What is Erythema Nodosum?

Erythema nodosum is an inflammatory disorder of the subcutaneous fat that affects the lower legs and shins. It is characterized by tender, reddish-purple lumps that can range in size from a few millimeters to several centimeters.

Common triggers include certain medications, infections, and inflammatory diseases. Other possible causes include pregnancy, sarcoidosis, inflammatory bowel disease, and Behcet’s disease.

How is Erythema Nodosum Diagnosed?

The diagnosis of erythema nodosum is usually based on the physical examination of the affected area. The condition is usually easily recognizable due to the presence of tender, reddish-purple lumps.
