A Case of Erythema Induratum Case Presenting with Non-Healing Diabetic Foot Ulcer

ABSTRACT

Erythema induratum of Bazin is known as a hypersensitivity response due to Mycobacterium tuberculosis. Generally, it is diagnosed by a negative skin biopsy, negative culture of Mycobacterium tuberculosis and by regression of the lesions after anti-tuberculosis therapy. We present this case to shed light on this rarely observed condition during which lesions may regress via anti-tuberculosis therapy and to point out that tuberculosis therapy should be considered for cases with non-healing diabetic foot ulcer.
