This disease is caused by problems in the circulatory system, so when it is presented, in the beginning it is important to follow several recommendations. The person needs to keep the legs elevated as much as possible to help the return of the blood. Whenever sitting down, the person needs to keep the legs on a foot stool. At night it is advisable to sleep with a pillow under the lower legs. In the evening, t is not unusual for legs to be swollen. The volume of the lower leg can increase to up to 100ml after a long working day or up to 200ml after a long-haul flight without moving.

In the example of the 41-year-old Japanese man the lesions were much improved by washing and topical use of corticosteroids for two months, also oral antibiotics like cephalexin are used if cellulitis is present. Moist exudative inflammation and moist ulcers respond to tepid wet compresses of Burow’s solution or just saline or water for 30 to 60 minutes several times a day. But in worse cases, edema that does not disappear spontaneously within a few hours or after a walk, is described as pathological, so it needs to have a special treatment. It is very important to say that Papillamitosis, bilateral and marked edema with few symptoms is mostly caused by the systemic circulation (heart, kidneys, liver).

Papillamitosis is associated, as has been mentioned before, with symptoms and/or clinical signs such as dilated superficial veins, varicose veins and changes in the skin. Edema and its complication Papillamitosis are only partially reversible and soon becomes hard, which is mainly confirmed on palpation. All skin structures are affected and this is characterized by the term. Lymphoedema may develop in many cases accompanied by acral thickening of the skin folds, hyperkeratosis and papillomatosis.

According the Fifth WHO Expert Committee on Filariasis , the most common method of classification of lymphedema is as follows: (The same classification method can be used for both primary and secondary lymphedema)

The International Society of Lymphology (ISL) Staging System is based solely on subjective symptoms, making it prone to substantial observer bias. Imaging modalities have been suggested as useful adjuncts to the ISL staging to clarify the diagnosis. The lymphedema expert Dr. Ming-Huei Cheng developed a Cheng’s Lymphedema Grading tool to assess the severity of extremity lymphedema based on objective limb measurements and providing appropriate options for management.

The diagnosis is based on the combination of the symptoms. Generally, people are diagnosed with yellow nail syndrome if they have two or three of the three classical symptoms (yellow nails, lymphedema and lung problems). The nail changes are considered essential for the diagnosis, but they can be subtle.

Pulmonary function testing can show obstruction of the airways. People with pleural effusions may show evidence of restriction in lung volumes due to the fluid. Analysis of the fluid in pleural effusions generally shows high levels of protein but low levels of cholesterol and lactate dehydrogenase, but about 30% of effusions are chylous (chylothorax) in that they have the characteristics of lymph.

A lymphogram may be performed in people with lymphedema. This can show both under developed (hypoplastic) lymphatic ducts and dilated ducts. Dye may be found in the skin months after the initial test. Scintigraphy of lymph flow (lymphoscintigraphy) shows delays in drainage of lymph (sometimes asymmetrically), although this test can also be normal.

Accurate diagnosis and staging are fundamental to the management of lymphedema patients. A swollen limb can result from different conditions that require different treatments. Diagnosis of lymphedema is currently based on history, physical exam, limb measurements, and imaging studies such as lymphoscintigraphy and indocyanine green lymphography. However, the ideal method for lymphedema staging to guide the most appropriate treatment is controversial because of several different proposed protocols.

Lymphedema can occur in both the upper and lower extremities, and in some cases, the head and neck. Assessment of the extremities first begins with a visual inspection. Color, presence of hair, visible veins, size and any sores or ulcerations are noted. Lack of hair may indicate an arterial circulation problem. Given swelling, the extremities' circumference is measured for reference as time continues. In early stages of lymphedema, elevating the limb may reduce or eliminate the swelling. Palpation of the wrist or ankle can determine the degree of swelling; assessment includes a check of the pulses. The axillary or inguinal nodes may be enlarged due to the swelling. Enlargement of the nodes lasting more than three weeks may indicate infection or other illnesses such as sequela from breast cancer surgery requiring further medical attention.

