Erythema Induratum of Bazin – Tuberculosis in disguise

Abstract

Erythema Induratum of Bazin (EIB) is a tuberculid showing lobular panniculitis. EIB is classified under cutaneous tuberculosis. A diagnosis of EIB is based on cutaneous characteristics, a positive mantoux test, evidence of tuberculosis and histopathological findings. We present a case of a 43-year-old lady with recurrent crops of nodules on legs. Mantoux test was positive. Histopathology revealed lobular panniculitis, epithelioid cells, lymphocytes and giant cells surrounding foci of caseous necrosis which was suggestive of erythema induratum. Her lesions responded to antitubercular therapy (ATT).
