Erythema nodosum is self-limiting and usually resolves itself within 3–6 weeks. A recurring form does exist, and in children it is attributed to repeated infections with streptococcus. Treatment should focus on the underlying cause. Symptoms can be treated with bedrest, leg elevation, compressive bandages, wet dressings, and nonsteroidal anti-inflammatory agents (NSAIDs). NSAIDs are usually more effective at the onset of EN versus with chronic disease.

Potassium iodide can be used for persistent lesions whose cause remains unknown. Corticosteroids and colchicine can be used in severe refractory cases. Thalidomide has been used successfully in the treatment of Erythema nodosum leprosum, and it was approved by the U.S. FDA for this use in July 1998.

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.

Treatment protocol is not well established. Some sources report that approximately half of the patients will fully recover after lengthy (mean time 14.5 months, range 2–24 months) expectant management.

Treatment with steroids is lengthy and usually requires about 6 months. While some source report very good success with steroids most report a considerable risk of recurrence after a treatment with steroids alone. Steroids are known to cause elevation of prolactin levels and increase risk of several conditions such as diabetes, and other endocrinopathies which in turn increase the risk of IGM. Treatment with topical steroids to limit side effects was also reported in one case. For surgical treatment recurrence rates of 5-50% have been reported.

A 1997 literature review article recommended complete resection or corticosteroid therapy, stating also that long-term follow-up was indicated due to a high rate of recurrence.

Treatment with a combination of glucocorticoids and prolactin lowering medications such as bromocriptine or cabergoline was used with good success in Germany. Prolactin lowering medication has also been reported to reduce the risk of recurrence. In cases of drug-induced hyperprolactinemia (such as antipsychotics) prolactin-sparing medication can be tried.

Methotrexate alone or in combination with steroids has been used with good success. Its principal mechanism of action is immunomodulating activity, with a side effect profile that is more favorable for treating IGM.

Colchicine, azathioprine and NSAIDs have also been used.

Corticosteroids remain the main treatment modality for IOI. There is usually a dramatic response to this treatment and is often viewed as pathognomonic for this disease. Although response is usually quick, many agree that corticosteroids should be continued on a tapering basis to avoid breakthrough inflammation.

Although many respond to corticosteroid treatment alone, there are several cases in which adjuvant therapy is needed. While many alternatives are available, there is no particular well-established protocol to guide adjuvant therapy. Among the available options there is: surgery, alternative corticosteroid delivery, radiation therapy, non-steroidal anti-inflammatory drugs, cytotoxic agents (chlorambucil, cyclophosphamide), corticosteroid sparing immunosuppressants (methotrexate, cyclosporine, azathioprine), IV immune-globin, plasmapheresis, and biologic treatments (such as TNF-α inhibitors).

AIP often completely resolves with steroid treatment. The failure to differentiate AIP from malignancy may lead to unnecessary pancreatic resection, and the characteristic lymphoplasmacytic infiltrate of AIP has been found in up to 23% of patients undergoing pancreatic resection for suspected malignancy who are ultimately found to have benign disease. In this subset of patients, a trial of steroid therapy may have prevented a Whipple procedure or complete pancreatectomy for a benign disease which responds well to medical therapy. "This benign disease resembles pancreatic carcinoma both clinically and radiographically. The diagnosis of autoimmune pancreatitis is challenging to make. However, accurate and timely diagnosis may preempt the misdiagnosis of cancer and decrease the number of unnecessary pancreatic resections." Autoimmune pancreatitis responds dramatically to corticosteroid treatment.

If relapse occurs after corticosteroid treatment or corticosteroid treatment is not tolerated, immunomodulators may be used. Immunomodulators such as azathioprine, and 6-mercaptopurine have been shown to extend remission of autoimmune pancreatitis after corticosteroid treatment. If corticosteroid and immunomodulator treatments are not sufficient, rituximab may also be used. Rituximab has been shown to induce and maintain remission.

Treatment may involve surgery, which is currently the only recommended intervention. Surgery should include the removal of even small nodules, to prevent the recurrence of the scrotal calcinosis.

Healing is prolonged, and usually takes 6–10 weeks. The ulcer heals by secondary intention.

In terms of possible treatment for the condition of idiopathic sclerosing mesenteritis, medications such as corticosteroids, tamoxifen and thalidomide have been used.

