A case report of erythema induratum of Bazin's disease.

INTRODUCTION: Erythema induratum remains one of the rarely encountered tuberculid although tuberculosis is known to be endemic in the developing countries. We report a case of erythema induratum recently encountered in our centre.

CLINICAL FEATURE: Clinically, erythema induratum typically manifests as ulcerative and indurated lesions on the lower limbs, especially the calves. TREATMENT OUTCOME: The patient responded well to a course of anti-tuberculous therapy with marked resolution of the lesions, suggesting the aetiological role of Mycobacterium tuberculosis in this condition.

CONCLUSION: A short review of the distinguishing features of erythema induratum, the associated classical histological spectrum and the usefulness of polymerase chain reaction in the diagnosis of erythema induratum is given. A search for active foci of tuberculosis is advocated in all cases.
