Erythema Nodosum
Introduction
Erythema nodosum is a specific form of Panniculitis characterized by tender, red or violet, palpable, subcutaneous nodules on the shins and occasionally other locations. It often occurs with an underlying systemic disease, notably streptococcal infections, sarcoidosis, and inflammatory bowel disease. Diagnosis is by clinical evaluation and sometimes biopsy. Treatment depends on the cause. Erythema nodosum primarily affects people in their 20s and 30s but can occur at any age; women are more often affected.
