5-Minute Clinical Consult: Erythema Nodosum

Erythema Nodosum

CLINICAL PEARLS

Löfgren syndrome (erythema nodosum and hilar adenopathy) is seen with multiple etiologies and does not exclusively indicate sarcoid.
The clinical variant of erythema nodosum migrans (subacute nodular migratory panniculitis) is often unilateral with nodules fewer in number, smaller in size, and longer lasting that extend radially by division into smaller nodules.
In patients with a history of Hodgkin lymphoma, erythema nodosum is a warning of impending recurrence.
