in childhood.
Lymphangiomas are not considered tumors, but are developmental defects, representing non-functioning benign vascular malformations that extend throughout the orbit and sometimes the oropharynx.
Lymphangioleiomyomatosis (leiomyomatosis), disseminated - a pathological process characterized by tumor-like proliferation of smooth muscle fibers along the small bronchi, bronchioles, walls of blood and lymphatic vessels of the lungs, followed by microcystic transformation of the lung tissue. The disease affects only women aged 18-50 years.
Lymphangiectasia may be local, affecting the submucosa and serous membrane, combined with the expansion of lymphatic capillaries of other organs. Due to insufficient supply of amino acids, there is a violation of the synthesis of albumin, and then gamma globulins in the liver. Due to the loss of lymphocytes, lymphopenia develops.
Lymphadenitis in children is a disease that manifests itself in inflammation of the lymph nodes. Lymph nodes are part of the immune system, they are among the first to react to inflammatory processes in the body, increasing in size.
