This patient has Lofgren's syndrome (acute presentation of sarcoidosis).
In another study, the same investigators reported on the clinical features and course of Lofgren's syndrome in 186 patients.
Johan Grunewald, MD, and Anders Eklund, MD, reported on 150 patients with Lofgren's syndrome.
A clinical variant of sarcoidosis characterized by erythema nodosum, arthritis, and mediastinal lymphadenopathy
It is important to identify Lofgren's syndrome (consisting of erythema nodosum, bilateral hilar adenopathy, migratory polyarthritis and fever), as not only does it have a good prognosis, but it is also made without the need for histological proof.
The one exception is in patients with classic Lofgren's syndrome (see above).
The prognosis of sarcoidosis is variable, with Lofgren's syndrome having the best prognosis, with a high probability of spontaneous relapse.
Herein, we report a rare case of undifferentiated SpA (uSpA) presenting in conjunction with anterior uveitis in a patient with Lofgren's syndrome during remission (while taking no medication).
His medical history revealed Lofgren's syndrome, a single episode of arthralgia, erythema nodosum, and bilateral hilar lymphadenopathy that had been ongoing for the past 20 years.
The combination of erythema nodosum, periarticular ankle inflammation, and mediastinal lymphadenopathy is designated as Lofgren's syndrome, which usually has a self-limiting course with spontaneous resolution.
4) In this article, a case of Lofgren's syndrome with sacroiliitis is presented.
The patient was diagnosed as having Lofgren's syndrome, which is a clinical subtype of acute sarcoidosis involving acute arthritis, LAP, and EN.