Treatment consists primarily of immunosuppressive drugs (e.g., hydroxychloroquine and corticosteroids). An interesting second line drug is methotrexate in its low-dose schedule. In 2011, the U.S. Food and Drug Administration (FDA) approved the first new drug for lupus in more than 50 years to be used in the US, belimumab. In addition to medicative therapy, due to the psychological and social impacts that Lupus may have on an individual, Cognitive Behavioural Therapy (CBT) has also been demonstrated to be effective in reducing stress, anxiety, and depression in lupus sufferers.

Prognosis is usually good, however recurrence may happen with rate up to 16%. Presence of myxoid structures in the pyogenic granuloma may be the main cause of recurrence.

Although pyogenic granulomas are not infectious or malignant, treatment may be considered because of bleeding or ulceration. Frequently, pyogenic granulomas are treated with electrodesiccation (cauterization) and curettage (excision), though laser treatment using pulsed dye laser or CO laser is often effective.

Several reports have demonstrated the efficacy of topical application of the beta-adrenergic antagonist timolol in the treatment of pediatric pyogenic granuloma.

There is usually no treatment if the pyogenic granuloma occurs during pregnancy since the lesion may heal spontaneously. Recurrent bleeding in either oral or nasal lesions may necessitate excision and cauterization sooner, however. If aesthetics are a concern, then treatment may be pursued as well. Usually, only minor surgery may be needed, along with a dental cleaning for oral lesions to remove any calculus or other source of irritation. For nasal lesions, nose-picking should be discouraged.

Treatment of AIGA almost always consists of steroid pulse therapy or high-dose oral steroids and is not consistently effective. Much remains unclear regarding the reasons for recurrent anhidrosis.

Initial and general approach for AGL patients are to treat the metabolic complications such as leptin-replacement therapy and/or to control the abnormal levels of lipids or glucose levels. Anti-diabetic medications such as insulin, metformin, or thiazolidinediones are used for insulin-resistance or high glucose levels, or statins or fibrates are used for hyperlipidemia. If symptoms persist, metreleptin can be prescribed.

Metreleptin (MYALEPT) is a recombinant human leptin analog and was approved by FDA in 2014 for generalized lipodystrophy as an adjunct therapy to diet to treat the complication of leptin deficiency. It is the only drug option approved for generalized lipodystrophy-related symptoms and is not intended to use for patients with HIV-related lipodystrophy or complications of partial lipodystrophy. Although it is a recombinant human leptin analog, it is not completely the same as natural leptin as it is produced in "e. coli" and has added methionine residues at is amino terminus. It works by binding to the human leptin receptor, ObR, and activates the receptor. The receptor belongs to the Class I cytokine family and signals the JAK/STAT pathway. It is available as 11.3 mg powder in a vial for subcutaneous injection upon reconstitution and needs to be protected from the light. For treatment, patients and their doctors need to be enrolled and certified in the Myalept Risk Evaluation and Mitigation Strategy (REMS) Program because people on this treatment has a risk of developing anti-metreleptin antibodies that decrease the effectiveness of metreleptin, and increased risk of lymphoma. Clinical study with GL patients who took metreleptin had increased insulin sensitivity, as indicated by decreased HbA1c and fasting glucose level, and reduced caloric intake as well as fasting triglyceride levels.

Plasmapheresis was previously an option for lowering extremely high triglyceride levels for preventing pancreatitis and painful xanthoma, but its use has been decreased after the approval of metreleptin.

Cosmetic treatments, such as facial reconstruction or implants, can be done to replace adipose tissues.

Lifestyle modifications are also recommended, including changes into less fat diet and exercise.

The prognosis of the disease is unknown as of December, 2017.

Weber–Christian disease, also known as relapsing febrile nodular nonsuppurative panniculitis, is a cutaneous condition characterized by recurrent subcutaneous nodules that heal with depression of the overlying skin.

It is type of panniculitis.

It is a rare disease seen in females 30–60 years of age. It is a recurring inflammation of fatty layers of tissue present beneath the skin. Clinical course is characterised by exacerbations and remissions. Lesions are bilaterally symmetrical and are usually seen in the lower legs.

People with lung disease due to A1AD may receive intravenous infusions of alpha-1 antitrypsin, derived from donated human plasma. This augmentation therapy is thought to arrest the course of the disease and halt any further damage to the lungs. Long-term studies of the effectiveness of A1AT replacement therapy are not available. It is currently recommended that patients begin augmentation therapy only after the onset of emphysema symptoms.

As of 2015 there are four IV augmentation therapy manufacturers in the United States, Canada, and several European countries. Intravenous (IV) therapies are the standard mode of augmentation therapy delivery. Researchers are exploring inhaled therapies. IV augmentation therapies are manufactured by the following companies and have been shown to be clinically identical to one another in terms of dosage and efficacy.

