Death may occur rapidly with acute, massive pulmonary bleeding or over longer periods as the result of continued pulmonary failure and right heart failure. Historically, patients had an average survival of 2.5 years after diagnosis, but today 86% may survive beyond five years.

Corticosteroids are the mainstay of treatment of IPH, though they are controversial and lack clear evidence in their favour. They are thought to decrease the frequency of haemorrhage, while other studies suggest that they do not have any effect on the course or prognosis of this disease. In either case, steroid therapy has significant side effects. Small trials have investigated the use of other medications, but none has emerged as a clear standard of care. This includes immune modulators such as hydroxychloroquine, azathioprine, and cyclophosphamide. 6-mercaptopurine as a long-term therapy may prevent pulmonary haemorrhage. A 2007 scientific letter. reports preliminary success in preventing pulmonary haemorrhage with the anti-oxidant N-acetylcysteine.

Brown induration is fibrosis and hemosiderin pigmentation of the lungs due to long standing pulmonary congestion (chronic passive congestion).

A pulmonary consolidation is a region of (normally compressible) lung tissue that has filled with liquid, a condition marked by induration (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign. Consolidation occurs through accumulation of inflammatory cellular exudate in the alveoli and adjoining ducts. Simply, it is defined as alveolar space that contains liquid instead of gas. The liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery). It must be present to diagnose pneumonia: the signs of lobar pneumonia are characteristic and clinically referred to as consolidation.

Affected workers should be offered alternative employment. Continued exposure leads to development of persistent symptoms and progressive decline in FEV1.

Byssinosis, also called "brown lung disease" or "Monday fever", is an occupational lung disease caused by exposure to cotton dust in inadequately ventilated working environments. Byssinosis commonly occurs in workers who are employed in yarn and fabric manufacture industries. It is now thought that the cotton dust directly causes the disease and some believe that the causative agents are endotoxins that come from the cell walls of gram-negative bacteria that grow on the cotton. Although bacterial endotoxin is a likely cause, the absence of similar symptoms in workers in other industries exposed to endotoxins makes this uncertain.

Of the 81 byssinosis-related fatalities reported in the United States between 1990 and 1999, 48% included an occupation in the yarn, thread, and fabric industry on the victim's death certificate. This disease often occurred in the times of the industrial revolution. Most commonly young girls working in mills or other textile factories would be afflicted with this disease. In the United States, from 1996 to 2005, North Carolina accounted for about 37% of all deaths caused by byssinosis, with 31, followed by South Carolina (8) and Georgia (7).

The term "brown lung" is a misnomer, as the lungs of affected individuals are not brown.

Signs that consolidation may have occurred include:

- Expansion of the thorax on inspiration is reduced on the affected side

- Vocal fremitus is increased on the side with consolidation

- Percussion is dull in affected area

- Breath sounds are bronchial

- Possible medium, late, or pan-inspiratory crackles

- Vocal resonance is increased. Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to in the healthy lung where speech sounds muffled.

- A pleural rub may be present.

- A lower expected Pa02 than calculated in the alveolar gas equation

Unfortunately, response to treatment is not guaranteed. Also, the necrotic skin areas may get infected, and this then may lead to sepsis (i.e. infection of blood with bacteria; sepsis can be life-threatening) in some patients. Overall, the clinical prognosis remains poor.

The optimal treatment is prevention. Rigorous and continuous control of phosphate and calcium balance most probably will avoid the metabolic changes which may lead to calciphylaxis.