Diagnosis or early detection of lymphedema is difficult. The first signs may be subjective observations such as "my arm feels heavy" or "I have difficulty these days getting rings on and off my fingers". These may be symptomatic of early stage of lymphedema where accumulation of lymph is mild and not detectable by changes in volume or circumference. As lymphedema develops further, definitive diagnosis is commonly based upon an objective measurement of differences between the affected or at-risk limb at the opposite unaffected limb, e.g. in volume or circumference. No generally accepted criterion is definitively diagnostic, although a volume difference of 200 ml between limbs or a 4-cm difference (at a single measurement site or set intervals along the limb) is often used. Bioimpedance measurement (which measures the amount of fluid in a limb) offers greater sensitivity than existing methods.

Chronic venous stasis changes can mimic early lymphedema, but the changes in venous stasis are more often bilateral and symmetric. Lipedema can also mimic lymphedema, however lipedema characteristically spares the feet beginning abruptly at the medial malleoli (ankle level). Lipedema is common in overweight women. As a part of the initial work-up before diagnosing lymphedema, it may be necessary to exclude other potential causes of lower extremity swelling such as renal failure, hypoalbuminemia, congestive heart-failure, protein-losing nephropathy, pulmonary hypertension, obesity, pregnancy and drug-induced edema.

There is no cure for CPL; the aim of treatment is to relieve the signs of the disease, and to slow the progression. Management requires daily care to prevent infection of the affected skin. The first step is to trim the feather from the lower leg, to ensure no affected areas are missed, and to allow application of treatments directly to the affected skin. Bacterial infections can be treated by gentle washing and drying of the skin. Topical treatments are required to treat chorioptic mange (caused by the mite "Chorioptes equi"), as the mites are not vulnerable to oral or systemic treatments when they are within the crusts on the skin. Daily exercise assists with the flow of lymph. Combined decongestive therapy involves massage of the leg to move the lymph, followed by specialized compression bandaging which creates a pressure gradient up the leg.

Horses with CPL often have poor-quality hoof, so regular trimming is required to help keep the hoof healthy.

The cornerstone of prevention and treatment of podoconiosis is avoidance of exposure to irritant soils. Wearing shoes in the presence of irritant soils is the primary method of exposure reduction. In Rwanda, a country of high disease prevalence, the government has banned walking barefoot in public, in order to curtail podoconiosis and other soil-borne diseases.

Once the disease has developed, rigorous foot hygiene including daily washing with soap and water, application of an emollient, and nightly elevation of the affected extremity has been shown to reduce swelling and disability. Compression wrapping and decongestive physiotherapy of the affected extremity has been shown to be effective in other forms of lymphedema, but the benefits of these therapies have not been rigorously studied in podoconiosis. Nodules will not resolve with these conservative measures, although surgical removal of the nodules can be performed.

People with yellow nail syndrome have been found to have a moderately reduced lifespan compared to people without the condition.

The differential diagnosis for podoconiosis includes other causes of tropical lymphedema, such as filariasis or leprosy, and mycetoma pedis. Podoconiosis begins almost exclusively in the foot, as opposed to filariasis, where the initial edema can appear anywhere in the lower extremities. Podoconiosis is usually asymmetrically bilateral, whereas filariasis and mycetoma are usually unilateral. Additionally, groin involvement with podoconiosis is extremely rare and is usually indicative of filariasis.

If a clinical distinction between podoconiosis and filariasis cannot be made based on history and examination alone, blood smears and ELISA antigen testing can be useful to screen for filariasis.

The disfigurement associated with podoconiosis can include soft or firm edema, and in later stages firm nodules and a mossy appearance, whereas mycetoma is characterized by firm nodules and edema, usually without the mossy appearance of podoconiosis. Additionally, the edema of podoconiosis is typically more striking and extends more proximally than the edema of mycetoma. Radiology can help distinguish between podoconiosis and mycetoma if the diagnosis is questionable.

Local epidemiology can also be a clue to diagnosis, as podoconiosis is typically found in higher altitude areas with volcanic soils, whereas mycetoma is found along the "mycetoma belt" between latitudes 15 south and 30 north, and filariasis is uncommon at higher altitudes and other environments in which the mosquito vector is less prevalent.

Podoconiosis can be distinguished from leprosy by the preservation of sensation in the affected limb and the isolation of disease to the lower extremities.

