Löfgren syndrome consists of the triad of erythema nodosum, bilateral hilar lymphadenopathy on chest radiograph, and joint pain.[citation needed]
Genetics
Recent studies have demonstrated that the HLA-DRB1*03 is strongly associated with Löfgren syndrome.[6]
Diagnosis
The triad of erythema nodosum, acute arthritis, and bilateral hilar lymphadenopathy is highly specific (>95%) for the diagnosis of Löfgren syndrome. When the triad is present, further testing with additional imaging and laboratory testing is unnecessary.[citation needed]
Treatment
NSAIDs (nonsteroidal anti-inflammatory drugs) are the usual recommended treatment for Löfgren syndrome.[7] Colchicine or low-dose prednisone may also be used.
Prognosis
Löfgren syndrome is associated with a good prognosis, with > 90% of patients experiencing disease resolution within 2 years. In contrast, patients with the disfiguring skin condition lupus pernio or cardiac or neurologic involvement rarely experience disease remission.[citation needed]