Augmentation therapy is not appropriate for people with liver disease; treatment of A1AD-related liver damage focuses on alleviating the symptoms of the disease. In severe cases, liver transplantation may be necessary.

Unlike other autoinflammatory disorders, patients with CANDLE do not respond to IL-1 inhibition treatment in order to stop the autoinflammatory response altogether. This suggests that the condition also involves IFN dysregulation.

Treatment of lung disease may include bronchodilators, inhaled steroids, and when infections occur antibiotics. Intravenous infusions of the A1AT protein or in severe disease lung transplantation may also be recommended. In those with severe liver disease liver transplantation may be an option. Avoiding smoking and vaccination for influenza, pneumococcus, and hepatitis is also recommended.

Alpha-1 antitrypsin deficiency panniculitis is a panniculitis associated with a deficiency of the α-antitrypsin enzyme.

Erythema nodosum is a form of panniculitis characterised by tender red nodules, 1–10 cm, associated with systemic symptoms including fever, malaise, and joint pain. Nodules may become bluish-purple, yellowing, and green, and subside over a period of 2–6 weeks without ulcerating or scarring. Erythema nodosum is associated with infections, including Hepatitis C, EBV and tuberculosis, Crohn's disease and sarcoidosis, pregnancy, medications including sulfonamides, and some cancers, including Non-Hodgkin lymphoma and pancreatic cancer.

It is named after Frederick Parkes Weber and Henry Asbury Christian.

Erythema nodosum (EN), also known as subacute migratory panniculitis of Vilanova and Piñol, is an inflammatory condition characterised by inflammation of the fat cells under the skin, resulting in tender red nodules or lumps that are usually seen on both shins. It can be caused by a variety of conditions, and typically resolves spontaneously within 30 days. It is common in young people between 12–20 years of age.

Many researches for the treatment of lipodystrophy focus on the safety and efficacy of leptin replacement therapy and the outlook is positive in many studies.

According to a prospective, open-label clinical study at the NIH, metreleptin decreased the fasting glucose level from 180 mg/dL to 121 mg/dL, HbA1c from 8.4% to 6.4%, total cholesterol from 214 mg/dL to 146 mg/dL, and triglycerides from 467 (200-847)mg/dL to 180 (106-312)mg/dL after 12 months of use (p<0.001). Patients also had decreased use of anti-diabetic medications, lipid-lowering medications, and insulin (p<0.001). In other clinical reports studying 3 patients diagnosed with AGL accompanied by hypoleptinemia, uncontrolled diabetes, and hypertriglyceridemia who were treated with metreleptin for 12–168 weeks, patients had great reduction in HbA1c, from 10.9% to 5.8%, and had normalized serum triglycerides with a mean decline of 90%. Patients reported improved quality of life and reduced need for other medications without significant adverse effects.

One research published in 2017 reported an middle-aged patient developed AGL after treatment and recovery for autoimmune thrombocytopenia that included immunoglobulin therapy and prednisone, which suggests the autoimmune trigger may contribute to the development of AGL.

Other researches focus on genetics of lipodystrophy; however its relevance to acquired generalized lipodystrophy has not been confirmed so far. One clinical report published in July 2017 stated two brothers with juvenile-onset generalized lipodystrophy was due to lamin C-specific mutation but it is unknown at this point if this will fall into acquired or familial lipodystrophy.

There has been many published case reports. Meta-analysis of published case reports published within the decade will be very helpful in establishing patient demographic, etiologies, and prognosis of the diagnosis.

Septal panniculitis is a condition of the subcutaneous fat affecting the layer of adipose tissue that lies between the dermis and underlying fascia, of which there are two forms: acute erythema nodosum and chronic erythema nodosum.

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.

Lupus erythematosus panniculitis (also known as "Lupus erythematosus profundus", "Lupus panniculitis", "Lupus profundus", and "Subcutaneous lupus erythematosus") presents with subcutaneous nodules that are commonly firm, sharply defined and nontender.

At least one study suggests that gluten neuropathy can be effectively treated with a gluten-free diet. In the study, 35 patients with gluten neuropathy adhered to a gluten-free diet, where adherence was monitored serologically. After one year, the treatment group had improved significantly compared to the control group. The indicators of improvements were improvements of sural sensory action potential and subjective improvement of neuropathic symptoms. Subgroup analysis suggested that severe neuropathy might imply reduced capacity for recovery of the peripheral nerves or longer recovery.
