Löfgren Syndrome: A Case Report and Treatment Challenge

Area of Science:

• Immunology
• Rheumatology
• Pulmonology

Background:

• Sarcoidosis is a multisystemic inflammatory disease of unknown cause, typically diagnosed via biopsy due to nonspecific symptoms.
• Löfgren syndrome (LöS) is a specific clinical presentation of sarcoidosis characterized by erythema nodosum, bilateral hilar lymphadenopathy, and arthralgia/arthritis.
• LöS often affects young women and typically has a favorable prognosis, often resolving spontaneously or with NSAID treatment.

Observation:

• This article details a case study of Löfgren syndrome in a young woman.
• The patient presented with an unusually aggressive disease course.
• The aggressive nature of the LöS necessitated treatment beyond standard NSAIDs.

Findings:

• The classic triad of erythema nodosum, bilateral hilar lymphadenopathy, and arthralgia/arthritis allowed for a clinical diagnosis of LöS, bypassing the need for biopsy.
• Despite the generally favorable prognosis of LöS, this case demonstrated a more severe manifestation.
• Steroidal therapy was required to manage the patient's aggressive Löfgren syndrome.

Implications:

• This case underscores that while Löfgren syndrome is often benign, atypical aggressive presentations can occur.
• Clinicians should be aware of potential treatment challenges in severe LöS cases.
• Further research may elucidate factors contributing to aggressive sarcoidosis phenotypes like this LöS case.