Treatment consists of antibiotics, elevation of the affected limb, and compression. For persons with elephantiasis nostras who are overweight or obese, weight loss is recommended. Oral retinoids have been used to treat the cutaneous manifestations of the disease.

Stasis Papillomatosis is similar to AGEP (Acute generalized exanthematous pustulosis) from pustular psoriasis; criteria for histopathologic distinction have been proposed: papillary edema, vasculitis, exocytosis of eosinophils and single-cell necrosis of keratinocytes in AGEP and acanthosis and papillomatosis in pustular psoriasis.

An example that illustrates the difference between SP and Stasis Papillomatosis and the histology diagnosis is … “a markedly obese, 41-year-old Japanese man who had suffered from psoriasis vulgaris for several years visited hospital with elephantiasis-like swelling of his lower legs of three months' duration. His right lower leg showed marked papillomatosis with thick scales, and the left lower leg was eroded and papillomatous. Although direct lymphography of his lower extremities showed no abnormality, indirect lymphography revealed local lymphatic damage in the involved skin”. Histological examination showed hyperkeratosis, marked papillomatosis, proliferation of capillaries in the upper dermis, and lymphectasia in the lower dermis. It was suspected that obesity and the preceding psoriatic lesions caused local lymphatic disturbances, followed by the development of stasis papillomatosis.

Affected breeds include the Shire, Clydesdale, Belgian, Gypsy cob, and Friesian. Signs are usually only seen in horses older than two years. Both sexes are affected.

The most informative test is to scrape the lesion and add potassium hydroxide (KOH), then examine under a microscope. (KOH scrapings are commonly used to examine fungal infections.) The pathognomonic finding is observing medlar bodies, sclerotic cells. Scrapings from the lesion can also be cultured to identify the organism involved. Blood tests and imaging studies are not commonly used.

On histology, chromoblastomycosis manifests as pigmented yeasts resembling "copper pennies". Special stains, such as periodic acid schiff and Gömöri methenamine silver, can be used to demonstrate the fungal organisms if needed.

The course of ACA is long-standing, from a few to several years, and it leads to extensive atrophy of the skin and, in some patients, to the limitation of upper and lower limb joint mobility.The outlook is good if the acute inflammatory stage of ACA is treated adequately. The therapeutic outcome is difficult to assess in patients with the chronic atrophic phase, in which many changes are only partially reversible.

Physicians should use serologic and histologic examination to confirm the diagnosis of ACA. Treatment consists of antibiotics including doxycycline and penicillin for up to four weeks in the acute case.

No preventive measure is known aside from avoiding the traumatic inoculation of fungi. At least one study found a correlation between walking barefoot in endemic areas and occurrence of chromoblastomycosis on the foot.

Although elephantiasis nostras resembles the elephantiasis caused by helminths, it is not a filarial disease. Instead, it is a complication of chronic lymphedema. Both elephantiasis nostras and filarial elephantiasis are characterized by impaired lymphatic drainage, which results in excess fluid accumulation.

Lipedema is commonly misdiagnosed. At this time, only Germany and the Netherlands have standardized ways of diagnosing lipedema. Other countries do not currently have a standardized diagnosis protocol, and therefore the diagnosis is typically made clinically via physical inspection (palpating the adipose tissue).

Some trained clinicians and therapists can feel the physical differences in the adipose tissue, characterized as nodules with "beans in a bag" feeling. When the tissue has excess fluid the nodules are no longer easily palpable. Testing of the major components of the lymphatic system can be done through tools such as lymphoscintigraphy, but lack of noticeable lymphatic impairment does not indicate lipedema is not present, only that the major lymphatics are not (yet) affected.

Washing the infected area with an antiseptic solution is part of the treatment for mud fever. However, washing a horse's legs repeatedly can remove the natural oils in the skin and may allow the condition to become established. The legs should be dried thoroughly after washing with antibacterial shampoo using paper towels,

There is no uniform prognosis across all patients. Some patients have success managing the symptoms with conservative and/or surgical treatments. Some patients progress to lipo-lymphedema, a condition where lipedema and lipo-lymphedema both occur. Some patients develop Dercum's disease.

