All red is not always bacterial cellulitis: a case of Löfgren's syndrome.

Löfgren's syndrome is a rare variant of sarcoidosis characterized by the triad of hilar adenopathy, acute polyarthritis, and erythema nodosum. It can be the first presentation of underlying sarcoidosis. Also, the initial presentation of Löfgren's syndrome may be confused with cellulitis. This is a self-limiting disease with a very good prognosis. Non steroidal anti-inflammatory drugs (NSAIDs), along with supportive care and close monitoring, are the mainstay for treatment.
