Erythema induratum is a rare granulomatous lobular panniculitis that most commonly affects women in their 40s. The term “erythema induratum of Bazin” refers to the tuberculosis-associated lesions, and “erythema induratum of Whitfield” refers to lesions that are nontuberculous. It presents as tender erythematous subcutaneous nodules on the lower extremities. Other conditions such as erythema nodosum should be ruled out. Histologically, erythema induratum is described as a lobular panniculitis and may include vasculitis. There have been few reported cases in the United States. In this case report, we will discuss the clinical features, histopathology, differential diagnosis, and management of erythema induratum.