The horse should be kept in a clean, dry indoor barn stall with wood shavings for bedding to prevent a moist environment around the legs.

It is not practical to test or decontaminate most sites that may be contaminated with "H. capsulatum", but the following sources list environments where histoplasmosis is common, and precautions to reduce a person's risk of exposure, in the three parts of the world where the disease is prevalent. Precautions common to all geographical locations would be to avoid accumulations of bird or bat droppings.

The US National Institute for Occupational Safety and Health (NIOSH) provides information on work practices and personal protective equipment that may reduce the risk of infection. This document is available in English and Spanish.

Authors at the University of Nigeria have published a review which includes information on locations in which histoplasmosis has been found in Africa (in chicken runs, bats and the caves bats infest, and in soil), and a thorough reference list including English, French, and Spanish language references.

Postinflammatory lymphedema is a condition characterized by swelling of the soft tissues in which an excessive amount of lymph has accumulated, and is caused by repeated bacterial infections.

History and examination by a physician with characteristic signs and symptoms are sufficient in many cases in ruling out systemic causes of venous hypertension such as hypervolemia and heart failure. An ultrasound (usually a lower limbs venous ultrasonography) can detect venous obstruction or valvular incompetence as the cause, and is used for planning venous ablation procedures, but it is not necessary in suspected venous insufficiency where surgical intervention is not indicated.

Diagnosis is conducted according to the severity of the symptoms. Initially pulmonary function tests are administered. These tests include the lungs' capability of air intake and outtake, and gas flow of oxygen and carbon dioxide between the body and environment. Following these function tests a CT scan or bronchoscopy will be ordered. The results to the scan and bronchoscopy will display the status of the rare condition. A mild case of tracheobronchomalacia would be if the patient's trachea condenses 50% of its normal space when exhaling. Moderate tracheobronchomalacia would be 25% of the normal trachea space constricting and a severe case would be if the walls touch each other.

Primary lymphedema is a form of lymphedema which is not directly attributable to another medical condition.

It can be divided into three forms, depending upon age of onset: congenital lymphedema, lymphedema praecox, and lymphedema tarda.

Congenital lymphedema presents at birth. Lymphedema praecox presents from ages 1 to 35. This type of lymphedema accounts for 77–94% of all cases of primary lymphedema. Lymphedema tarda presents after age 35. This type of lymphedema usually develops as a result of a developmental abnormality being precipitated by some insult such as trauma, illness, or physical immobility. Compared to secondary lymphedema, primary lymphedema is more likely to involve the face, conjunctiva, and genitalia in association with any limbs involved.

It can be familial.

Clinically, there is a wide spectrum of disease manifestation, making diagnosis somewhat difficult. More severe forms include: (1) the chronic pulmonary form, often occurring in the presence of underlying pulmonary disease; and (2) a disseminated form, which is characterized by the progressive spread of infection to extra-pulmonary sites. Oral manifestations have been reported as the main complaint of the disseminated forms, leading the patient to seek treatment, whereas pulmonary symptoms in disseminated disease may be mild or even misinterpreted as flu. Histoplasmosis can be diagnosed by samples containing the fungus taken from sputum (via bronchoalveolar lavage), blood, or infected organs. It can also be diagnosed by detection of antigens in blood or urine samples by ELISA or PCR. Antigens can cross-react with antigens of African histoplasmosis (caused by Histoplasma duboisii), blastomycosis, coccidioidomycosis, paracoccidioidomycosis, and Penicillium marneffei infection. Histoplasmosis can also be diagnosed by a test for antibodies against "Histoplasma" in the blood. "Histoplasma" skin tests indicate whether a person has been exposed, but do not indicate whether they have the disease. Formal histoplasmosis diagnoses are often confirmed only by culturing the fungus directly. Sabouraud agar is one type of agar growth media on which the fungus can be cultured. Cutaneous manifestations of disseminated disease are diverse and often present as a nondescript rash with systemic complaints. Diagnosis is best established by urine antigen testing, as blood cultures may take up to 6 weeks for diagnostic growth to occur and serum antigen testing often comes back with a false negative before 4 weeks of disseminated infection.
