Abstract

Cutaneous involvement in tuberculosis is uncommon and includes several clinical entities, including the erythema induratum of Bazin, whose classic presentation involves purplish nodules or nodular plaques that tend to ulcerate and evolve into outbreaks. In this report, we describe a case of atypical clinical presentation of erythema induratum of Bazin in a 17-year-old patient who presented with crusty, scaly and hyperemic lesions on her legs, which had been progressing for approximately 3 years without signs of systemic involvement. Diagnostic investigation corroborated this hypothesis through the epidemiological link and compatible anatomopathological studies and by ruling out the most common differential diagnoses. The patient showed clinical improvement after starting the anti-tuberculosis medications, and the lesions completely disappeared at the end of the treatment.