There is no specific treatment. Of the treatments that exist, none are internationally recognized as the standard of care. An acceptable treatment could include:

- Dialysis (the number of sessions may be increased)

- Intensive wound care

- Clot-dissolving agents (tissue plasminogen activator)

- Hyperbaric oxygen

- Maggot larval debridement

- Adequate pain control

- Correction of the underlying plasma calcium and phosphorus abnormalities (lowering the Ca x P product below 55 mg2/dL2)

- Sodium thiosulfate

- Avoiding (further) local tissue trauma (including avoiding all subcutaneous injections, and all not-absolutely-necessary infusions and transfusions)

- Urgent parathyroidectomy: The efficacy of this measure remains uncertain although calciphylaxis is associated with frank hyperparathyroidism. Urgent parathyroidectomy may benefit those patients who have uncontrollable plasma calcium and phosphorus concentrations despite dialysis. Also, cinacalcet can be used and may serve as an alternative to parathyroidectomy.

- Patients who receive kidney transplants also receive immunosuppression. Considering lowering the dose of or discontinuing the use of immunosuppressive drugs in people who have received kidney transplants and continue to have persistent or progressive calciphylactic skin lesions can contribute to an acceptable treatment of calciphylaxis.

- A group has reported plasma exchange effective and propose a serum marker and perhaps mediator (calciprotein particles)

The management of lipodermatosclerosis may include treating venous insufficiency with leg elevation and elastic compression stockings; in some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibrinolytic agents use an enzymatic action to help dissolve blood clots.

Stanozol is injected directly into the affected area, Venous Ablation has also been known to help circulation in patients.

Lipodermatosclerosis (also known as "chronic panniculitis with lipomembranous changes", "hypodermitis sclerodermiformis", "sclerosing panniculitis", and "stasis panniculitis") is a skin and connective tissue disease. It is a form of lower extremity panniculitis, an inflammation of the layer of fat under the epidermis.

There is risk of perforation of the esophagus with the use of dilators for treatment. Furthermore, it is one of the risk factors for developing squamous cell carcinoma of the oral cavity, esophagus, and hypopharynx.

There are suggestions in the medical literature that treatment with radioactive iodine for Graves' hyperthyroidism may be a trigger for pretibial myxedema which would be consistent with radioiodine ablation causing or aggravating ophthalmopathy, a condition which commonly occurs with pretibial myxedema and is believed to have common underlying features.

Other known triggers for ophthalmopathy include thyroid hormone imbalance, and tobacco smoking, but there has been little research attempting to confirm these are also risk factors for pretibial myxedema.

Good nutrition with adequate intake of iron may prevent this disorder. Good nutrition should also include balanced diet and exercise.

Pretibial myxedema (myxoedema (UK), also known as Graves' dermopathy, thyroid dermopathy, Jadassohn-Dösseker disease or Myxoedema tuberosum) is an infiltrative , resulting as a rare complication of Graves' disease, with an incidence rate of about 1-5% in patients.

Treatment may be requested for cosmetic reasons. Traditional techniques such as surgical excision are effective but will leave a scar. Laser therapy has become the mainstay of therapy.

Published research suggests that the Long Pulsed Nd:YAG laser is a very effective, with a clearance rate of 94% following a single treatment. In this study no scarring or other complications were reported.

There is no effective treatment for this condition. It has been reported that clearance of lesions can be done with melphalan and cyclophosphamide alone or in combination with prednisone. Both isotretinoin and etretinate have also been shown to improve the conditions. All medications listed can cause adverse symptoms, with isotretinoin and etretinate particularly dangerous since they are both teratogens. Other attempted treatments include interferon-alpha, cyclosporine, PUVA photochemotherapy, electron-beam therapy, IVIg, and dermabrasion. However, the overall prognosis for the disease is poor. There are reported instances of remission of the disease when treated with a combination of Revlimid and Dexamethasone over a 24-month period.

Multifocal lymphangioendotheliomatosis (also known as "Congenital cutaneovisceral angiomatosis with thrombocytopenia," and "Multifocal Lymphangioendotheliomatosis with thrombocytopenia") presents at birth with hundreds of red-brown plaques as large as several centimeters.

Acroangiodermatitis of Mali (also known as "Mali acroangiodermatitis" and "Pseudo-Kaposi's sarcoma") is a rare cutaneous condition often characterized by purplish-blue to brown papules and plaques on the medial and lateral malleolus of both legs.

