A large verrucous plaque on the buttocks: A case report of an atypical presentation of tuberculosis verrucosa cutis

Abstract

Although the incidence of cutaneous TB has declined among all cases in dermatology outpatient settings, atypical cases are still being reported worldwide. These atypical forms can imitate other conditions hence delaying the diagnosis and increased morbidity. We report a case of an atypical presentation of extensive Tuberculosis Verrucosa Cutis (TVC) on the buttocks presenting as an annular hyperkeratotic plaque with central healing. Suspicious clinical manifestations and histopathological features followed by an excellent response with antituberculosis therapy confirmed the diagnosis of TVC. Recalcitrant chronic lesions even with adequate standard treatment should raise suspicion of cutaneous TB, especially in endemic areas.
