A 45-year-old female presented with a solitary, asymptomatic red-brown arcuate plaque over the right forearm for 7 years. The lateral edge had an active infiltrated margin with trailing scar and hypopigmentation [Figure 1]. Based on histopathological findings of epithelioid granulomas in the dermis and epidermal changes, strong Mantoux test positivity, and response to antituberculous therapy, diagnosis of lupus vulgaris was confirmed. Lupus vulgaris originates from an underlying tuberculosis focus as a small, reddish-brown, flat plaque which extends peripherally with areas of atrophy.[1] The treatment is multidrug antituberculosis therapy.
