Löfgren Syndrome: A Case Report and Treatment Challenge.

Sarcoidosis is an inflammatory and immune-mediated multisystemic disorder of unknown etiology, characterized by the presence of non-caseating granulomas, impacting various organs. This indolent condition manifests with numerous nonspecific symptoms and lacks a definitive diagnostic test, typically requiring histopathologic confirmation. However, a distinct and more readily diagnosable form of sarcoidosis does exist. The Löfgren syndrome (LöS) is characterized by the triad of erythema nodosum (EN), bilateral hilar lymphadenopathy, and symmetrical inflammatory arthralgias or arthritis. The simultaneous presence of these elements obviates the necessity for a biopsy. Predominantly affecting women in their second and third decades of life, this syndrome generally carries a favorable prognosis with spontaneous resolution or the requirement for a nonsteroidal anti-inflammatory drug (NSAID) alone. Despite its rarity, in particular cases, the treatment can be more challenging. This article presents a case study of LöS in a young woman, whose more aggressive disease course led to the need for steroidal therapy.
