Does sarcoidosis have erythema nodosum?
Erythema nodosum is the most common nonspecific cutaneous lesion of sarcoidosis. 4 It represents a hypersensitivity reaction to a number of possible stimuli, including medications, infections, and inflammatory diseases.
How does sarcoidosis cause erythema nodosum?
Erythema nodosum is a nonspecific skin lesion associated with sarcoidosis. Specific sarcoidosis skin lesions are the result of granulomatous inflammation of the skin, whereas nonspecific sarcoidosis skin lesions develop from a reactive process without granuloma formation.
How is sarcoidosis arthritis diagnosed?
The diagnosis sarcoid arthritis was based on the presence of arthritis in combination with bilateral hilar lymph node enlargement on a chest x ray examination routinely made upon presentation of any patient to the EAC.
How is skin sarcoidosis diagnosed?
Cutaneous sarcoidosis is generally diagnosed through a skin biopsy. Chest x-rays and lung biopsies may also be performed to confirm a diagnosis of sarcoidosis, because cutaneous sarcoidosis usually accompanies granuloma formation in other organs and most commonly the lungs.
Is erythema nodosum and autoimmune disorder?
Erythema nodosum is a localized inflammatory lesion that forms nodules within adipose tissue and is sometimes associated with autoimmune disease, although many cases are idiopathic.
Can a dermatologist diagnose sarcoidosis?
Your dermatologist can play a role in diagnosing sarcoidosis by carefully examining your skin for: Lumps, bumps, and other signs. Scars and tattoos (sarcoidosis can develop in one)
Is erythema nodosum a disease?

What autoimmune disease is linked with erythema nodosum?
Erythema nodosum often occurs in association with granulomatous disease, including sarcoidosis, tuberculosis, and granulomatous colitis.
How is erythema nodosum a sign of systemic disease?
Drug and hormonal reactions, inflammatory bowel disease, and sarcoidosis are other common causes among adults. 1, 2 Often, erythema nodosum is a sign of a serious disorder that potentially is treatable; management of an underlying etiology is the most definitive means of alleviating erythema nodosum.
Can a chronic erythema nodosum form a larger plaque?
Chronic erythema nodosum can join to form larger plaques as well, although they are less inflamed compared with those of typical erythema nodosum. These variants constitute a small minority of erythema nodosum cases.
How are systemic steroids used to treat erythema nodosum?
In patients with erythema nodosum, pain can be managed with nonsteroidal anti-inflammatory drugs. Systemic steroids at a dosage of 1 mg per kg daily may be used until resolution of erythema nodosum if underlying infection, risk of bacterial dissemination or sepsis, and malignancy have been excluded by a thorough evaluation.
What kind of biopsy is needed for erythema nodosum?
A deep incisional or excisional biopsy specimen should be obtained for adequate visualization. Erythema nodosum represents an inflammatory process involving the septa between subcutaneous fat lobules, with an absence of vasculitis and the presence of radial granulomas.