Acroangiodermatitis is a rare skin condition characterised by hyperplasia of pre-existing vasculature due to venous hypertension from severe chronic venous stasis. It is associated with amputees, haemodialysis (HD) patients with arteriovenous (AV) shunts, and patients with paralysed legs, hepatitis C, chronic venous insufficiency or AV malformations (AVM). Patients present with itchy, painful, confluent, violaceous or brown-black macules, papules or plaques usually at the distal lower limbs. There may be ulceration and bleeding. The histologic features are capillary proliferation and perivascular inflammation involving eosinophils in the dermis with minimal epidermal changes. Management includes compression therapy, wound care and surgical correction of AVM. Dapsone combined with leg elevation and compression, and erythromycin for HD patients with AV fistulas have also been reported. The lesions may persist for years with complications like ulceration, bleeding and infection.

Treatment with compression stockings should be offered to patients with lower extremity superficial phlebitis, if not contraindicated (e.g., peripheral artery disease). Patients may find them helpful for reducing swelling and pain once the acute inflammation subsides.

Nonsteroidal anti-inflammatory drugs (NSAID) are effective in relieving the pain associated with venous inflammation and were found in a randomized trial to significantly decrease extension and/or recurrence of superficial vein thrombosis.

Anticoagulation for patients with lower extremity superficial thrombophlebitis at increased risk for thromboembolism (affected venous segment of ≥5 cm, in proximity to deep venous system, positive medical risk factors).

Treatment with fondaparinux reduces the risk of subsequent venous thromboembolism.

Surgery reserved for extension of the clot to within 1 cm of the saphenofemoral junction in patients deemed unreliable for anticoagulation, failure of anticoagulation and patients with intense pain. Surgical therapy with ligation of saphenofemoral junction or stripping of thrombosed superficial veins appears to be associated higher rates of venous thromboembolism compared with treatment with anitcoagulants.

Sun avoidance, avoidance of tanning booths, and usage of broad spectrum sunscreen that blocks both UVA and UVB.

Identification and avoidance of the offending drug.

Xanthoma disseminatum (also known as "Disseminated xanthosiderohistiocytosis" and "Montgomery syndrome") is a rare cutaneous condition that preferentially affects males in childhood, characterized by the insidious onset of small, yellow-red to brown papules and nodules that are discrete and disseminated.

It is a histiocytosis syndrome.

Idiopathic eruptive macular pigmentation is a skin condition developing in young persons, with an average age of 11, characterized by asymptomatic widespread brown to gray macules of up to several centimeters in diameter on the neck, trunk, and proximal extremities.

Stiff skin syndrome (also known as "Congenital fascial dystrophy") is a cutaneous condition characterized by ‘rock hard’ induration, thickening of the skin and subcutaneous tissues, limited joint mobility, and mild hypertrichosis in infancy or early childhood. Immunologic abnormalities or vascular hyperactivity are not present in patients.

Not much is known about it, cause or treatment, as it has only been reported 41 times throughout history. Not much is known about this, and further investigation is required.According to news reports on one particular patient by name of Jaiden Rogers, the patient's skin hardens in some places, and it slowly spreads over the surrounding area. For Rogers, it's spreading over the back, legs, and hips, inhibiting his ability to walk. He say it hurts, but finds it difficult to describe the sensations further. Currently, it appears that chemotherapy similar to that used for cancer is slowing the spread, but it also appears that once the skin has hardened it cannot revert to its healthy flexible state. Physical therapy also appears to help. Further investigation is required.

Some 125,000 cases a year have been reported in the United States, but actual incidence of spontaneous thrombophlebitis is unknown.

A fourfold increased incidence from the third to the eight decade in men and a preponderance among women of approximately 55-70%.

The average mean age of affected patients is 60 years.

Thrombophlebitis can develop along the arm, back, or neck veins, the leg is by far the most common site. When it occurs in the leg, the great saphenous vein is usually involved, although other locations are possible.
